Abstract: Class of high performance thermosetting materials com­ posed of polyarylene polyether resins having each of their ends capped with a monovalent unsaturated organo radical. The end-capped polyarylene polyether resins have the formu­ la: Z (polyarylene polyether chain)Z′ wherein Z and Z′ are each a monovalent unsaturated organo radical. Usually Z and Z′ are alkylene, aralkylene or cycloalky­ lene moieties.

Field Of This Invention The invention relates to thermosetting end-capped polyarylene polyethers, including end-capped polyarylene polyethers, processes of preparing and using such resins, composites containing such resins, and homopolymers and copolymers prepared from such resins. 2. Prior Art -Thermoplastic polyarylene' polyethers are known. Thermoplastic silane end-capped polyarylenepolyethers and -thermoplastic polysiloxane-polyarylene polyether copolymers are also known. BROAD DESCRIPTION OF THE INVENTION An object of the invention is to provide a new and useful class of high performance end-capped polyarylene polyethers, particularly end-capped polysulfones. Another object of the invention is to provide compositions containing and copolymers produced from such polyarylene polyethers and comonomers. Another object of this invention is to provide homopolymers prepared from such polyarylene polyethers. A further object of the invention is to provide processes for preparing and using such polyarylene polyethers, compositions homopolymers and copolymers. A still further object of the invention is to provide a composite of a substrate and such polyarylene polyethers, homopolymers and copolymers. Other objects and advantages of the invention are set out herein or are obvious here from to one ordinarily skilled in the art. The objects and advantages of the invention are achieved by the thermosetting polyarylene polyethers and so forth of the invention. The thermosetting, monovalent unsaturated organo end-capped polyarylene polyethers of the invention differ from the known thermoplastic polyarylene polyethers and the known silane end-capped polyarylene polyethers most significantly in that the compositions of the invention have reactive, monovalent, unsaturated organo end-capping groups. In its broadest sense, the invention involves endcapped polyarylene polyethers having the formula: Z ( polyarylene polyether chain ) Z' wherein Z and Z' are each a monovalent unsaturated organo moiety. The polyarylene polyether chain can be substituted or unsubstituted. The end-capped resins of the invention are a class of organic resins having etheric oxygenvalently connecting together aromatic nuclei or residue of aromatic compounds. These end-capped resins are appropriately termed end-capped polyaryiene polyethers resins. A preferred class of compositions that are within the scope of the invention are the thermosetting end-capped polyarylene polyether resins having the formula: Z-(O-E'-O-E-)nOZ' wherein n is a positive number, Z and Z' are each a monovalent unsaturated organo moiety, E is the residue after removal of the hydroxyl groups of a dihydric phenol, and E' is the residue after removal of the two activated halo groups of an aromatic compound having two activated halo 'substituents.The residues represented by E and E' can be unsubstituted or substituted beyond the already defined degree. These thermosetting resins can be produced by reacting an alkali metalphenoxide end-capped polyarylene polyether with a monovalent, monohalo-substituted unsaturated organo compound. Preferably n is 2 to 300; and preferably Z and Z' are each an alkylene, aralkylene or cyclo alkylene moiety. Another preferred class of compositions that are within the scope of the invention are the thermosetting end-capped polyarylene polyethez ogliomers or resins having the formula: z-(-O-Ar-)-OZ' n wherein n is a positive number, Z and ZI are each a monovalen unsaturated organo moiety, and Ar is a divalentaranatic group that can be the same or different from one -(-O - Art group to the next, and in which each Ar group is bonded to the connecting oxy groups through aromatic carbon atoms. The aromatic group represented by Ar can be substituted or unsubsti tuted, These thermosetting resins can be produced by reactin San alkali metal phenoxide end-capped polyarylene polyether with a monovalent, monohalo-substituted, unsaturated organo compound. Preferably n is 2 to 300; and preferably Z and Z' are each an alkylene, arslkylene.or cycloalkylene moiety. The polyarylene polyether chain, particularly the benzenoid constituents, can contain inert substituents such as halogens (e.g., chlorine, bromide and fluorine) alkyl groups having from 1 to 4 carbon atoms and alkoxy groups having 1 to 4 carbon atoms. The end-capped polyarylene polyether resins of the invention have excellent strength and toughness properties as well as outstanding thermal oxidative and chemicalstability. They find wide utility in the production of shaped and molded articles where such properties are necessary and are highly desirable and also in the preparation of -film and fiber products which have excellent mechanical properties. Heat-hardenable resins can be blended with thermosetting, end-capped polyarylene polyether resins of this invention to yield useful mixtures. The preferred class of end-capped thermosetting resins of the invention are those polysulfones where the thermosetting polyarylene polyether resin is composed of recurring units having the formula: EMI4.1 wherein R is hydrogen, lower alkyl, lower aryl and halogen substituted lower alkyl and lower aryl groups.aost preferably R is methyl. The lower alkyl groups have from 1 to 4 carbon atoms, As often used herein, the polysulfone-vinyl reactive resins or PSF-yR are the above end-capped resins when R is methyl and the end-capping moieties are alkylene,aralkylene or cycloalkylene moieties. Other times herein the phrase polys fone-vnyl reactive resins (PSF-VR) is used as a shorthand reference broadly for the end-capped polyarylene polyether resins. The ability of polysulfone-vinyl reactive resins to be cured by conventional techniques and their ability to copolymerize with a variety of commercially available, inexpensive comonomers, make them an important class of new thermoset resins. Of particular importance is the polysulfone-vinyl reactive styrene binder system which not only forms a true solution in any proportion but also yields a copolymer of uniform, well-defined properties. It can be formulated, processed and cured like an unsaturated polyester resin to impart higher use temperatures, better mechanical and electrical properties, and, above all, improved chemical resistance to strong alkaline environment. The polysulfone-vinyl reactive resins of the invention are particularly useful as (1) corrosion resistance matrix resins or additives, (2) powder coatings, (3) magnet wire coatings, (4) photocurable and radiation coatings and (5) in fiber reinforced structural composites. The thermoset vinyl benzyloxy end-capped polysulfones in coating form on metal sheets and the like are highly resistance to the solvent action to acetone and chlorinated hydrocarbons, such as, methylene chloride. Such coatings are also highly resistant to hot alkali solutions. A thermoset or baked coating of the allyl end-capped polysulfones on a metal or glass substrate is readily removable or strippable once subjected to hot detergent solutions. This property means strippable coating applications to protect glass substrates, particularly to hot alkali solutions for the thermoset allyl-terminated polysulfone coatings of the invention. Similarly, metal protective coatings, such as, metal strip and prime coatings, can coatings, wire magnet coatings and pipe liner coatings ar also applications for the thermoset allyl-terminated polysulfones of the invention. The thermoset vinylbenzyloxy end-capped polysulfone (10,000 molecular weight) had significant resistance to the solvent action of trichloroethylene, which is important in some electrical applications. The end-capped polyarylene polyethers of the invention I have the same advantages and uses as the subgroup end-capped polysulfones of the invention. The invention includes the homopolymers of the endcapped polyarylene polyether having the formula: Z ( polyarylene polyether chain t Z' wherein Z and Z' are each a monovalent unsaturated organo moiety. The polyarylene polyether chain can be substituted o unsubstituted. The homopolymer can be prepared from any of the vinyl reactive end-capped polyarylene polyethers taught o described herein. A preferred class of homopolymers which are within the scope of the invention are the homopolymers of the end-capped polyarylene polyethers having the formula: Z-(-O-E'-O-E-)n-OZ' wherein n is 2 to 300, Z and Z' are each a monovalent unsaturated organo moiety, E is the residue after removal of the hydryoxyl groups of a dihydric phenol and 8' is the residue after removal of the two activated halo groups of an aromatic compound having two activated halo substituents. The residues represented by E and E' being unsubstituted or substituted beyond the already defined degree. Another preferred class of copolymers which are within the scope of the invention are the homopolymers of an endcapped polyarylene polyethers having the formula: Z ( O - Ar 3n OZ' wherein n is 2 to 300, Z and Z' are each a monovalent unsaturated organo moiety, and Ar is a divalent aromatic group that can be the same or different from one ( O - Ar 5 group to the next, and in which each Ar group is bonded to the connecting oxy groups through aromatic carbon atoms. The aromatic group represented by Ar being substituted or unsuostituted. As desired, monomer (B) can have one, two, three or more reactive vinyl groups, depending upon the type of copolymer wanted, speed and cost of curing, etc. The invention also includes the process of preparing suc homopolymers by homopolymerizing the end-capped polyarylene polyether monomer of the invention. The polymerization is effectively conducted in the presence of a free radical initiator, with concurrent heat application being preferred Polymerization can also be effected by means of actinic radia tion, such as ultraviolet light. The invention further includes the copolymers comprised of: (A) at least one monomer which is an end-capped polyarylene polyether having the formula: Z f polyarylene polyether chain ) Z' wherein Z and Z' are each a monovalent unsaturated organo moiety, the polyarylene polyether chain being substituted or unsubstituted; and (B) at least one monomer having at least one monovalent unsaturated organo moiety. The copolymer can be prepared using any of the vinyl reactive end-capped polyarylene polyethers taught or described herein. A preferred class of copolymers which are within the scope of the invention are those wherein on monomer (B) the monovalent unsaturated organo moiety is an alkylene, aralkylene or cycloalkylene moiety. Preferably monomer (B) contains at least one reactive vinyl group R7R8C=CR9-, reactive vinylidene group R7RsC=C=C-, and/or reactive vinylene group -CR10=CR11-.

The polymerization is effectively conducted in the presence of a free radical initiator, with concurrent heat application being preferred. Polymerization can also be'effected by means of actinic radiation, such as, ultraviolet light.

DETAILED DESCRIPTION OF THE INVENTION Basically, the end-capped high molecular weight polyarylene polyether resins of the present invention are the linear thermosetting reaction products of an alkali metal double salt of a dihydric phenol and a dihalobenzenoid compound, the thermosetting resins then being end-capped with monovalent unsaturated organo compounds. Usually a residuum of a dihydric phenol and a residuum of a benzenoid compound are both valently bonded to the ether oxygen through aromatic carbon atoms One convenient method of producing the compositions having the formulae: Z --CO - E' - O - E -)-n OZ' or Z--G O - Ar )n OZ' wherein Z, zl, E, E', Ar and n are the same as defined above, is the following: Dihydric phenol, such as, 2,2-bis(4-hydroxyphenyl)propa e ("bisphenol-A"), is dissolved in a solvent such as a mixture of monochlorobenzene and dimethyl sulfoxide. The dihydric phenol is converted to the alkali metal salt by adding an alkali metal hydroxide, such as, sodium hydroxide, an alkali metal hydride, an alkali metal hydroxide, an alkali metal alkoxide or an alkali metal alkyl compound, and removing the water of condensation by azeotropic distillation. An aromatic compound having two activated halo substituents is added to the alkali metal salt. 4,4'-Dichlorodiphenyl sulfone is illustrative of such aromatic compounds. The dihalo aramatic compound is used in a controlled proportion so thatthere will be a stoichiometric excess of the alkali metal salt. The dihalo aromatic compound and the alkali metal salt are reacted to form a linear polyarylene-polyether chain having alkali metal salt end groups. This compound is then reacted with an appropriate end-capping agent, such as, allyl chloride, to form a monovalent unsaturated organo end-capped polyarylene-polyether, which is recovered by coagulating the solution in anhydrous methanol or anhydrous isopropyl alcohol. The dihydric phenol used can be a mononuclear compound such as hydroquinone or resorcinol, which may be substituted with an inert substituent such as alkyl, alkoxy or halo (with the allyl having 1 to 4 carbon atoms). In the case of hydroquinone and the like, a process using K2CO3 in dimethylacetamide is used wherein the monomers (hydroquinone, 4,4'-dichlorodiphenyl sulfone and K2CO3) are charged into the dimethylacetamide (sulfolane is also useful), and the water of reaction is removed azeotropically with toluene or the like. The dihydric phenol can also be a polynuclear phenol. Examples of polynuclear phenols are p,p-biphenol, naphthalene diol, alkane bisphenols such as bis(4-hydroxyphenyl)methane and 2,2-bis(4-hydroxyphenyl) propane, bisphenol sulfones such as bis(4-hydroxyphenyl) sulfone, the bisphenol sulfides such as bis(4-hydroxyphenyl) sulfide, the bisphenol ethers such as bis(4-hydroxyphenyl) ether, and the bisphenol ketones such as bis(4-hydroxyphenyl) ketone. The preferred dihydric phenols are hydroquinone, bisphenol-A, p,p'-biphenol and tbis(4-hydroxyphenyl) sulfone. The second class of compounds used are aromatic compounds that have two activated halo substitutents. The halo substituents are activated so that, in the absence of a catalyst, the aromatic compound can react with alkali metal phenoxide to form an ether. As is well known in the art, one way to activate the halo substituents is to have an inert electron withdrawing group ortho or para to the two halo groups. The halo-substituted aromatic compound can be a mononuclear compound, such as, 1,2 4,5-tetrabromobenzene, 1,2,4,5-t'etrachlorobenzene, 2,4- and 2,6-dichlorobenzonitrile, hexachlorobenzene and 1,4-dibromo 2,3,5,6rtetrachlorobenzene, or a polynuclear compound, such as, 4,4 '-dichlorodiphenyl sulfone, 4,4 '-bis(4-chlorophenylsulfonyl) biphenyl, 4,4 '-dichlorodiphenyl ketone, 3,4,5,3', 4',5'-hexachlorobiphenyl and 4,4'-dibromo-3,5,3',5' - tetrachlorobiphenyl. Other useful and illustrative dihydric phenols and aromatiC compounds that contain two activated halo substituents are disclosed in U. S. Patent Nos. 3,539,656, 3,539,657, 3,355,272, 3,634,354, 3,928,295 and 3,764,583, the pertinent portions of which are incorporated herein by reference. The foregoing outline of a process for producing the above-identified compositions can be represented by the sequencef of reaction steps presented below in which HO-E-OH represents the dihydric phenol and Cl-E'-Cl represents the dihalo aromatic compound: EMI13.1 In it the above sequence of reaction steps (1), (2)and (3), the dihydric phenol is preferably employed in a stoichiometri excess over the dihalo aromatic compound. Preferably from about 1.02 to about 1.16 moles of dihydric phenol is employed per mole of the dihalo aromatic compound. Within this range of properties, the reduced viscosities in chloroform at 250C. an at a concentration of 0.2 gram of polymer per 100 milliliters of solution, of the polyarylene polyethers and the end-capped polymers derived therefrom, usually will be within the range of from about 0.1 to axt 0.5 (ll/g. (Reduced viscosity is determined by the procedure of ASTM-D-2857.) Proportions outside this range can also he used in some cases when it is desired to produce end-capped polymers of either higher or lower mole cular weights. (dg/g means deciliter per gram.) The above sequence of reaction steps (1), (2) and (3) is the most convenient way to produce the above-identified compositions. However, variations of the procedure are well within the skill of the art and are contemplated by this invention. For instance, reaction step (2) can be carried out with an excess of the dihalo compound (thepreferred proportion of stoichiometric excess being the same as that given above for the dihydric phenol), followed by an alkaline hydrolysis reaction to convert the halo substituent to alkali metal phenoxide. Then, after azeotropic removal of water, the product is subjected to reaction step (3). Alternatively, the "single salt process" can be employed (e.g. as described in British Patent No. 1,369,156) to produce a polyarylene polyether terminated at one end by a halo substituent and at the other by alkali metal phenoxide. Upon alkaline hydrolysis of the halo group, followed by dehydration, the product can then be subjected to Reaction (3), as described herein. In the first step, that is, reaction step (1), the dihydric phenol is converted to the corresponding alkali meta salt. Two moles of alkali metal hydroxide, such as sodium hydroxide or potassium hydroxide, are reacted per mole of dihydric phenol. Almost exactly stoichiometric quantities should be used. This reaction is carried out in a solvent system that permits azeotropic removal of the water of condensation. A mixture of monochlorobenzene (MCB) and dimethyl sulfoxide (DMSO) is excellent for this purpose The DMSO isused as the solvent, and MCB is an azeotroping agent. Other useful solvents include dimethylacetamide (DMAC), and other useful azeotroping agents include chlorinated benzenes, benzene, toluene, and xylene. The condensation reaction to produce th alkali metal phenoxide normally is conducted from about 120 to about 240 minutes at a temperature of from about 1100 to about 1320C. While a much broader temperature range can be used the above one is the most convenient. After the water of condensation has been removed azeotropically, the dihalo aromatic compound is added to the reaction mixture to carry out reaction step (2). This reaction is carried out at an elevated temperature, for example, from about 1500C to about 1700C., for a period of from about 60 to about 120 minutes. Upon completion of reaction step (2), a polyarylene polyether having alkali metal phenoxide end groups is produced. This composition is reacted with a monovalent unsaturated organo compound to produce the end-capped polyarylene polyether resins of the invention. Generally the monovalent unsaturated organo moiety is - selected from the group consisting of: EMI15.1 EMI16.1 wherein R1, R2 and R3 each is hydrogen, an aliphatic hydrocarbon radical containing 1 to 20 carbon atcms,an alicyclic hydrocarbon radical containing I to 20 carbon atoms or an aromatic radica and R4, R5 and R6 each is a diva lent alkylene radical containing 1 to 20 carbon atoms, a divalent arylene radical containing 6 to 10 carbon atoms or a divalent cycloalkylene radical containing 3 to 8 carbon atoms. Preferably R11 R2 and R3 each is hydrogen, an alkyl radical having 1 to 8 carbon atoms, an aryl radical, an aralkyl radical, an alicyclic radical having 3 to 8 carbon atoms or a bicyclic radical. Preferably R4, R5 and R6 each a divalent alkylene radical having 1 to 8 carbon atoms. Typical aromatic radicals are benzyl, phenyl and naphthyl. Typical alkyl radicals are methyl, ethyl, 2-propyl, l-propyl, 1-butyl 2-methyl-l-propyl, 2-butyl, l-pentyl, 3-metyl-l-butyl, 2-pent 1, 3-pentyl, 3-methyl-2-butyl, l-hexyl, 2-ethyl-1-butyl, 2-methyl-lpentyl, 3-methyl- 1-pentyl, 2, 3-dimethyl- l-butyl, 3-methyl-2pentyl, 4-methyl-2-pentyl, 2,3-dimethyl-2-butyl, l-heptyl, 2,4-dimethyl-3-pentyl, l-octyl, 2-octyl, l-dodecyl, 1-octadecyl and 1-hexadecyl. Examples of aromatic radicals are benzyl, methyl benzyl, o-, m- and p-dimethylbenzyl, ethylbenzyl, trimethyl benzyl, n-propylbenzyl and isopropylbenzyl.Exaxples of alicyclic and bialicyclic radicals are cyclobutyl, cyclopropyl methyl, cyclopropyl, cyclopentyl, cyclopentyl methyl, cyclohexyl, cyclohexyl methyl and cyclooctyl. Examples of divalent alkylene radicals are -CH2-, -CH2CH2-, -(CH2)3-, -(CH2) ' EMI17.1 and -(CH2)12-. Examples of divalent arylene radicals are -C H - (o, m and p), and -C10H6-. Examples of diva lent cycloalkylene radicals are EMI17.2 The preferred halide end-capping agents are allyl chloride, 2-chloroethylacrylate, 2-chloroethylmethacrylate, chloromethyldimethylvinylsilane, vinyl benzyl chloride and 2-chloroethyl vinyl ether. Examples of useful halides for end-capping are; allyl chloride (CH2=CH-CH2C1), allyl fluoride, allyl bromide, l-propenyl chloride (CH3CH=CHCl), l-propenyl fluoride, 1-propenyl bromide, CH3CH=CHCH2Cl, CH2=CHCH2CH2Cl, 2 CH C CH3CH=CHCH2CH2Cl, CH2=C(CH3)CH2CH2Cl, CH2=CHCH2CH2CH2CH2Cl, vinyl benzyl chloride, vinyl benzyl floride, vinyl benzyl bromide, 3-phenylpropenyl chloride, EMI17.3 The thermoplastic polyarylene polyethers are rendered "cross-linkable" through the incorporation of unsaturated moieties. This is accomplished conveniently by replacing saturated agents, such as, methyl chloride, an endcapping reagent, with an unsaturated reagent. The resulting resins contain unsaturated group at the chain ends. The composition is cross-linkable in the presence of a suitable free radical initiator. Upon curing these end-capped polysulfone compositions have been shown to provide improved stress-cracking resistance and better adhesive properties. They are also useful for various polymer modification purposes particularly as a "rigid block" in forming block and graft copolymers. The The end-capping reaction, i.e., reaction step (3), is carried out by reacting the monovalentunsubstituted organo compound with the alkali metal phenoxide-capped polyarylene polyether resin produced by reaction step (2). The stoichiometric proportions aware two moles of unsubstituted organo compound per mole of polyarylene polyester resin. It is preferred to employ about a 2 to 10 mole percent stoichiometric excess of the unsubstituted organo compound. The reaction mixture preferably should be substantially anhydrous. The reaction medium can be the same solvent system that was employed for reaction steps (1) and (2). The reaction is carried out at elevated temperatures, e.g., at from about 1100C. to about 165 C. At the recommended temperature range, the reaction will usually take from about 10 to about 90 minutes. The completion of the reaction can be detected by treating a sample of the reaction mixture with bromocresol purple indicator. When the alkali metal phenoxide has reacted, the treated sample will b greenish yellow in color. At the completion of the reaction, the reaction mixture can be cooled, filtered to remove salt by-product, and then the end-capped polyarylene polyether resin can be recovered b coagulation in a non-solvent for the resin, e.g., methanol or isopropyl alcohol. Preferably the reaction mixture and th resin is kept anhydrous until the resin has ben recovered as a solid. The substantially equimolar one-step reaction of a double alkali metal salt of a dihydric phenol with a dihalobenzenoid compound is done in the presence, for example, of specific liquid organic sulfoxide or sulfone solvents unde substantially anhydrous conditions. Catalysts are not necessary for this reaction. Another feature of the invention involves simultanequsly contacting substantially equimolar amounts of an alkali metal double salt of a dihydric phenol and a dihalobenzenoid compound with a solvent mixture comprising an azeotrope former and a sulfoxide or sulfone reaction' solvent in a weight ratio of from about 10:1 to about 1:1, preferably from about 4:1 to about 3:1, removing water from the reaction mass as an azeotrope with the azeotrope former until substantially anhydrous conditions are attained, adjusting th ratio of azeotrope former to reaction solvent from about 1:1 to abort 1:10, preferably from about 1:3 to about 1:4, by removing excess azeotrope former, and reacting the alkali metal double salt with the dihalobenzenoid compound in the liquid phase of the sulfoxide or sulfone reaction solvent. The useful sulfoxide or sulfone solvents are those of the formula: R-S(O)V-R wherein each R represents a monovalent lower hydrocarbon grou free of aliphatic unsaturation of the alpha carbon atom, and preferably contains less than about 8 carbon atoms or when connected together represents a divalent alkylene group with v being an integer from 1 to 2 inclusive. Thus, in all of thes solvents all oxygens and two carbon atoms are bonded directly to the sulfur atom. Thus, contemplated for use in the invention are such solvents as those having the formula: EMI20.1 wherein the R groups are lower alkyl, such as methyl, ethyl, propyl, butyl and like groups and aryl groups such as phenyl and alkyl phenyl groups as well as those where the R groups are interconnected as in a divalent alkylene bridge, such as: EMI20.2 as in.thiophene oxides and dioxides. Specifically mentionabld of these solvents but by no means exhaustive of these solvent are dimethylsulfoxide, dimethylsulfone, diethylsulfoxide, diethylsulfone, diisopropylsulfone, tetrahydrothiophene 1,1dioxide (commonly called tetramethylene sulfone or sulfolane) and tetrahydrothiophene-l monooxide. The diethylsulfoxide has been found to be the most useful as the solvent for this reaction because it is a solvent for the widest variety of reactants as well as for the resulting polymer of the reaction. Aliphatic unsaturation on the alpha-carbon atom, such as occurs in divinyl sulfone and sulfoxide, should not be present as such materials tend to be reactive and polymerize under the conditions of this reaction. However, unsaturation on a beta-carbon ato or one further removed from the sulfur atom can be tolerated and such solvents can be employed in this reaction. In situations where it is desired to prepare the alkali metal salt of the dihydric phenol in situ in the reaction solvent, the dihydric phenol and an alkali metal hydroxide ar admixed in essentially stoichiometric amounts and normal precautions taken to remove all the water of neutralization preferably by distillation of a water-containing azeotrope fram the solvent-metal salt mixture. It has been convenient to employ benzene, xylene, halogenated benzenes or other inert organic azeotrope-forming organic liquids in performing this. Heating the alkali metal hydroxide, dihydric phenol and small amounts of the azeotrope former to reflux for several hours while removing the azeotrope is the most desirable. However, it is obvious that any other technique for removing essentially all of the water can be equally satisfactory. It is not essential and critical in this reaction that all of the azeotropic former be removed before the reaction of the alkali metal salt of the,bisphenol with the dihalobenzenoid compound. In fact, it is desirable in some instances to employ an amount of such material in excess of that needed to azeotrope off all of the water, with the balance being used as a co-solvent or inert diluent with the sfllfone or sulfoxide principal solvent. Thus, for instance, benzene, heptane, xylene, toluene, chlorobenzene, dichlorobenzene or like inert liquids can be beneficially employed. The azeotrope former can be one either miscible or immiscible with the sulfone or sulfoxide major solvent. If it is not miscible it should be one which will not cause Precipitation of the polymer in the reaction mass. Heptane is such a solvent. When employed, it will merely remain inert and immiscible in the reaction mass. If the azeotrope former would cause precipitation of the polymer, it should be remove ;almost completely from the reaction mass before initiating polymerization. For such reasons, it is preferred to employ azeotrope formers which are miscible with the major solvents and which also act as co-solvents for polymer during polymer zation. Chlorobenzene, dichlorobenzene and xylene are azeotrope formers of this class. Preferably the azeotrope former should be one boiling below the decamposition temperature 5Of the major solvent and be perfectly stable and inert in the process, particularly inert to the alkali metal hydroxide when the alkali metal salt of the dihydric phenol is prepared in situ in the presence of the inert diluent or azeotrope former. It has been found that chlorobenzene and o-dichlorobenzene serve particularly well as the inert diluent and are able to significantly reduce the amount of the sulfone or sulfoxide solvent necessary. The co-solvent mixture using even as much as 50 percent of the halogenated benzene with dimethylsulfoxide, for example, not only permits the formed polymer to remain in solution and thus produce hig bimolecular weight polymers, but also provides a very economics processing system, and an effective dehydration operation. Any of the alkali metal hydroxides can be employed in this technique, that is to say any alkali metal salt of the dihydric phenol can be used as the one reactant. Potassium and cesium salts have been found to react considerably faster than the sodium salts, but due to expense of the cesium salts the potassium salts are preferred. As heretofore indicated, the alkali metal salt should, of course, be the double metal salt, i.e,, both aromatic hydroxyl groups being saponified, i order to prepare these products. Single metal salts ordinarily limit the molecular weight of the product. While this may be desirable as a chain terminator or molecular weight regulator near the terminus of the reaction period, the initial reactio and the major portion thereof should be with the double alkal metal salt of the dihydric phenol. The alkali metal moieties of this compound however can be the same or different alkali metals. Substantially equimolar amounts of the alkali metal double salt of a dihydric phenol (or a dihydric phenol for in situ conversion to the salt) and a dihalobenzenoid compound are simultaneously contacted with a solvent mixture comprising an azeotrope former and a sulfoxide or sulfone reaction solvent in a ratio of from about 10:1 to about 1:1 by weight based on the combined weight of the azeotrope former and reaction solvent. When water is present in this solvent mixture, a phase separation occurs even between normally miscible liquids creating two liquid phases. When this phase separation occur the water and hydrated alkali metal double salt of a dihydric phenol are preferentially dissolved in the sulfoxide or sulfone reaction solvent phase and the dihalobenzenoid compound is preferentially dissolved in the azeotrope former phase. The initial ratio of azeotrope former to reaction solvent is critical in this respect because with lesser amounts of azeotrope former, two liquid phases are not formed and undesirable hydrolysis of the dihalobenzenoid compound occurs. Only When the ratios specified are used does a phase separation occur which isolates the dihalobenzenoid compound from hydrolysis by the water in the system. If dry crystalline alkali metal salt of a dihydric phenol is employed, problems relative to obtaining anhydrous conditions are essentially avoided. However, drying the salt and keeping it dry during transfer and charging is difficult. It is more advantageous to employ a hydrated alkali metal salt which is dehydrated in the reaction mass by removing the water of hydration. Water then can be present or formed in the reaction mass as the water of hydration of a hydrated alkali metal salt, as the water of neutralization formed during the in situ conversion of a dihydric phenol to the alkali metal double salt, or as water present in either the azeotrope former or the reaction solvent. During the in situ conversion, the hydrated salt is formed first which is then dehydrated upon the removal of water. When the two liquid phases are formed, it is important that the water in the system be removed as quickly as possible, usually by refluxing the mixture at about the boiling point of the azeotrope former until substantially all of the water is removed. During the water removal, the dehydrated alkali metal double salt, which is insoluble in the reaction solvent at the reflux temperatures, precipitates. The fact that all the'waster has been removed is usually signaled by no further precipitate formation, no further azeotrope formation, and the formation of one liquid phase when miscible liquids are used. After the water has been removed, excess azeotrope former is removed by distillation until the ratio of azeotrop former to sulfoxide or sulfone reaction solvent is about 1:1 to 1:10. Only when the amount of azeotrope former is reduced to within these ratios, does significant polymerization occur The residuum of the dihydric phenol of these alkali metal salts is not narrowly critical. It can be,for instance, a mononuclear phenylene group as results from hydroquinone and resorcinol, or it may be a di- or polynuclear residuum. Likewise the residuum be substituted with other' inert nuclear substituents such as halogen, alkyl, alkoxy and like inert substituents. From a practical standpoint, limitations on polymer molecular weights can be expected when the dihydric phenol or the alkali metal derivative thereof contain strong electron withdrawing groups. This may result in lower molecular weigh polymers or impractically slow reaction rates. Hence, the dihydric phenol should be a weakly acidic dinuclear phenol, such as, the hydroxy diphenyl alkanes or the nuclear halogenated derivatives thereof, such as, the 2,2- bis (4-hydro xyphenyl) propane, 1, 1-bis (4-hydroxyphenyl) 2-phenyl ethane, bis(4-hydroxyphenyl)methane, or the chlorinated derivatives containing one or two chlorines on each aromatic ring. While these halogenated bisphenolic alkanes are more acidic than the non-halogenated bisphenols and hence slower in reactivityX in this process, they do impart valuable flame resistance to these polymers. Other materials also termed appropriately "bisphenols" are also highly valuable and preferred. These materials are the bisphenols of a symmetrical or unsymmetrica joining group, as, for example, ether oxygen (-0-), carbonyl EMI26.1 sulfide (-S-), sulfone EMI26.2 or hydrocarbon 5residue in which the two phenolic nuclei are joined to the same or different carbon atoms of the residue such as, for example, the bisphenol of acetophenone, the bisphenol of benzophenone, the bisphenol of vinyl cyclohexene, the bisphenol of alpha-pinene, and the like bisphenols where the hydroxyphenyl groups are bound to the same or different carboy atoms of an organic linking group. rbo Such dinuclear phenols can be characterized as having the structure: : EMI26.3 wherein Ar is an aromatic group and preferably is a phenylene group, Y and Y1 can be the same or different inert substituen 3groups as alkyl groups having from I to 4 carbon atoms, halogen atoms, i.e., fluorine, chlorine, bromine or iodine, o alkoxy radicals having from 1 to 4 carbon atoms, m and z are integers having a value from 0 to 4, inclusive, and R is representative of a bond between aromatic carbon atoms as in dihydroxydiphenyl, or is a bivalent radical, including for example inorganic radicals as EMI27.1 -0-, -S-, -S-S-, 'S02-' and divalent organic hydrocarbon radicals such as alkylene, alkylidene, cycloaliphatic, or the halogen, alkyl,aryl or like substituted alkylene, alkylidene and cycloaliphatic radicals as well as alkalicyclic, alkarylene and aromatic radicals and a ring fused to'both Ar groups. Examples of specific substituted dihydric polynuclear phenols include among others: the substituted bis-(hydroxylphenyl) alkanes, such as, 2,2-bis-(4-hydroxyphenyl)propane, 2,4 '-dihydroxydiphenyl methane, bis-(2-hydroxyphenyl)methane, bis- (4-hydroxyphenyl)methane, bis(4-hydroxy-2,6-dimethyl-3 methoxyphenyl)methane, l,l-bis-(4-hydroxyphenyl)ethane, 1,2-bis-(4-hydroxyphenyl)ethane, 1, 1-bis (4-hydroxy-2-chlor- phenyl)ethane, 1,1-bis- (3-methyl-4-hydroxyphenyl) propane, 1,3-bis-(3-methyl-4-hydroxyphenyl)propane, 2,2-bis-(3-phenyl-4hydroxyphenyl)propane, 2,2-bis-(3-isopropyl-4-hydroxyphenyl)propane, 2,2-bis-(2-isopropyl-4-hydroxyphenyl)propane,2,2-bis (4-hydroxynaphthyl)propane, 2,2-bis-(4-hydroxyphenyl)pentane, 3,3-bis-(4-hydroxyphenyl)pentane, 2,2-bis-(4-hydroxyphenyl)heptane, bis-(4-hydroxyphenyl)phenylmethane, 2,2-bis-(4-hydroxy phenyl)-l-phenylpropane, 2, 2-bis- (4-hydroxyphenyl) 1,1,1,3,3,3,- hexafluoropropane and the like; the substituted di(hydroxyphenyl)sulfones, such as, bis-(4-hydroxyphenyl)-sulfone, 2,4' -dihydroxydiphenyl sulfone, 5'-chloro-2,4'-dihydroxydiphenyl sulfone, 5'-chloro-4,4'-dihydroxydiphenyl sulfone and the like; and the substituted di(hydroxyphenyl)ethers, such as, bis-(4- hydroxyphenyl)ether, the 4,3-, 4,2'-, 2,2'- and 2,3' hydroxy- diphenyl ethers, 4,4'-dihydroxy-2,6-dimethyldiphenyl ether, bis-(4-hydroxy-3-isobutylphenyl)ether, bis- (4-hydroxy-3-iso- propylphenyl)ether, bis-(4-hydroxy-3-chlorophenyl)ether, bis-(4-hydroxy-3-fluorophenyl)ether, bis-(4-hydroxy-3-bromophenyl)ether, bis-(4-hydrbxynaphthyl)ether, bis-(4-hydroxy 3-chloronapthyl)ether, 4,4'-dihydroxyl-3,6-dimethyoxydiphenyl ether, 4,4'-dihydroxy-2,5-diethoxydiphenyl ether and the like In the invention a mixturewof two or more different dihydric phenols can be used. Thus, herein the -E- or -E'residuum in the polymer structure can actually be the same or different aromatic residue. As herein used the term E or E' when defined as being the "residuum of the dihydric phenol" of course refers to the residue of the dihydric phenol after the removal of the two aromatic hydroxyl groups. Thus as is readily seen these polyarylene polyethers contain recurrding groups of the residuum of the dihydric phenol and the residuum of the benzenoid compound bonded through aromatic ether oxygen atoms Any dihalobenzenoid compound or mixture of dihalobenzenoid compounds can be employed in the invention which compound or compounds has the two halogens bonded to benzene rings having an electron withdrawing group in at least one of the positions ortho and para to the halogen group. The dihalobenzenoid compound can be either mononuclear where the halogens are attached to the same benzenoid ring or poly nuclear where they are attached to different benzenoid rings, as long as there is an activating electron withdrawing group in the ortho or para position of that benzenoid nucleus. Any of the halogens may be the reactive halogen substituents on the benzenoid compounds. Fluorine and chlorine substituted benzenoid reactants are preferred; the fluorine compounds for fast reactivity and the chlorine compounds for their inexpensiveness. Pluorine substituted benzenoid compounds are most preferred, particularly when there is a trace of water presen in the polymerization reaction system. However, this water content should be maintained below about 1 percent and prefer ably below 0.5 percent for best results. Any electron withdrawing group can be employed as the activator group in these compounds. It should be, of course, inert to the reaction, but otherwise its structure is not critical. Preferred are the strong activating groups such as the sulfone group EMI29.1 bonding two halogen substituted benzenoid nuclei as in the 4,41-dichlorodiphenyl sulfone and 4,4'-diflu orodiphenyl sulfone, although such other strong withdrawing groups can also be used. The more powerful of the electron withdrawiag groups give the fastest reactions and hence are preferred. It is further preferred that the ring contain no electron supplying groups on the same benzenoid nucleus as the halogen; however, the presence of other groups on the nucleus or in the residuum of the compound can be tolerated. Preferably, all of the substituents on thebenzenoid nucleus are either hydrogen (zero electron withdrawing), or other groups having a positive sigma value [as set forth in J. F. Bunnett, Chem. Rev. 49,273 (1951), and Quart. Rev., 12, 1 (1958)].The electron withdrawing group of the dihalobenzenoid compound can function either through the resonance of the aromatic ring, as indicated by those groups having a high sigma value, i.e., above about +0.7, or by induction as in perfluoro compounds and like electron sinks. - Preferably the activating group should have a high sigma value, preferably above 1.0, although sufficient activity to promote the reaction is evidence in those groups haying a sigma value above 0.7, although the reaction rate with such a low powered electron withdrawing group may be somewhat low. The activating group can be basically either of two types: (a) monovalent groups that activate one or more halogens on the same ring as a nitro group, phenylsulfone, or alkylsulfone, cyano, trifluoromethyl, nitroso, and hetero I nitrogen as in pyridine; or (b) divalent group which can activate displacement of halogens on two different-rings, such as the sulfone group EMI30.1 <tb> <SEP> 0 <SEP> O <SEP> H <tb> <SEP> n <SEP> n <SEP> I <tb> -S-; <SEP> the <SEP> carbonyl <SEP> group <SEP> -C-; <SEP> the <SEP> vinyl <SEP> group <SEP> -C=C-; <SEP> the <tb> <SEP> H <tb> <SEP> n <SEP> H <tb> sulfoxide <SEP> group <SEP> -S-; <SEP> the <SEP> amo-group <SEP> -N=N; <SEP> the <SEP> saturated <SEP> O <tb> a <tb> fluorocarbon <SEP> groups <SEP> -CF2CF2-; <SEP> organic <SEP> phosphine <SEP> oxides <SEP> -P-; <tb> <SEP> R <tb> wherein R is a hydrocarbon group, and the ethylidene group EMI31.1 where X can be hydrogen or halogen or which can activated halogens on the same ring such as with difluorobenzoquinone, 1,4- or 1,5- or 1,8-difluoroanthraquinone. A plurality of electron withdrawing groups can be employed if desired, including electron withdrawing groups having a sigma value below about +0.7, provided the cumulative sigma influence on each of the reactive halogen groups of the halobenzenoid compound is at least about +0.7. If desired, the polymers may be made with mixtures of two or more dihalobenzenoid compounds each of which has this structure, and which may have different electron withdrawing groups. As used herein, the term E or E' when defined as being the "residuum of the benzenoid compounds refers to the aromatic or benzenoid residue of the compound after the removal of the halogen atoms on the benzenoid nucleus. Dimethylsulfoxide decomposes at its boiling point, i.e. about 1890C.; it is desirable to keep the reaction temperatur below this to avoid such problems when employing this solvent The reaction temperature can be effectively increased even above the normal boiling point of the solvent or mixture of solvents by the use of pressure in the system. However, for most practical reactions contemplated herein, atmospheric pressures are quite adequate, though if desired pressures as high as 1000 psig or more can be employed. The molecular weight of the polymer can be easily controlled in this process by the addition of a precipitating solvent to the reaction mixture when the desired reduced viscosity of the resin is secured or when the indicated viscosity of the polymerization mass is high enough to indicate the desired molecular weights are achieved. It is also possible to terminate the growing polymer chain by the addition of a monofunctional chain stopper, such as an alkyl halide or other suitable coreactant. The molecular weight of the end-capped resins is indicated by reduced viscosity in indicated solvents. The viscosity of a resin solution bears adirect relationship to the weight average molecular size of the resin chains, and can be used to characterize the degree of polymerization. The reduced viscosity values used herein are of significance only relative fo each other rather than in any''absolute sense, and for this reason other polyether-solvent systems can be employed as an indication of the relative molecular weight of these resins. When solvents other than chloroform are employed, the required average molecular size relationshi can readily be established by reference to the reduced viscosity values defined herein even though the numerical reduced viscosity,values of the alternative system may be different. In the in situ process (conversion) the preferred solvent is dimethylacetamide; the process uses K2CO3. The preferred class of end-capped thermosetting resins of the invention are those polysulfone where the thermosetting polyarylene polyether resin is composed of recurring units having the formula: EMI33.1 wherein R is hydrogen, lower alkyl, lower aryl and halogen substituted lower alkyl and lower aryl-groups. Most preferably R is methyl. The lower alkyl groups have from 1 to 4 carbon atoms. As used herein, the polysulfone-vinyl reactive resins or PSF-VR are the above end-capped resins when R is methyl an the end-capping moieties are alkylene, aralkylene or cycloalkylene moieties. Also as used herein, the (prior art) polysulfone-silane reactive resins or PSF-SR refer to silane end-capped polyaryl ene polyether polymers made from bisphenol-A and dihalodiphenylsulfone. (See U. S. Patent No. 4,093,600 and 4,183,874 2 Because of their thermoset nature, the cured polysulfonevinyl reactive resins exhibit a markedly improved environmental stress-crack resistance and a better dimensional stabilit at elevated temperatures than those of the thermoplastic polysulfone. The polysulfone-vinyl reactive resin is prepared by a two step process, namely, polymerization followed by endcapping. In the polymerization step, bisphenol A and dihalo5diphenylsulfone are polymerized in the presence of an alkali metal hydroxide, an alkali metal oxide and/or ammonium hydroxide. A deficient amount of sulfone monomer is used during the polymerization to produce the desired sodium phenate terminated oligomers. By varying the sulfone monomer/bisphenol A charge ratio, polysulfone-vinyl reactive resin of a wide range of molecular weights can be prepared. The sequence of reactions of the preparation process of the invention is represented schematically below wherein the end-capping reagent is vinyl benzyl chloride: SCHEMATIC PRESENTATION OF POLYSULFONE-VINYL REACTIVE PREPARATION EMI35.1 <SEP> CH3 <tb> <SEP> # <tb> HO-#-C-#-OH <SEP> + <SEP> Cl-#-SO2-#-Cl <tb> <SEP> # <tb> <SEP> CH3 <tb> <SEP> Polymerization <SEP> NaOH <tb> <SEP> CH3 <SEP> CH3 <tb> <SEP> # <SEP> # <tb> NaO-#-C-#-O-#-SO2-#-O-#-C-#n-ONa <tb> <SEP> # <SEP> # <tb> <SEP> CH3 <SEP> CH3 <tb> <SEP> End-Capping <SEP> ClCH2-#-CH2=CH2 <tb> <SEP> CH3 <SEP> CH3 <tb> <SEP> # <SEP> # <tb> CH2=CH-#-CH2-O-#-C-#-O-#-SO2-#-O-#-C-#-O-CH2-#-CH=CH2 <tb> <SEP> # <SEP> # <tb> <SEP> CH3 <SEP> CH3 <tb> POLYSULFONE-VINYL REACTIVE RESIN In the polymerization step, the preferred alkali metal hydroxide is sodium hydroxide. useful alkali metal hydroxid include lithium hydroxide, potassium hydroxide, rubidium e1 hydroxide and cesium hydroxide. Useful alkali metal oxides include sodium oxide, lithium oxide, potassium oxide, rubidiu oxide and cesium hydroxide. Ammonium hydroxide is also usefu in the polymerization step in place of the sodium hydroxide. The polymerization step is carried out at a temperatur preferablyetween 163 and 1659C. in a mixed solvent compose of dimethyl sulfoxide (DMSO) and monochlorobenzene (MCB), although any other suitable solvent(s) such as dimethyl acetamide (DMAC) can also be employed. Any suitable polymers zation temperature (e.g., 1200 to 18500.) can be used. Precautions which are normally observed during the preparation of standard polysulfone are equally important here to achieved quality products. Of particular importance is the caustic charge which affects both the-"color" and "stability" of the finished polysulfone-yinyl reactive resin in addition to its anticipated effect on the molecular weight and composition of the latter. Useful polar solvents include: alcohols, such as, methanol, ethanol, n-propyl alcohol, n-butyl alcohol, amyl alcohol, isopropyl alcohol, sec-butyl alcohol, isobutyl alcohol and 4-methyl 2-pentanol; ethers, such as ethyl ether, diethyl Cellosolve and butyl ether; aldehydes, such as benzaldehyde and furfural; triethyl phosphate; and amides, such as, N,N-dimethyl formamide, acetamide and butramide. In the end-capping or terminating step, the alkali oxy (e.g., NaO-) end groups of the polysulfone are reacted with a halo organo compound containing a terminal or near terminal unsaturated group. The compounds used for end-capping or terminating are halogenated, unsaturated compounds. The end-capping reagents are described by the generic formula xzwhere in X is a halogen, preferably chlorine, and Z is an unsaturated organic radical. More specifically, Z is usually a reactive, unsaturatedradical having an alkylene, aralkylen or cycloalkylene moiety (linked to the halogen). Most halophenyl compounds have limited reactivity. Examples of the preferred end-capping reagents are ally chloride, 2-chloroethylacrylate, 2-chloroethylmethacrylate, chloromethyldimethylvinylsilane, vinyl benzyl chloride and 2-chloroethyl vinyl ether. The halo organo compound reacts like an alkyl halogen with the alkali oxy end groups. Although end-capping is preferably done at a temperature of 1150 to 12O0C., no deleterious effect was usually evident even when the end-capping was performed at the preferred polymerization temperature which i from 1630 to 1650C. Because of a much greater reaction rate at the latter temperature, the required reaction time is shortened drastically. Apparently a more complete reaction also results at the high temperature levels due to lower viscosities. Any suitable temperature can be used in the end capping step. Preferably anhydrous condition during the end-capping stage, coupled with a reasonably good hydrolytic stability of the halo organo compound, is used whereby premature gelation of the polysulfone-vinyl reactive resin is normally not a problem in the reactor. Upon completion of the end-capping step, the reaction mixture should be neutral which can be )readily diluted with dry monochlorobenzene (or other suitable solvent) and filtered without difficulty. However, the presence of residual alkalinity, which may resultfrom either a deficiency in end-capping reagent charged or an incompletion in reaction, can cause problems during subsequent filtering when the polymer solution is exposed to either atmospheric moisture and/or wet diluent. For this reason a speedy product recovery is recommended whenever the above circumstance is present or suspectea. The preferred (average) molecular weight of the polysulfone-vinyl reactive resin is between 5,000 and 15,000, 'although higher and lower molecular weights are within the scope of the invention. The polysulfone-vinyl reactive resin can range in size from oligomer to polymer. The average molecular weight of the polysulfone-vinyl reactive resin can be determined by the NMR technique. The polysulfone-vinyl reactive resin can be separated or recovered from the reaction mixture by any appropriate 5method, but the coagulation method and the melt recovery process are preferred. Recovery by coagulation is normally done in isopropanol (or methanol). The melt recovery production process involves removing the solvents by passing the polymer solution through a recovery system consisting of a concentrator, a devolatilizer and a Marshall mill. While polysulfone-silane reactive resins are outside of the scope of the invention, they are frequently used herein for comparitive purposes. The polysulfone-silane reactive resins are structurally very similar to the polysulfone-vinyl reactive resins of the invention, except for the end-capping by reaction with silane groups such as 3-chloropropyltrimethoxysilane. The production process is yery similar for the two types of end-capped polysulfones. The polysulfone-silane reactive resins have been prepared in a broad range of molecular weights by varying the monomer feed ratio in the synthesis of the oligomers. The polysulfone ,¯ silane reactive resins have excellent hydrolytic stability in bulk form below their glass transition temperature. They can even be suspended in water without premature gelation. Cross-linking occurs readily above the glass transition temperature, and the cure rate can be further increased by prehydrolysis of the silylalkoxy end groups or by the use of catalysts. Cross-linked polysulfone-silane reactive resins have mechanical and electrical properties comparable to those of standard polysulfone. Cured polysulfone-silane reactive may enable higher use temperature limits than thermoplastic polysulfone resins, and large improvements over such thermoplastic polysulfone resins are found in their solvent resistance (environmental stress crack resistance). Also, due to the silane end groups, a built-in bonding capability exists towards many inorganic and metallic surfaces. Concerning the polysulfone-vinyl resins in Table IV below, there was not any evidence of thermally initiated polymerization of the reactive end groups during the endcapping step. Preferably, however, the reaction temperature is kept below 1250C. during the end-capping step and the system is kept under positive nitrogen pressure throughout. Due to the absence of moisture sensitive end groups, the polysulfone-vinyl reactive resins are usually easier to handle than polysulfone-silane reactive resins during prepare tion. Once the end-capping reaction is complete, the polysulfone-vinyl reactive resins may be exposed to water or wet solvent without being affected. The only exceptions, however) are the polysulfone-vinyl reactive resins having methacryloxy or acryloxy end groups which are hydrolized readily by moisture. For this reason, the chloroalkyl esters of such are preferred. Unlike the polysulfone-silane reactive resin which has three reactive sites for each end-group, the end-groups of all of the polysulfone-vinyl reactive resins shown in Table I are monofunctional. This difference requires that a precise stoichiometry of the reactants be maintained in order to produce the desire curable product, that is, a completely end-capped resin. When there is either an excess amount of bisphenol A or a deficiency in caustic charge (NaOH), a lower end-capping efficiency will result. When 2-chloroethyl methacrylate (acrylate) is employed1 the occurrence of dehydrochlorination during the end-capping step becomes a possibility. An excess amount of end-capping reagent is usually added to off-set any potential loss due to side reactions. The molecular weights of the polysulfone-vinyl reactive resins are controlled by adjusting the stoichiometry of monomers in the feed. Using reduced viscosity (R.V.) as a measur of the molecular weight, the sulfone bisphenol-A molar ratios used in the feed are plotted against the deduced viscosity values of a series of vinyl benzyloxy end-capping polysulfone vinyl reactive resins in Figure 3. The other polysulfonevinyl reactive resins (not shown in Figure 3) follow roughly the same relationship. 3 Polysulfone-vinyl reactive resins are compositionally identical to the polysulfone-silane reactive resins except the end-groups. Consequently, the physical properties of the two types of resins are quite similar even though they cure by two distinctively different mechanisms. A comparison of the properties of these tWo resins is illustrated in Table I below.

(b) Polysulfone-silane reactive. (c) Dpending on the reactivity of the end groups. (d) Not counting the decomposition products from the peroxide if used. The thermal stability of the polysulfone-vinyl reactive resins apparently is much influenced by the nature of the end' groups. Resins end-capped with the methacryloxy ethoxy groups 1 were found to retain their thermoplasticity upon repeated thermal abuses at elevated temperatures, while those having the vinyl benzyloxy end groups would advance under similar conditions. This difference in behavior is consistent in the tact that, while the methacrylates are known to be fairly stable (thermally) in the absence of an initiator,the styrene monomers will undergo thermal-initiated polymerization - see W. R. Sorenson and T. W. Campbell, "Preparative Methods of Polymer Chemistry", 2nd Edition, Interscience (1968), pp. 210 and 253. The polysulfone-vinyl reactive resins are not subject to hydrolysis under normal conditions. They are therefore more tolerant of water or alkaline contaminates than the polysulfonesilane reactive resins. The polysulfone-vinyl reactive resins share the common unique feature with-the polysulfone-silane reactive resins in exhibiting excellent stability at ambient temperatures. This phenomenon has been attributed to the high glass transition temperature of the polysulfone backbone which severely restricts the mobility of the end groups. Curing of the polysulfone-vinyl reactive resins is effected, however; by heating above the glass transition temperature of polysulfone, usually in the presence of a free radical initiator. The preferred free radical initiators are the peroxides and the preferred peroxide is dicumyl peroxide. Examples 1 of useful peroxides are the dialkyl peroxides, such as, di-tbutyl peroxide, lauroyl peroxide, decanoyl peroxide, 2methyl pentanoyl peroxide, acetyl peroxide, 2, 5-dimethyl-2,5-di (t-butylperoxy-hexane and 2,5-dimethyl-2,5-di(t-butylperoxy)- hexyne-3, the diaryl peroxides, such as, benzoyl peroxide, the alkaryl peroxides, such as, dicuryl peroxide, the sulfonyl peroxides, such as acetyl cyclohexysulfonyl peroxide and acetyl sec-heptylsulfonyl peroxide, the peresters, such as, t-butyl perbenzoate, t-butyl peroxyneodecanoate, t-butyl peroxypivalate, 1,1; ;3,3-tetramethylbutyl peroxy-2-ethylhexanoate, 2 ,5-dimethy - 2,5-bis(2-ethylhexanoylperoxy)hexane, t-butyl peroxy-2-ethylhexanoate, t-butyl peroxyisobutyrate, t-butyl peroxymaleic acid, 00-t-butyl 0-isopropyl monoperoxycarbonate, 2,5-dimethyl 2,5-bis-(benzoylperoxy)hexane, t-butyl peracetate and di-t-butyl diperoxyphthalate, the peroxydicarbonates, such as, di(isopropyl) peroxydicarbonate, diisopropyl peroxydicarbonate, di (secbutyl) peroxydicarbonate, di(2-ethylhexyl) peroxydicarbonate, idicyclohexyl peroxydicarbonate and dibenyl peroxydicarbonate. The organometallic peroxides, such as, vinyl tris(t-butyl peroxy)silane, the hydroperoxides, such as, t-butyl hydroperoxide and cumyl hydroperoxide, 1,1,3,3-tetramethylbutyl hydroperoxide and 2,5-dihydroperoxy-2,5-dimethylhexane, the azo compounds, such as, 2,2'-azobis(isobutyronitrile) and 2,2'-azobis(2,4dimethylvaleronitrile). The reactivity of a polysulfone-vinyl reactive resin will vary greatly, depending on the type of end groups employed. Those having alloxy or vinyl ether ethoxy end groups react with difficulty, those terminated with either methacryloxy ethoxy or acryloxy ethoxy end groups are reactive but the presence of an initiator is usually necessary, and those with vinyl benzyloxy end groups will react upon thermal initation. A neat (pure) polysulfone-vinyl reactive resin, even with the reactive vinyl benzyloxy end groups, requires prolonged heating at temperatures above the glass transitional temperature of polysulfone to reach a high degree of crosslinking. The cure rate can be accelerated by the addition of a peroxide This approach, however, is often hampered by the lack of a suitable peroxide which will endure the high¯process temperature necessary fox these resins. At ambient temperatures, a neat polysulfone-vinyl reactive resin is not curable by either electron beam or Ut V. radiation due to a restricted molecular mobility. An important finding in the curing behavior of the polysulfone-vinyl reactive (PSF-VR) resins is that they are soluble in styrene monomer over the entire compositional range, and that the resultant polymex/comionQ > er binder system will polymerize and yield a true copolymer. The latter may be either a thermoset or thermoplastic depending on the polysulfone-vinyl reactiVe/styrene feed ratio, and the method of polymerization. Bulk polymerization usually leads to cross-linked products while solution polymerization at low polysulfone-vinyl reactive concentrations often produces soluble copolymers. A polysulfone-vinyl reactive resin/styree binder system is not only peroxide curable, it also can be cured by exposure to electron beahm or U. V. radiation in the presence of a photo-sensitizer. In the latter cases, styrene also acts as a diluent for the polysulfone-vinyl reactive resin to provide the necessary mobility at ambient tenperatures. In addition to styrene, polysulfone-vinyl reactive resins can be mixed and cured with a variety of other comonomer to produce copolymers having a broad range of thermal and mechanical properties. This approach not only permits the use of polysulfone-vinyl reactive resins for various polymer modification purposes but also provides an attractive way of reducing the cost of the resin through compounding with cheaper comonomers. Through the selection of comonomers and their loadings, it is often feasible to tailor-make formulations to fulfill the cost/performance requirements of different end-uses. Commercial comonomers which are suited for the above purpose include styrene, -methyl styrene, divinyl benzene, acrylates, methacrylates, acrylonitrile, diallylphthalates, trimethylolpropanetrimethacrylate, triallylcyanurate, c4-methacryloylpropyltrimethoxysilane and diacetone acrylamide. By employing polysulfone-vinyl reactiv resins of various initial molecular weights, polysulfone-viny reactive resin/comonomer binder systems having different crosslinking densities as well as polysulfone block lengths can be prepared. The use of a comonomer in conjunction with the polysulfone-vinyl reactive resin offers a number of advantages: (a) the formulation is rendered curable by conventional methods; (b) property modifications are permitted through a wide selection of comonomers; and (c) flexibility is allowed in meeting the cost/performance requirements for different end-use areas. Upon cross-linking, polysulfonevinyl reactive resins exhibit a marked improvement in enironmental stress-crack resistance over the regular polysulfone, similar to that of the polysulfone-silane reactive resins. The degree of improvement is usually parallel to the increase in cross-linking density of the cured material. I Because of the dual functionalities present in each polysulfone-vinyl reactive molecule, polymerization usually leads to the formation of a network structure. However, under certain circumstances the polysulfone-vinyl reactive chains can be extended with another comonomer while retaining its thermoplasticity. These thermoplastic resins can be compression-molded to clear or slightly hazy plaques; they are usually brittle and resemble polystyrene. Polysulfone has exceptional chemical resistance, particularly in a strong alkal-ine environment. This quality makes the polysulfone-vinyl reactive resin a.sutiable matrix rein for fabricating corrosion-resistant composite materials. Polysulfone-vinyl reactive resins, while retaining most of th polysulfone's properties, exhibit a number of additional features which are highly desirable for the coating applications. Because of their oligomeric nature, they are characterized by high solubilities in polysulfone-soluble solvents, low melting points and good melt flow characteristics which make them suitable for a variety of fabrication processes, particularly the solution and power coating techniques. The reactive end-groups of the polysulfone-vinyl reactive resins permit curing by either heat, peroxide, U.V., electon beam radiation or other suitable energy sources. Once cured, the coating is transformed to a clear, rigid, tough thermoset possessing excellent solvent, chemical and thermal resistance In contrast to the silane end-capped counterparts, polysulfone-vinyl reactive resins lack inherent bonding capabilities. Better adhesion, however, can be achieved by modifying with say unsaturated silane or silyl peroxide adhesion promoters or suitable polar comonomers. The polysulfone-vinyl reactive resins can be for a variety of coating applications including magnet wire coatings, photocurable coatings and and powder coatings. Due to their reactive end-groups, polysulfone-vinyl reactive resins can be modified to acguire improved properties over the parent polysulfone. This is exemplified by the broad spectrum of polysulfone-vinyl reactive comonomer binder systems shown in Tables VI to X below. The thermoplastic versions of the polysulfone-vinyl reactive resins are useful, for instances, to bring out compatibility between polysulfone and inexpensiv polystyrene. The polysulfone-vinyl reactive resins are also useful as. modifiers for other (reactive) polymers to impart certain desirable polysulfone properties. The resulting compositions can be either copolymers or interpenetrating polymeric networks (IPN's). In addition, the polysulfone-vinyl reactive resins can be used for formulating photocurable printing plates and for making membranes to take advantage of their mechanical rigidity, and chemical resistance; porosity in the membrane can be readily developed by solvent leaching upon curing. The polysulfone-vinyl reactive/comonomer binder system of the invention is often a cross-linked copolymer produced by chain extension with a suitable monomer from the reactive end-groups of the polysulfone-vinyl reactive resin. So the polysulfone-vinyl reactive/comonomer binder systems should be handled like a thermoset. This behavior undoubtedly restrict its melt processability, but it also provides several useful properties being a thermoset. The broad spectrum of comonomers available provide a great deal of freedom to the formulation of such binder systems. Styrene, acrylonitrile and divinyl benzene are among the preferred comonomers for this purpose. Vinylbenzylchloride is the preferred end-capping compound because of its commercial ayailability, attractive economy and good reactivity. A drawback of this reagent is that polysulfone-yinyl reactive resins haying the vinyl benzyloxy end-groups are subject to-thermal-initiated polymerization. This behavior complicates the melt recovery process employed for thestandard polysulfone as well as limits the operating altitude during melt fabrications. This difficulty can be resolvable by the addition of a suitable inhibitor. End-capping of 5,000 molecular weight, hydroxy terminated polysulfone oligomer with vinylbenzyl chloride afforded a thermosetting composition with excellent solvent resistance. At 200 psi, this material did not rupture aftertwenty-five minutes of exposure of acetone, toluene, and trichloroethyl en. Although compression molded plaques were brittle the high cure speed and good flow behavior should make this material 0 interest in coating applications (e.g., powder coating). The properties of the thermosetting polysulfone-vinyl reactive resin and their blends with some epoxy resins are listed in Table A below: The 5,000 MW polysulfone-vinyl reactive resin/epoxy system exhibited excellent flow characteristics, solvent resistance, a high glass transition temperature (Tg) and, good tensile properties.

Capped 10,000 MW PSF The comonomer having at least one monovalent unsaturated organo radical should be one which is not gaseous at ambient conditions. Such comonomer preferably alsp is compatible with the polysulfone-vinyl reactive monomer. The term compatibility, as used herein, means that such comonomer has a reasonable degree of solubility in the polysulfone-viny reactive. For example, styrene is completely soluble in the polysulfone-vinyl reactive monomers, so styrene is very compatible with the polysulfone vinyl reactive monomers. Acrylates have some solubility in the polysulfone-vinyl reactive monomers, so acrylates have some compatibility with the polysulfone-vinyl reactive monomers. Acrylonitriles also have a good degree of compatibility. As used herein, the term "vinyl monomer" broadly means a1 monomer containing at least one of the groups vinyl, vinylidene or vinylene. Vinyl is H2C=CH-; vinylidene is H2C=C=; and vinylene is -CH=CH- Each of such terms includes substituted groups. (Broadly monomers having at least one monovalent reactive unsaturated organo moiety are used as the comonomers.)

Comonomers having three vinyl or allyl reactive moieties, such as triallyl cyanurate, are particularly useful in the crosslinking version of the :invention. such comonomer can be termed crosslinking boosters, as they speed up the crosslinking and give better results, but as they are usually expensive, cheaper difunctional comonomers are used as the main crosslinkers. The vinyl reactive moieties of the end-capped polyarylene polyether and the vinyl reactive moieties of the comonomers c be substituted, but the substituents (e.g., C1) must not be 'directly on either of the double bond carbon atoms of the vin 1 group (i.e., monovalent unsaturated organo group) unless the substituent is alkyl or alkoxy. Commonly used additives can be used in the homopolymerization and copolymerization. Wetting and dispersing agents and thickening agents (e.g., carboxymethyl cellulose) canoe added. Plasticizers (e.g., dibutyl phthalate) can also be added. The amounts added will vary upon the desired results, but preferably each additive is used in the range of about 0. to 10 percent by weight. Polymerization (homo- or co-) can be achieved by the us of free radical initiators, with or without the aid of heat, or by the use of actinic radiation, such as, ultraviolet radiation. Preferably the free radical initiator is a peroxide, and the preferred peroxide is dicumyl peroxide. The polymerization temperature effectively is between 250 (ambient temperature) and 3000C. and preferably is between 1000 and 2500C. The co- or homopolymerization can be effected using slurry suspension or emulsion type oolymerization (with conventional aqueous and non-aqueous solvents and liquid carriers). By way of summary, the invention includes oligomers curable by the free radical mechanism. This is realized by terminating, for example, the polysulfone chains with reactive unsaturated end-groups. The polysulfone-vinyl reactive resin resemble the silane-reactive counterparts in many physical and mechanical properties, but they do not, however, possess adhesive property. The polysulfone-vinyl reactive resins are soluble in styrene, and will copolymerize to give a copolymer (usually thermoset) intermediate in Tg. Such polysulfone-yinyl reactive resin comonomer binder system greatly expands the flexibility in meeting the cost/performance requirements for different potential end-uses. The polysulfonevinyl reactive resins uses include corrosion-resistance maxtrix resins or additives, photocurable coatings, powder coatings, magnet wire coatings, polysulfone modifications and-fiber reinforced structural composites. The data, advantages, methods, etc., concerning the polysulfone-vinyl reactive resins of the invention set out herein is equally applicable to the generic end-capped polyarylene polyether resins of the invention. The following examples are illustrative of the invention.

Polysulfone P-1700 is one of a line of UDEL # polysulfones commercially available from Union Carbide. Polysulfone P-1700 is composed of the recurring units of formula I above (see page 5) with methoxy end-capping moieties. Analytical Methods Determination of Amount of End Capping Agent Needed The amount of end-capping reagent needed, on a 20 percent excess basis, can be calculated from the following equation: End-Capping Reagent (in gm) 1.20 x M x N x V x W HC1 HC1 t 1,000 x W x P x. x wherein M = molecular weight of end-capping reagent, N = normality of HC1/DMSO solution, HC1 VHCl = volume of HCl/DMSO used in ml, W = total weight of reaction mixture in gm, t Ws = sample weight in gm, and P = purity of end-capping reagent. 5 DMSO is dimethyl sulfoxide. This information is needed for determining the amount of reagent required for the end-capping reaction. A titration method is used for this purpose. Upon completion of the polymerization step,a small sample (about 2 to 3 gm) of the reaction mixture is quickly taken from the vessel and placed in a 250 ml Erlenmeyer flask. The sample is weighed and a 50 ml solution of DMSO/MCB (1/1) is introduced (MCB is monochlorobenzene). The sample solution is heated gently on a hot plate until dissolution is complete A drop of bromocresol purple indicator (0.5 percent in methanol) is added and the sample is titrated with a 0.1N HCL solution (in DMSO) to a yellow end point (pH 5.2 to 6.8). Duplicate tests should be made. Test For Completion Of The End Capping Reaction A 1 to 2 gm sample of the reaction mixture is introduce into a 250 ml Erlenmeyer flask containing a 50 ml solution of DMSO/MCB (1/1). The sample solution is heated on a hot plate until dissolution is complete. Two drops of the bromocresol purple solution are added. The reaction is complete if the indicator turns greenish yellow or yellow. Otherwise, the color will be blue indicating the presence of unreacted phenolate end groups. Glass Transition Temperature Determination The glass transition temperature (T ) was measured with g a DuPont 990 instrument fitted with pressure DSC cell at a heating rate of 10-0C. per minute under a nitrogen pressure of 600 psig. (DCS is Differential Scanning Calorimeter; the procedure for using it is described in A. Duswalt, "Industrial Research," July 1975, pp. 42-45.) Comparable values can also be obtained from the temperature-modulus data measured with an Instron machine at a heating rate of 11.5 OC. per minute. Melting Point Determination When heated in a capillary melting point apparatus (e.g., a Thomas-Hoover capillary apparatus), phase transition of a polysulfone-vinyl reactive resin can be visually observes. This test is useful for a rapid but rough identification of a polysulfone-vinyl reactive resin. Mn Determination ì The number average molecular weight (Mn) of the polysulfone-vinyl reactive resins is determined by NMR technique using a Varian 100 MHZ NMR Instrument. Assuming the polysulfone-vinyl reactive resins are completely endcapped, i.e., each molecule is terminated with two unsaturate organo end groups, and there is no hydrolysis of the end groups, they are represented by the following general formula: EMI64.1 wherein n is the number average degree of polymerization. PSF-VR/Comonomer Binder System - Peroxide Curing Compounding -The peroxide, usually DiCup, was dissolved in the liquid comonomer, and-was subsequently mixed with the polysulfone-vinyl reactive resin fluff. When the two components were immiscible, a common solvent of low boiling point, such as acetone, was used to give a homogeneous solution before blending with the resin fluff. The solvent was removed by air drying. The latter method usually provide a more uniform moisture, but some comonomer may be lost due to evaporation. Curing - Unless otherwise specified, all test specimens were cured by compression molding at 1600C. for a ten-minute cycle. These conditions were chosen arbitrarily and may not be optimum for all the binder systems studied. PSF-VR/Comonomer Binder System - Electron Beam Curing Sample Preparation - A 4" x 4n 30 mil plaque was employed for the electron-beam curing. The plaque was prepared by compression molding of a thoroughly blended mixture of the polysulfone-vxnyl reactive resin and comonomer. A mild molding temperature, usually around 1600C.,was used to prevent premature gellation of the formulation. Irradiation - A two-million volt van de Graaf electron accelerator was used as the source of electron beam radiation Different irradiation doses were achieved by varying the exposure time. PSF-VR/Comonomer Binder System - Photocuring Sample Preparation - A formulation, usually containing a polysulfone-vinyl reactive (PSF-VR) resin, a comonomer and a photo-initiator, was thoroughly mixed and was compressionmolded to a 10 mil thick film. By using a molding temperature at or below 1600C., the resulting film remained thermoplastic,' The film was mounted on an 8" x 8" x 5 mil aluminum foil to facilitate handling. U. V. Irradiation - Linde photocuring equipment, having. a flux density of 160 watts/ft2, was used as the U. V. source. Different irradiation doses were accomplished by varying the conveyor speed and the number of passes through the irradiation zones. Gel Content (or Percent Extractables) The gel contents of the cured pollysulfone-vinyl reactive resin samples were measured by solvent extraction in boiling chloroform. The data of percent extractables shown in Tables XVI andAVIII were determined in methylene chloride. The higher the cross-linking is, the greater the gel content and the -lower the percent extractables. Swelling Index Swelling index may be related quantitatively to the cross linking density of a given network structure. The data shown in Table'XVII and XVIII were values measured in methylene 1 chloride and calculated according to the following equation: Weight-of Swollen Sample (Corrected) Swelling Index = ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯ Initial Sample Weight Weight of Soluble Portion Environmental Stress-Crack Resistance Environmental stress-crack resistance data were measured at constant stress levels using an environment of solvent-saturated cotton swab attached to the specimen. Performance was rated on the basis of time elapsed before rupture at a given stress level. Solution Polymerization The desired amounts of polysulfone-vinyl reactive resin and freshly distilled styrene monomer were placed into a pyre glass ampoule. A solution made of freshly distilled monochloro- benzene and benzoyl peroxide (1.67 mg. benzoyl peroxide/l ml monochlorobenzene)was added so that the final solution contained 20 percent of reactants and 0.1 percent of benzoyl t peroxide. The ampoule was degassed at liquid nitrogen temperature and was sealed under a nitrogen atmosphere. Polymerization was carried out at 800C. for a period of 19 hrs. At the end of polymerization, the ampoule was opened and the polymer recovered by coagulation in isopropanol. Reduced Viscosity Determination The reduced viscosity (R.V.) is determined by the procedure of ASTM-D-2857 at a concentration of 0.2 grams of the resin in 100 milliliters of solution. The above information often uses the term polysulfonevinyl reactive resins but is equally applicable to or encompasses the broader term monovalent, unsaturated organo end-capped polyarylene polyether resins. EXAMPLE 1 Allyl Terminated Polysulfone Oligomer To a five-liter four-neck flask was charged 456.56 grams (2.0 mole) of bisphenol A, 1 liter of dimethyl sulfoxide'(DMSO), 2 liters of chlorobenzene and 320.0 g (4.0 mole) of 50 percent sodium hydroxide solution. The resulting mixture was heated to reflux and the water dehydrated using the chlorobenzene/water azeotrope with recycle of the chlorobenzene. After complete dehydration, the chlorobenzene was removed until the pot temperature reached 149 cm. At this point, 553.5 g (1.93 mole) of 4,4'-dichlorodiphenyl sulfone dissolved in 560 grams of chlorobenzene was added and the reaction allowed to proceed at 1370 to 1600C. with removal of the chlorobenzene. Two hours past the addition of the sulfone monomer (the hydroxy terminated polysulfone having been formed) the reaction was cooled to 600C. and 40 grams of allyl chloride added. In 5 minutes, an additional 10.0 grams of 50 percent sodium hydroxide solution was charged and then heated to llO0C. for 1 hour. Oxalic acid (10 g) was added to acidify the reaction, 2 liters of chlorobenzene was added to cut the viscosity and the solution was filtered to remove sodium chloride. The filtrate containing the product was washed seven times with 1.4 liters of water to remove the DMSO and the product was then recovered by processing through a vented extruder at 3000C. to afford 620 grams of pelletized, allyl- ! terminated polysulfone oligomer. EXAMPLE 2 Thermosetting 5,000 Molecular Weight Vinyl End-Capped Polysulfone To a 3-liter round bottom flask was added 300 grams Of the hydroxy terminated polysulfone (Mn = 5,000), 500 ml Of chlorobenzene, and 1000 ml of DMSO. The hydroxy terminate polysulfone was prepared from bisphenol A and 4,4'-dichlorodiphenyl sulfone as described in Example 1. To this solution at room temperature was added dropwise 9.7 gms of 49.6 percent sodium hydroxide (0.12 moles). The reaction mixture darkened significantly on addition of caustic. Then 18.96 g (20 percent excess) 6f vinyl benzyl -chloride (commercially available from Dow Chemical) was added dropwise. The solution was stirred at 300C. for 3 hours and at 7Q0C. for 2 hours. The contents were still basic (pH - 8) after setting overnight at room temperature. Oxalic acid was added until a pH of 3 was obtained. Coagulation of 200 ml of the solution in 1500 ml of methanol, and drying overnight in a vacuum oven (60 mm) at 1200C. yielded a vinyl benzyl end-capped polysulfone (5,000 molecular weight). The sample was compression molded at 2500C./10 minutes. The resulting 25 mil plaque had a tensile modulus of 248,000 psi, tensile strength of 3,040 psi, elongation to break is 1.2 percent, and pendulum impact of 2.4 ft. lb./in. . Environmen tal stress aging tests at 200 psi indicated that the sample swas intact in acetone, toluene and trichloroethylene for over 25 minutes. The material, however, swelled in trichloroethylene. EXAMPLE 3 Thermosetting 10,000 Molecular Weight Vinyl Benzyl End-Capped Polysulfone A A vinyl benzyl end-capped polysulfone (10,000 molecular weight) was prepared as in-Example 2 above, except that in this preparation a hydroxy terminated polysulfone olisomer (10,000 molecular weight) was employed. The hydroxy terminated polysulfone oligomer was prepared from bisphenol A and 4,4'-dichlorodiFhenyl sulfone as described in Example 1. The vinyl end-capped polymer was compression molded at 250 C. for 10 minutes. A 15 mil plaque exhibited a tensile modulus of 320,000 psi, a tensile strength of 11,000 psi, an elongation to break of 6 percent and a pendulum impact of 27 ft. lb./in.3. At 200 psi, it took 480 sec. for failure of the sample in trichloroethylene. In acetone and toluene, the failure was instantaneous. A significant resistance to trichloroethylene is useful in some electrical applications. EXAMPLE 4 Coating Systems Based on Allyl Terminated Polysulfone Allylic terminated polysulfone prepared as in Example 1 above was dissolved in methylene chloride solvent to provide 10 percent solids-containing solution. Several steel wD 1 plates, 10 mils thick, were dip coated in this solution and dried at room temperature for 10 minutes which was followed first by oven drying at 1250C. for 45 minutes and then by various high temperature oven time bake exposures at 3150 to 3200 C. Upon weighing the residual coating baked onto the steel, the coatings were subjected to CH2C12 extraction by immersion in the stirred solvent bath. The appropriate graph in Figure 1 illustrates that the degree of solubility to methylene chloride is an inverse function of bake time exposure in an oven at 315 to 3209C. Similar extraction data following the identical procedure outlined above was obtained for glass and chrome substrates coated allylic terminated polysulfone (prepared as in Example 1 above) and for controls which had P-1700 polysulfone coatings. The appropriate graph in Figure 1 - illustrates the methylene chloride solubility curve for the glass-plated substrates; and the graph in Figure 2 illustrates the methylene chloride solubility curve for the chrome-plated substrates. Steel "D" plates coated with either P-1700 polysulfone coatings or the allyl-terminated polysulfone (prepared as in Example 1) were subjected to acetone and methylene chloride extraction by immersion. The data and results are set out below in Table II: TABLE II SOLVENT POLYSULFONE AND SUBSTRATE -TYPE TREATMENT RESULTS Steel "D" P-1700 Acetone, Stress cracked Plate 1 minute coating. immersion.

P-1700 Acetone, Coating dissolved. 10 minute immersion. Allyl Acetone, No effect. Terminated 10 minute immersion. The data of Table II shows that acetone and methylene chloride immersion caused stress cracking or dissolution of the P-1700 - polysulfone coatings, but did not have any effect on the allylterminated polysulfone coatings of this invention. Several samples of aluminum sheet (7.5 mils thick, type 3003 H 14) were also coated as described in the procedure above and baked. The coated aluminum plates were subjected to acetone and methylene chloride extraction by immersion, in some cases followed by dipping in hot sodium hydroxide solution. A comparison of the solvent resistance (data and results) of allyl terminated polysulfone and conventional P-1700 polysulfone is set out below in Table Ill: TABLE III SOLVENT POLYSULFONE AND SUBSTRATE1 TYPE TREATMENT RESULTS luminum P-1700 1 minute in Aluminum attacked.

Note: All substrates were given at least one 900 bend in the test coupon prior to solvent resistance testing. The data of Table III shows that acetone and methylene chloride immersion caused stress cracking or coating removal of the P-1700 polysulfone coatings, but did not have any effect on the allyl-terminated polysulfone coatings of this invention. Dipping in hot sodium hydroxide solution, after the solvent immersion step, had no effect with the allyl-terminated polysulfone coatings but did attach the aluminum substrates associated with the P-1700 polysulfone coatings. Both the allylic-terminated polysulfone and P-1700 polysulfone coatings released from glass substrates after baking when exposed to hot detergent solutions (800C. - 14 minutes). On one case, the control P-1700 did not show chlorinated solvent resistance whereas the allyl terminated and baked coating provides solvent resistance (chlorinated and acetone) yet may be readily removed with hot detergent solutions. EXAMPLE 5 Into a four-necked, two-liter cotton Flask, equipped with a mechanical stifre, water trap, condenser, thermometer, addition funnel, and argon inlet, there was placed 183.16 gm of bisphenol A (0.8 mole), 550 ml of DMSO and 700 ml of monochlorobenzene (MCB). The slurry was heated to about 80 Cq to give a clear solution. An aqueous solution of 64.96 gm of sodium hydroxide (98.5 percent purity, 1.6 mole) in 75 ml of distilled water was introduced. Azeotropic distillation began at 1190C. and was continued until the temperature reached 155C. in 4 hrs. During this period a total of 792.2 gm of distillate was collected, which contained 135 ml of aqueous layer. The reaction vessel was cooled to 1400C. and a hot solution of 208.86 gm (0.728 mole) of 4,4'-dichlorodiphenylsulfone (sulfone monomer) in 250 ml of monochlorobenzene was introduced rapidly into the reaction vessel. Distillation of( monochlorobenzene resumed until the reaction temperature attained 1650C. when an additional 319 gm of monochlorobenzenf was distilled off. The polymerization was maintained at this temperature for an additional 90 minutes. Material balance at this point is shown as follows: Reactor Charge- Water-trap Material gm Discharge, gm Bisphenol A 183.16 Sulfone monomer 208.86 NaOH solution 139.96 (mLnly MKE;+ water) DMSO 589.60 MCB 1,050.70 Total 2,172.28 1,111.20 There was 1,061.08 gm of reaction mixture remaining in the ,vessel and the polysulfone oligomer concentration was about 38 percent. Samples were drawn from the reaction vessel for sodium phenolate end-group analysis. The amount of vinyl benzyl chloride required on a 22 percent excess basis was found to be 30.8 gm (0.198 mole). The reaction mixture was brought to a temperature of 1150C., and a solution of vinyl benzyl chloride(the end-capping reagent) in 30 ml dry monochlorobenzene was introduced. The: reaction was kept at this temperature for 90 min. until the bromocresol purple test became yellowish in color. Thereafter, the reaction was stopped, and the reaction mixture was cooled down to room temperature. The hazy, viscous solution was diluted with 600 ml of monochlorobenzene and was filtered to remove the salt. The clear, amber-colored filtrate was poured into a Waring blender containing a large excess amount of isopropanol (or methanol) to coagulate the polysulfone-vinyl reactive PSF-VR resin which was washed twice more with isopropanol, filtered and was dried under vacuum at 750C to yield a white, powdery solid.

(d) The hydroxy terminated polysulfones which were vinyl end-capped were prepared from bisphenol A and 4,4'-dichlorodiphenyl sulfone as described in Example 1. The 0.22 RV, 2-chloroethyl methacrylate end-capped polysulfone-vinyl reactive resin shown in Table IV is an example of low end-capping efficiency. Its deficiency is reflected by the higher than expected number average molecular weight (M ) value calculated on the assumption of 100 percent, n end-capping efficiency. Such a resin may contain up to 30 percent of non-curable fraction as evidenced by solvent extraction test. When the above mentioned precautions are observed during the preparation, however, this difficulty may be largely alleviated. It has been found that, analogously to the behavior of1 polysulfone-silane reactive resins, glass transition temperature (Tg) of a polysulfone-vinyl reactive resin increases with increasing molecular weight and, eventually, approaches that of the standard polysulfone. Figure 4 shows the above relationship for a series of vinyl benzyloxy endcapped polysulfone-vinyl reactive resins. (The hydroxy terminated polysulfones which were vinyl end-capped were prepared from bisphenol A and 4,4'-dichlorodiphenyl sulfone as described in Example 1.) The hollow circles indicate the Tg values of the virgin samples. In each instance the virgin sample was heated to a temperature of 2170C., cooled, and then measured again to study the effect of thermal history. The second reading was often found to be several degrees higher, which is a sign of resin advancement. Above the Tg, there is a rubbery polymer; below the Tg, there is a glassy polymer EXAMPLE 10 Polysulfone-vinyl reactive resins containing (a) vinyl ether ethoxy end-groups, (b) methacryloxy ethoxy endgroups and (c) vinyl benzyloxy end-groups were subjected to thermal abuse at several temperatures.

EXAMPLE 13 Some of the thermal and mechanical properties of more polysulfone-vinyl reactive resin/comonomer compositions, but with comonomers containing multiple unsaturation, are set out in Table ylllbelow. (The hydroxy terminated polysulfones which were vinyl end-capped were prepared from bisphenol A and 4,4'-dichlorodiphenyl sulfone as described in Example 1.) These comonomers, in theory, should result in network structures of much higher crosslinking densities. Even though the polysulfone-vinyl reactive resin exhibited only limited solubility at room temperature in many of the comonomers studied, in most instances the molded plaque possessed a good clarity and a single glass transition tnperature characteristic of a copolymer Because of questionable compositional uniformity achieved in the preparation of these blends, the true loading of a comonomer in a test specimen may vary significantly from the value indicated. This is thought to be reflected by some erratic glass transitional temperature values. Roughly speaking, however, the glass transitional temperature of the cured compositions varied according to those of homopolymers derived from the corresponding comonomers as well as- the comonomer loadings. Because of their thermoset nature, the cured resins ;exhibited a markediy improved environmental stress-crack resistance and a better dimensional stability at elevated temperatures than those of the thermoplastic polysulfone.

K EXAMPLE 14 By employing polysulfone-vinyl reactive resins of various initial molecular weights, polysulfone-vinyl reactive comonomer binder systems having different cross-linking densities as well as polysulfone block lengths can be prepared. The effect on the properties three compositions which are otherwise identical except for the above-mentioned aspects, are set out in Table IX below. (The hydroxy terminated polysulfones which were vinyl end-capped were prepared from bisphenol A and 4,4'-dichlorodiphenyl sulfone as described in Example 1.) The mechanical properties of the cured materials' are similar. The environmental stress-crack resistance and residual moduli at 2O00C., however, improves with decreasing initial molecular weights of the polysulfone-vinyl reactive resins; which is consistent with the anticipated direction of increasing cross-linking densities. Since the polysulfonevinyl reactive and the styrene monomer are miscible in allproportions, such a binder system can be a free-flowing powder, a dough, a paste or a solution depending on the relative amount of styrene incorporated. Preliminary data showed that in all instances a copolymer composition was obtained. The glass transitional temperature of the latter went down with increasing - amount of polystyrene blocks in the cured resin. The glass transitional temperature values of copolymers at 10, 17.4 and 30 percent polystyrene levels (calculated on the basis of styrene monomer used initially) were found to be 1450, 1400, and 1300C., respectively.' Addition of divinyl benzene resulted in a higher Tg with no apparent deleterious effect on the-iaechanical properties as shown in Table IX below.

(The hydroxy terminated polysulfones which were yinyl end-capped were prepared from bisphenol A and 4,4'-dichlorodiphenyl sulfone as described in Example 1.) Properties of some irradiated materials are summarized in Tables X and XI below. Standard polysulfone (Union Carbide Corp., P-1700) was found to undergo no apparent cross-linking with or without the comonomer additive, under the same conditions. MRAD is a radiation unit or Meg Rad; Rad is 100 ergs per gram.

Comonomers, Neopentyl glycol diacrylate (30 percent); Styrene (10 percent). (b) Corrected for extractables. Within the radiation dosage of 5 to 20 Mrad, there was found no significant difference in cross-linking densities of the irradiated samples. This is supported by experimental data shown in Table XI above, where the cross-linking density is expressed in terms of swelling index and residual modulus at 3000C. The polysulfone-vinyl reactive bearing the end reaction groups is necessary for cross-linking. Polysulfone alone or with comonomer will not crosslink without the vinyl reactive end groups. The rather low degrees of cross-linking (up to 70 percent gel content) of the above irradiated samples is believed to be due to at least partially, an incomplete end-capping of the polysulfone-vinyl reactive resins used. Spectroscopic data showed the soluble fraction being entirely polysulfone; no polystyrene was detected. EXAMPLE -16 When a photosensitizer is added, the polysulfone-vinyl reactive/comonomer binder system becomes photo-curable; even though polysulfone is known to be an U. V. absorbent. A polysulfone-vinyl reactive film containing benzophenone and ethyl acrylate was irradiated with Linde U. V. curing equipment for different intervals, and the results are summarized in Table XII below. (The hydroxy terminated polysulfones which were vinyl end-capped were prepared from bisphenol A and 4,4'-dichlorodiphenyl sulfone as described in Example 1.)

(80%); ethyl acrylate (19percent); benzophenone (1percent). U.V. catalyst necessary when cured by U.V. (b) Expressed in number of passes at a conveyor speed of 100 ft/min. Because of the film thickness (about 10 mil) the degree of cross-linking achieved was relatively low even after twelve passes. The partially cured sample, however, was flexible, tough, and showed a significant improvement in environmental stress crack resistance. Thus the use of a comonomer in conjunction with the polysulfone-vinyl reactive offers a 3number of advantages: (1) to render the formulation curable by conventional methods; (2) to permit property modifications through a wide selection of comonomers; and (3) to allow flexibility in meeting the cost/performance requirements for different end-use areas. EXAMPLE 17 Upon cross-linking, polysulfone-vinyl reactive resins 3exhibit a marked improvement in environmental stress-crack resistance over the regular polysulfone, similar to that of the polysulfone-silane reactive resins. The degree of improvement is usually parallel to the increase in cross5linking density of the cured material. This effect is demonstrated clearly by the data shown in Table XIII below where the environmental stress crack resistance of a series of cured polysulfone-vinyl reactive styrene resins are relate to their swelling indices. The cross-linking density is expected to increase with a decrease in the initial molecular weight of the polysulfone-vinyl reactive, which is reflected by a lowering in the swelling index. The environmental stresscrack resistance data was measured at constant stress levels using an environment of solvent-saturated cotton swab attached to the specimen.

EXAMPLE 18 The environmental stress-crack reistance of a cured polysulfone-vinyl reactive comonomer composition also depende on the type and loading of comonomer employed. (The hydroxy terminated polysulfones which were vinyl end-capped were prepared from bisphenol A and 4,4'-dichlorodiphenyl.sulfone as described in Example 1.) Table XIV below sets out the environmental stress-crack resistance performance, in decreasing order, of 20 different types of matrices in toluen and trichloroethylene. Three of the more effective comonomer among those studied were divinyl benzene, acrylonitrile and styrene. The neat polysulfone-vinyl reactive resin also performed well upon cross-linking and is comparable to crosslinked polysulfone-silane reactive resin.

V.) with styrene in mono-chlorobenzene was carried out to partial competition to minimize the tendency of premature crosslinking. Nevertheless, when the weight percent of PSF-VR in the feed exceeded 30 percent, complete gelation usually resulted. Between 12.5 and 30 percent polysulfone-vinyl reactive loadings in the feed provided partially gelled products. Soluble copolymers were also prepared at poly suifone-vinyl reactive charges below 12.5 percent. The characteristics of some of the soluble copolymers are shown in Table XV below. Compositions of these copolymers were determined by elemental analysis. In every instance the polysulfone-vinyl reactive was found to be richer in the copolymer than in the feed. They are soluble in methyl ethyl ketone or toluene, which are non-solvents for the polysulfonevinyl reactive homopolymers. The molecular weights of the products increased rapidly with inreasing polysulfone-vinyl reactive/styrene charge ratios. These thermoplastic resins can be compression-molded to clear or slightly hazy plaques; they are usually brittle and resemble polystyrene. Any advantage of raising the glass transition twerature of polystyrene by copolymerizing withpolysulfone-vinyl reactive was found to be minor. Preliminary DSC data showed that the glass transition temperature of the copolymers increased only slightly from that of polystyrene (Tg 1000C) at these levels of polysulfone-vinyl reactive contents; substantial increases were achieved only at high loadings of polysulfone-vinyl reactive component. 1 TABLE XV (a) SOLUTION COPOLYMERIZATION OF PSF-VR WITH STYRENE (a) PSF-VR/styrene 0/100 5/95 7.5/ 10/90 12.5 Wt. ratio in feed 92.5 87.5 (a) (b) PSF-VR/polystyrene 0/10 9.27/ 16.4/ 14.9/ 24.7/ Wt. ratio in copolymer 90.73 83.6 85.1 75.3 (c) R.V., dl/gm 0.51 0.58 0.61 0.70 1.06 Conversion, percent 48 49 48 55 50 Notes: (a) Polysulfone-vinyl reactive, acryloxy ethoxy end-groups, 0.23 R.V.

(The hydroxy terminated polysulfones which were yinyl end-capped were prepared from bisphenol A and 4,4'-dichlo- rodiphenyl sulfone as described in Example 1.) The mechanical properties of two of the glass mat reinforced polysulfone-vinyl reactive laminates were compared to those of a laminate formulated with a commercial corrosion-resistant polyester resin (ICI Atlac 382-05B) - the results are given in Table XVI below. In addition to their good mechanical strength, the finished laminates also exhibited a high gloss and smooth surface comparable to the commercial material. A very high heat deflection temperature was obtained with the laminate made from the vinyl benzyloxy end-capped, 0.17 R. V. polysulfone-vinyl reactive resin (which may be the result of a higher cross-linking density attained with this particular resin). The electrical properties of one of the glass mat reinforced polysulfone-vinyl reactive laminate are listed in Table XVII below together with those of a laminate made with a commercial polyester resin (Freeman Stypol-2995). Performance of both matrix resins are rated excellent.

(The hydroxy terminated polysulfone was prepared from bisphenol A and 4,4'-dichlorodiphenyl sulfone as described in Example 1.) The mixture was heated to 900C. to give a homogeneous solution. Thereafter, 1 ml of a NaOH solution (28.8 percent, equivalent to 0.0072 mole) was introduced together with 25 ml of benzene. Azeotropic distillation began at about 1150C. and was allowed to continue until no more water was forming. A total of 2 ml water was collected. The reaction vessel temperature was raised to 1350C. and a solution of 3.8 g of allyl chloride (0.05 mole) in 5 ml of dimethyl sulfoxide was added. The reaction medium turned to a light amber color and the solution was kept at a temperature between 125e to 1300C for a period of 45 minutes. Upon cooling to room temperature, the salt was removed by filtration. The filtrate was poured into a, large excess of isopropanol and a white fluffy solid was recovered. The conversion was better than 98 percent (19.7 g). It showed a reduced viscosity of 0.18 dl/g in chloroform at 250C. Infrared spectrum of a film cast from CHCl3 indicated that the resulting sulfone oligomers no longer possessed hydroxy end-groups. The product was an alloxy (allyloxy) end-capped polysulfone-vinyl reactive resin (oligomer). EXAMPLE 24 Using the same apparatus as described in Example 23 but employing the following starting materials and reagents. Hydroxy terminated polysulfone 39 gm (D.001 mole) (molecular wt. 39,000) KOH (in the form of a 11.28 0.112 gm (0.002 mole solution) Dimethyl Sulfoxide 200 ml Benzene 80 ml Allyl Chloride . 1.147 gm (0.015 mole) (The hydroxy terminated polysulfone was- prepared fran bisphenol A and 4,4'-dichlorodiphenyl sulfone as described in Example 1.) The end-capping reaction and- product isolation were carried out following the procedures used in Example 23. 38 g of a white fluffy polysulfone-vinyl reactive polymer was recovered. It showed a reduced viscosity of 0.58 dl/gm inchlorofonnat250c. EXAMPLE 25 Ten grams of the alloxy end-capped polysulfone resin prepared in Example 23 was placed between two sheets of aluminum foil and the assembly was pressed at 2400 C. for a period of 15 minutes. T-peel test showed the peel strength between the aluminum foil and polysulfone to be between 4 to 8 lbs./in. EXAMPLE 26 A solution of 0.1 gm of each of 2,5-dimethyl-2,5-bis- (trimethylsilylperoxy)-hexane and triallylcyanaurate in hexane was intimately blended with 5 gm of the alloxy end-capped sulfone oligomer prepared in Example 23. Upon being intimately blended, the hexane was removed under vacuum at 5,00C. The dried blend was molded with an electrically-heated hydraulic press at 2400C. for a 15 minute cycle. The resulting plaque was partially soluble in chlo,roform, and the presence of cross-li,nked gels was visible. EXAMPLE 27 An alum'inum polysulfone-aluminum joint was prepared with the alloxy terminated polysulfone resin prepared in Example 23 an,d aluminum O-panels. The polysulfone-vinyl reactive resin adhesive layer was cured by adding 2 percent of each of 2,5-dimethyl-2,5-bis- (trimethyl-silylperoxy) hexane and triallylcyanurate in a manner as described in Example 26. The finished joint was measured for T-peel strength with an Instron machine'at a cross-head speed of 2 inches per minute. The-ralue was S to 6 lbs./in. Under similar conditions, joints made of standard polysulfone showed less than 2 lbs./in. peel strength. EXAMPLE 28 Alloxy terminated polysulfone resin prepared from Example 23 was molded at 2100C. to a 25 mil thick plaque. A set of lap-shear joints was subsequently made with the above plaque and titanium bars (1" x 4" x 55 mil). A peroxide initiator, vinyl tris-(t-butylperoxy) silane, was used to prime the surface of both the polysulfone-vinyl reactive resin layer and the titanium substrates. Curing was effected at 2300C. for a ten minute cycle. Lap-shear strength of the above joints was measured to be 880 psi.

Air was displaced by N2 and 16.03 grams of 49.90 percent NaOH (0.2 mole) was added. The mixture was refluxed, removing water until no more was evident, and then toluene was-distilled off to a pot temperature of 1600C. A solution of 24.15 grams of 4,4'-difluorodiphenyl sulfone (0.095 mole) and 33 milliliters of dry chlorobenzene were added.
