Abstract: The quaternary ammonium monomers of this invention have the formula wherein R is an ethylenically unsaturated organic group R¹ is a linear C₁ to C₄ alkyl group, optionally hydroxy substituted X is chlorine, bromine or iodine, and Y ⊖ is a surfactant anion. The epoxides derivable from the halohydrin of Formula (I) are other monomers of this invention. The monomers are soluble in common organic solvents and comonomers. The invention is also directed to addition po­ lymers of these monomers and to methods or producing both the monomers and the colymers. The halohydrin monomers and the polymers are stable at acid pH values although capable of reacting with materials reactive with the hydroxyl and/or ha­ lide groups. Upon heating, they are self-reactive and can be­ come cross-linked. At alkaline pH values they become self-­ reactive; the polymers crosslink slowly even at room tempera­ ture, with a crosslinking rate increasing rapidly with tempera­ ture. The monomers are particularly efficiently incorporated in­ to copolymers. Polymers containing the novel monomers are useful as coating, binding or impregnating compositions.

Description: QUATERNARY AMMONIUM COMPOUNDS CONTAINING SURFACTANT ANIONS, POLYMERS ThEREOF, POLYMERISABLE COMPOSITIONS CONTAINING THEM, METHODS OF MAKING THE MONOMERS AND POLYMERS AND ARTICLES CONTAINING POLYMER This invention is concerned with quaternary ammonium compounds containing surfactant anions, polymers thereof, polymerisable compositions containing them, methods of making the monomers and polymers and articles containing polymer. Polymers according to the invention are useful, inter alia, in coating, binding and impregnating compositions. U.S. Patent Nos. 3,678,098 and 3,702,799 discuss the state of the art of reacting epihalohydrins with a number of different organic compounds to provide a great variety of products. These patents relate more particularly to the production of unsaturated acid ester monomers, including acrylic or methacrylic acid esters, to produce useful quaternary ammonium salt monomers capable of reacting with monomers containing vinyl unsaturation by addition polymerization. Filed on the same date as this application is European Patent application no. , which claims priority from U.S. serial No. 291,143 directed, inter alia, to monoethylenically unsaturated quaternary ammonium salt monomers(which may be readily polymerizable with vinyl acetate) and to the polymers produced therefrom. Also filed on the same date as this application is European Patent application No. , which claims priority from U.S. serial No. 291,142 directed, inter alia,to monoethylenically unsaturated quaternary ammonium salt monomers containing aromatic components and to the polymers of such monomers. The above identified patents and applications relate to monomers which comprise a halohydroxypropyl quaternary ammonium group, as does the present application. While the above identified patents and applications provide useful compounds, the monomers are generally water soluble salts which are insoluble in many organic solvents and potential comonomers. These monomers may have strong base cations, and in their polymers and copolymers this strongly cationic behaviour may persist In contrast, monomers according to the present invention are generally soluble inorganic solvents, can have a less pervasive ionic character and this lesser degree of ionic character may persist in the polymers of these monomers. Thus, the polymers of the present monomers may be compounded with anionic materials, such as pigments and thickeners, without encountering severe coagulation or stability problems. These objects may be achieved while maintaining, in the polymer, desirable low energy cure characteristics, i.e. curability, preferably at ambient or somewhat higher temperatures such as 200C to 1000C, AccordirU to one aspect of this invention there are provided quaternary ammonium monomers having the formula EMI2.1 wherein R is an ethylenically unsaturated organic group R1 is a linear C1 to C4 alkyl, optionally hydroxy substituted X is chlorine, bromine, iodine or a functional equivalent of a halogen, and is a surfactant anion. As the above compounds are salts of quaternary ammonium ions and lipophilic anions, they are quaternary liposalts. In a first preferred embodiment (a) the ethylenically unsaturated organic group R is: CH2=C(R4)-C(O)Z-A wherein R4 is hydrogen or methyl, Z is oxygen or -NR5where in R5 is hydrogen or hydrocarbyl having up to about 10 carbons, preferably hydrogen or methyl, and A is a (C2-C4) alkylene group having at least two carbon atoms in a chain between the adjoined Z and N+ or A may be a polyoxyalkylene group of the formula - (CH2CH2o) XCH2CH2 wherein x is an integer, preferably from 1 to 11. In a second preferred embodiment (b); R is the structure R3 - CH2-(CHR2) )n-CH2- (Il) wherein n is 0 or 1 R2 is H or OH, and R3 is an alkenoxy group containing an allyl group or a carbalkenoxy group containing a double bond functionally equivalent to an isolated vinyl group. In a third preferred embodiment (c); R is the structure EMI5.1 wherein y is an integer from 1 to 4. Throughout this disclosure this structure III will also be referred to as an "arvinylphenylenylalkylenyl" group A detailed description of the cation portion of those monomers of the first embodiment (a) wherein Z is oxygen is given in United States Patents 3,678,098 and 3,702,799. In the present invention Ye is a surfactant anion. In the resulting monomer the ethylenically unsaturated group is linked to the rest of the molecule by means of an ester linkage and A is preferably ethylenyl. When Z is -NR5- the linkage is by means of an amide group and A is preferably ethylenyl or propylenyl. In this first embodiment, (a), preferred R groups are I , ethylenically unsaturated monovalent groups such as substituted C1-C4 alkyl acrylates or methacrylates and the corresponding substituted N-alkyl acrylamide and methacrylamides; The monomers of preferred embodiment (a) can be homopolymerized, copolymerized with each other and copolymerized with other ethylenically unsaturated monomers as taught in U.S Patent 3,678,098 column 2, line 75 through column 3, line 66. The second preferred embodiment (b) includes monomers having a surfactant anion and a quaternary ammonium cation described in the European Patent Application corresponding to U.S. Patent application serial No. 291,143. Preferred embodiment (c) includes quaternary ammonium monomers having a surfactant anion and a quaternary ammonium cation described in the European Patent Application corresponding to U.S. patent application serial no. 291,142. For each of the monomers (I), it-is preferred to copolymerize them with monomers having similar relative reactivity ratios as taught by C. Walling in Free Radicals in Solution, John Wiley, 1957, Chapter 4 and Bandrup and Immerget et al, Polymer Handbook, John Wiley, 1975, Section II, n.b. pages 249-257. Among useful comonomers are: acrylate esters, preferably of C1-C8 alcohols, methacrylate esters, preferably of C1-C8 alcohols, acrylic acid, methacrylic acid, itaconic acid, styrene, alkyl styrenes, vinyl esters, preferably of C1-C12 acids especially vinyl acetate, acrylamide, methacrylamide, acrylonitrile, maleic anhydride, vinylidene chloride, N- vinylpyrrolidone, maleate esters, preferably of C1-C8 alcohols, fumarate esters, preferably of C1-C8 alcohols, propylene, ethylene and other olefins, vinyl chloride and vinyl toluene. In a preferred process of the present invention, a hydrogen acid salt of the tertiary amine, RN(R1)CH3 is reacted under suitable conditions with an epihalohydrin, i.e., EMI7.1 in which X is chlorine, bromine, iodine or a group functionally equivalent to a halide, to form a halohydroxypropyl dialkyl quaternary ammonium compound. Exchange of the acid salt anion for a surfactant anion then yields the compound of Formula (I). Preferably, the hydrogen acid employed to form the salt of the tertiary amine is a simple inorganic acid such as a halogen acid, a phosphoric acid, a sulfuric acid, including the acids of low molecular weight organic sulfates, such as methyl sulfate, carboxylic acids and so forth, with the acids having a ionization constant, pKa, of 5.0 or less; most preferred are hydrochloric and, especially so nitric acids. An alternative process uses a hydrogen acid of a surfactant anion to form the salt of the tertiary amine. The tertiary amine surfactant salt is then reacted under suitable conditions with an epihalohydrin to form the compound of formula (I) The latter alternative can be carried out in an organic solvent our a mixed water-solvent system, particularly employing a monomer as the solvent which monomer is to be a comonomer for a subsequent copolymerization with the formula (I) compound. above aescrluea In brief summary, the process/for producing the --- - - - - monomer may oe /- as tne conversion or a tertiary amine to a hydrogen acid salt followed by reaction of the hydrogen acid salt at a pH between about 6 and about 8 with an epihalohydrin, followed by anion exchange as described hereinbelow and further acidification and dilution to the level of concentration desired for ultimate use of the monomer solution. It should be noted that once the hydrogen acid salt of the tertiary amine is formed, the reaction with the epihalohydrin can be conducted by any of the methods described in the aforementioned U. S. patent 3,678,098, particularly the examples and the section beginning at line 68 of column 1 anu concluding at line 17 of column 2, In a further embodiment the halo hydroxy propyl dialkyl quaternary ammonium compound of formula- (.T) is converted to the corresponding epoxide of formula (IV), by raising the pH by introducing an alkaline material. By the introduction of an equivalent or more of alkaline material the monomer of formula (I) may be completely converted to that of formula (IV) although it may sometimes be desirable to have the mixture of monomers obtained by the incomplete conversion. The alkaline materials are inorganic alkalis such as the alkaline and alkaline earth caustics, sodium hydroxide, potassium hydroxide, calcium hydroxide, the corresponding carbonates and other alkaline salts of the alkaline earth metals. It is preferred that all of the reaction steps up to the exchange of the small ion for the surfactant anion be carried out in an aqueous medium, usually comprising a water-miscible organic solvent, because the rates of reaction may be most favorable in such medium. Monomers of formula (IV) are particularly useful in both emulsion and solution polymerization processes to make both copolymers and homopolymers. The comonomers employed are those which are not reactive with the epoxide group, so the products are vinyl addition copolymers. In the solution polymerizations solvents are chosen which are not reactive with the epoxide group; aromatic hydrocarbons and mixtures of these with other non-reactive solvents are preferred. Polymers of the monomers of formula (IV) are normally used without further activation steps. To increase the speed of the crosslinking reaction the copolymers of the monomers of formula (I) are activated by raising the pH to neutral or alkaline conditions, from the acid conditions under which they are normally maintained because of their greater stability with respect to gelation. In general aqueous systems comprising polymers of the monomers of formula (I) are maintained at pE values below 6 and are activated by raising the pH above 6 by the addition of alkali; the more alkali, and the higher the pH resulting, the more rapid is the curing of the polymer. It is thought that the mer units derivable from the monomers of formula (I) become converted to those of formula (IV) under alkali conditions and that alkali catalyzed transformations of the glycidyl groups can cause cure and insolubilization of the polymer. Polymers of the present invention containing mer units corresponding to formula (I) to a pH may be raised/aboMe 7, such as to the 9 to 12 region with out fear of rapid gelation. The polymer so obtained is stable for a limited amount of time even though such a polymer may not be stored indefinitely without loss of functionality. Polymers of the monomers of formula (I) when activated by a caustic treatment for a period of about 1 to about 5 hours can be reactive and readily crosslinked particularly when used as coatings, binders or adhesives; at high pH values shorter times, such as a few minutes, may be used. Thus by using polymers which represent mixtures of mer units derived from the monomers of formula (I) and those of formula (IV) and by control of pH a manufacturer may achieve balances of stability1 ease of activation and reactivity or curing level not realizable in the prior art. The glycidyl quaternary ammonium liposalt monomers of formula (IV) can be prepared from the monomers of Formula (I) by either of two methods. In one method the nitrate salt, or other small anion salt, of the halohydrin quaternary is treated with a mild base, such as potassium carbonate, in a waterorganic solvent mixture and converted to the epoxide. The epoxide is then converted to a liposalt. In the second procedure the halohydrin quaternary salt of the small anion is first converted to a liposalt in solution in an organic solvent and then a mixture of the liposalt solution and water is treated with a base, such as sodium hydroxide or potassium carbonate, to convert the - dissolved halohydrin to the epoxide. The epoxide will by in the organic solvent and this solution may then be washed with water to remove the traces of the small anion salt formed. The glycidyl liposalt monomers of Formula (IV) are readily polymerized in bulk, solution emulsion or suspension polymerization processes, solution and emulsion being preferred. Care must be taken not to include among the comonomers materials which are well known in the art to be reactive with the epoxide group under the conditions chosen for the polymerization. In both polymers and monomers the glycidyl group and the halohydrin group may be interconverted by treatment with appropriate acidic and alkaline materials. Acids, such as hydrochloric acid, when added to a system comprising the glycidyl group will convert it to the halohydrin. Alkaline materials when added to a system comprising-the halohydrin group convert it to the glycidyl group. The epihalohydrin used for the purposes of this invention may be the epiiodohydrin or the epibromohydrin. It is Dreferable, however, to use the epichlorohydrin. It has been found that there might be a relationship between the rate of round that tnere /- relatlonsnlp Between tne rate or reaction (of the epihalohydrin with the amine hydrogen acid salt) and the nature of the R1 substituents on the amino nitrogen. For that reason, it will generally be preferred that Rlis methyl. Neverthe less, strict adherence to the selection of R1 as described above may provide acceptable reaction rates of the amino salts with any of the epihalohydrins. As will be seen from the Examples, the monomers of the present invention are suitablv prepared and stored as solution. This is not a critical limitation, and if desired, they may be concentrated and/or isolated from the reaction medium-in which they are dissolved by removal of th. solvent, typically by vaporization under vacuum, or by crystallization. Preferred embodiment (3) of the present invention provides a group of ethylenically unsaturated monomers of the quaternary ammonium type which are especially useful in copolymerization with vinyl acetate type monomers to provide copolymers capable of low energy curing. Thus, this embodiment may permit-the development of monomers and polymers similar to those disclosed in the above U.S. patents, but with properties to meet specific application requirements particularly when copolymerization with a vinyl ester is desired. In preferred embodiment (B) X is as defined previously, n is 0 or 1, Y - is a surfactant anion, R1 is (C1-C4) straight chain alkyl optionally hydroxysubstitutedr R2 is H or OH, and R3 is an alkenoxy group containing an allyl group or a carbalkenoxy group containing a double bond functionally equivalent to an isolated vinyl group. The term isolated is used herein to distinguish the double bond from conjugated or cumulated double bonds. Thus, for example, acrylates and methacrylates contain vinyl groups which are conjugated with the carbonyl group whereas 3-butenoates contain isolated vinyl groups. It is also recognized, however, that it is not essential to have terminal isolated double bonds; accordingly the term "functionally equivalent" is intended to encompass the 2-substituted 5-norbornene compounds. Similarly, it is recognized that the doubly conjugated double bonds also act functionally equivalently to the isolated vinyl groups; a total structure of this type would consist of a vinylene group enclosed between two carbonyls. The ultimate requirement is that such groups not interfere with the general characteristics of the quaternary compounds particularly their ability to form addition copolymers and the ability of such copolymers to crosslink for the Purposes described further embodiment subsequently nerein. H/prererrea/ or tne invention is wneein one / n in the above formula is 1, R1 is methyl, R2 is -OH t . R3 is allyloxy, X is chloro and Y-is a surfactant anion. Preferred embodiment (C) of the present invention provides a group of phenylene-containing monomers of the quaternary ammonium type which can be usefully employed the production of polymers having the desirable characteristics associated with phenylene groups without diminution of the characteristics associated with the low energy curability and quaternary ammonium functionality. In this way, the usefulness of the monomers and polymers disclosed in U.S. Patent Nos. 3,678,098 and 3,702,799 can be broadened to meet specific application requirements and/or to enhance desirable properties. In preferred embodinent (c) X and R1 are as defined previously, y is an integer from 1 to 4, and Y is a surfactant anion. For the purposes of describing the above compounds, throughout this disclosure and in the claims the term "ar-vinyl phenylenylalkylenyl" is intended to encompass all vinylphenylenyl compounds irrespective of the position of the vinyl group on the ring structure, as well as those compounds in which one or two of the four hydrogen atoms attached to the phenylene ring carbons are replaced by members of the group consisting of lower alkyl, iodo, bromo, chloro, lower alkoxy, dihydrocarbylamino,carbohydrocarbylamino,hydrocarbylOxy and carbonyloxy groups to the extent that such groups do not interfere with the general characteristics of the compounds, particularly the ability to form addition copolymers and the ability of such copolymers to crosslink for the purposes described subsequentially herein. further embodiment A preffered of the invention is that in which the vinylphenylenylalkenyl group is vinylbenzyl i.e., where y in the above formula is 1, R is methyl, X is chloro and Y-is surfactant anion. ---- - The surfactant anion used in the/ invention is an anion which is surface active in water, that is, it is an anion which concentrates at the air-water interface and thereby lowers the surface tension of the water. Many such anions, i.e., the anionic portion of an "anionic surface active agent", are on to those skilled in this art. Among the classes of surfactant anions that are useful in this invention are those given. in the classification scheme on pages 15 and 16 of Schwartz and Perry, Surface Active Agents Interscience Publishers 1949, As used herein the term "surfactant anion" embraces mixtures of surfactant anions including commercial materials which often are mixtures of-species varying in hydrocarbyl chain length. Among the useful surfactant anions are those which are relatively hydrophilic in the hydrophilelipophile balance classification of surfactants. Many types of anionic surfactants are known, and are generally classified by the chemical nature of the anion; particularly useful examples are the sulfuric esters or sulfates joined directly or through an intermediate linkage to a hydrophobic group, alkane sulfonic acids-with the sulfonic or sulfonate linked directly to a hydrophobe or linked through an intermediate linkage such as an ester or an amide or ether linkage, alkyl aromatic sulfonic acids again either directly or indirectly linked, phosphates or phosphonic acids, thiosulfates, sulfonamides, sulfamic acids and so forth. Preferred anions are alkyl sulfates having an alkyl group of 6 to 20 carbon atoms, such as lauryl and myristyl sulfates; aromatic sulfonates of 8 to 24 carbon atoms, such as dodecylbenzenesulfonate ; alkyl and alkaryl oxyethylene sulfates having up to 10 oxyethyiene units wherein the alkyl group has at least 8 carbons and may have up to a number corresponding to 20 plus the number of oxyethylene units in the anion; and dialkyl sulfosuccinates having a total of 6 to 30 carbon atoms in the two alkyl groups. The most preferred anions are dodecylbenzenesulfonate , lauryl sulfate, myristyl sulfate, tridecyl sulfate, dioctyl sulfosuccinate,diisobutyl sulfosuccinate and dioctyl phosphate. The various anionic surfactants are usually commercially available as alkali metal salts, ammonium salts or salts of low molecular weight amines. The lipophilic salts (I) and (IV) are prepared by mixing a water-immiscible organic solvent, water, a quaternary ammonium monomer salt and an anionic surfactant salt. The water immiscible solvent may be a ketone, alcohol, ester, aromatic hydrocarbon, but preferably is a vinyl monomer, such as an acrylate or methacrylate ester or styrene. For the best yield of liposalt the quaternary ammonium salt and the anionic surfactant salt should be mixed at equal equivalents or approximately so. After mixing the ingredients, two liquid phases result. The organic phase contains the liposalt (I) or (IV) generally in a yield and purity greater than 80% preferably 90% or even 95%. The aqueous phase contains, as the principal component, the- (usually inorganic) water-soluble cation from the anionic surfactant and the-(usually inorganic) water-soluble anion from the quaternary ammonium component. These watersoluble ions are not micelle-forming ions nor do they exhibit the marked tendency to concetrate at the surface of water as is characteristic of surfactant anions. When the liposalt is to be used as a comonomer in an emulsion polymerization, the preferred solvent would be one of the other comonomers Although it is not necessary to separate and remove the aqueous layer containing the inorganic salts, its separation may be preferred in order to prepare an emulsion copolymer free of extraneous salts. Such salts frequently are detrimental to the properties of the ultimate polymer film because of increased water sensitivity. As used herein "lipophilic salt (I) or (IV)" and "quaternary liposalt" are synonymous. The term "lipophilic" being that used in the field of colloid science to denote "oil-loving" or oil soluble materials. The following comments are theoretical only and may be useful in understanding the utility of the monomers of the instant invention, particularly as regards their incorporation into polymers in emulsion copolymerization. They do not however limit the scope of this invention is any way. Tne monomers s are oil Solo toe ana comparatively insoiuoie in water so despite their anionic surfactant content these monomers do not behave as surface active agents. This is believed to be due to the shielding of the charged regions of the salt by the surrounding organic groups, that is the four organic groups surrounding the nitrogen atom and. the large hydrocarbon attached to the charged region of the anion. Thus the monomers tend to distribute into the organic phases present in an emulsion polymerization, i.e., into the monomer particies in the monomer emulsion and the polymer latex particles in-the polymer emulsion and in both of these during the polymerization. Compared to any of the surface active agents normally employed in emulsion polymerization these monomers do not concentrate effectively at the interface between the aqueous phase and the growing polymer particle. The presence of these monomers in the growing latex polymer particle is believed to have the very important result that the crosslinking quaternary monomer becomes incorporated uniformly into the polymer; as opposed to being substantially on the polymer particle surface. The quaternary monomer,being a relatively expensive monomer, its more effective use, due to uniform incorporation, particularly its not being essentially lost as watersoluble polymer, leads to bdth better crosslinking and lower cost. The liposalt monomers of the present invention are - - on organic Solvents soiuDie/ ana water insoluble in general. Thus, the quaternary ammonium liposalt monomers are readily employed in organic solution polymerizations, and are particularly well adapted to polymerization processes in which it is desirable to form a mutual solution of some or all of the monomers before polymerization. This solubility property. is particularly advantageous in bulk polymerizations, where it is desirable to form a solution of the monomers1 as well as in suspension polymerization. In the case of emulsion polymerizations, the quaternary ammonium monomers of the prior art tend to segregate during polymerization so as to give quaternary ammonium-rich polymer fractions with higher water solubility than the remainder of the polymer. These water rich fractions contribute to water sensitivity of the final products, such as coatings, binders or adhesives made from the polymer emulsion. It is particularly noteworthy that the low energy cure characteristic of the functional quaternary ammonium mer units of the polymer made from monomer of the present invention is retained. The quaternary ammonium monomers of the present invention are polymerizable, and for this purpose, their solutions may be used directly. Any known polymerization initiator of the free radical type can be used. Examples are t-butyl hydroperoxide, ammonium persulfate, and alkali metal persulfates, such as those of sodium or potassium. They are used at the customary dosages such as 0.1 to 2% by weight based on monomer weight. They may be used with sodium hydrosulfite or other reducing agents in redox systems Alternatively, the polymerization may be effected by actinic radiation. Emulsion polymerization procedures are particularly effective for polymerization of the low energy cure quaternary ammonium monomers of the present invention. As emulsifiers in the emulsion polymerization any of the commonly used nonionic surfactants may be employed, such as the alkyl phenyl poly ethoxy ethanols having from about 10 to 50 or more oxyethylene unit and any of the anionic surfactants, preferably the species listed above. The use of the comparatively inexpensive anionic surfactants as emulsifiers with the quaternary ammonium liposalt monomers offhis instant invention further distinguishes these monomers from the quaternary monomer of the prior art. The prior art monomers, not being liposalts, were generally employed with nonionic surfactants or cationic surfactants. The anionic surfactant stabilized emulsion polymers of this invention can known commercial or course De mixes with : anionically taoiiizeci emulsion polymers to achieve specific properties and various synergistic effects. One or more ethylenically unsaturated monomers having a group H2C=C may be polymerized with. the quaternary monomers of the present invention, under conditions such that the polymerization medium is maintained moderately acidic, preferably in the pH range 4 to 7. Thus by this method, it is possible to produce homopolymers and/or copolymers of the present quaternary monomers with the quaternary monomers of the aforementioned U. S. Patent 3,702,799 beginning in Column 4 at line 51 and continuing through line 22 of Column 5, In identifying suitable vinyl systems for reaction with the quaternary ammonium liposalt monomers care should be paid to the reactivity ratios of the monomers and/or to the Q and e values as determined in accordance with the Alfrey-Price Qe scheme as explained in Free Radicals In Solution and the Polymer Ilandbook as given above. Utilizing this type of information a proper choice of embodiment of this invention can be made from its pected relative reactivity ratios rl and r2 and that of the vinyl monomers. It is preferred that the relative reactivity ratios of the liposalt monomer and the comonomers should differ by no more than a factor of 10 and neither should be 0. Clearly the Q and e values of the quaternary ammonium liposalt monomer should be similar to those of the vinyl monomers used to form a copolymer. The quaternary ammonium liposalt monomers of the present invention can be homopolymerized but advantages in their use are obtained in copolymerization which employs the excellent organic phase solubility charactertistic of these monomers. Among the preferred monomers used with the quaternary ammonium liposalt monomers are acid and acid anhydride monomers. Ordinarily the use of acid monomers (anionic) in copolymerization with quaternary ammonium monomers (cationic) is avoided however in the present invention these are among the: preferred polymer compositions. Preferably the amount of acid comonomer employed is less than or about equal to the amount of quaternary ammonium monomer, on a molar basis, but in some instances a molar excess of acid is desired. The acids may be any of the < , O -unsaturated acids, such as the monocarboxylic acids, preferably acrylic, methacrylic, crotonic and half esters of maleic and fumaric, with acrylic and methacrylic being most preferred; as well as polycarboxylic acids such as maleic, fumaric and, preferably, itaconic. he cuaternary ammonium liposalt monomer content ic, by weight, usefully up to lC0% with the ranges 90 to 100% and 0.2 to 50% being preferred 0.5 to 10% more preferred and 1 to 5% most preferred. The carboxylic acid monomer content is by weight, preferably up to 5%, more preferably 0.1 to 18. A surprising feature of the copolymers made from the can monomers or units invention is tnat many/exniit little, it any, cationic character. Therefore, despite the polymers having cationic mer units, they may be compounded with commonly used anionic materials (such as pigments, thickeners, dyes, fillers, etc.) without coagulation, excess thickening, grease formation or, other signs of unacceptable stability on storage. In certain applications however it may be desirable that the polymers exhibit cationic character. This may be achieved by employing quaternary ammonium monomers which are not liposalt monomers,in addition to the liposalt monomers of formula I, in the preparation of the polymer. In general it is perfectly feasible to employ the formula I monomers in conjunction with other quaternary ammonium monomers, including: those which have the same cation as the monomers of this invention but do not have a surfactant anion; those which have a surfactant anion and a quaternary as used in ammonium cation not/ this invention; and those quaternary ammonium monomers different both with respect to anion and cation - -- - - ,used in the present ,, - erom nose, invention. ur course tnese various otner quarternary ammonium salts do not contribute to the advantages of the present liposalt monomers, particularly the low energy cure characteristics and solubility in organic solvents and monomers. Yarples OL quaternary ammonium monomers which may be employed among the comonomers in preparing the polymers of th is invention are those of Silvernail et al taught in U. S. Patent 3,011,918 column 2, lines 17 to 37 as "...vinyl- benzyl quaternary ammonium compounds having the gneral formula EMI19.1 wherein R, R' and R" each represents individually a monovalent radical being one of the following: CH2OHCH2 CH3CHOHCH2, CH2OHCHOHCH2- and alkyl, aryl cycloalkyl and aralkyl hydrocarbon radicals, and R, R' and R' collectively represent the trivalent radical of the formula: EMI20.1 wherein the three valences are attached to the nitrogen atom, the said R group containing a total of not more than 12 carbon atoms in the sum of the constituent radicals, ..."; "; those of Fordyce et al, taught in U.S. Patent 3,023,162, as the mer unit present in the polymer, column 2, lines 10 to 31 as "...quaternary unit having the structure of the formula: EMI20.2 where R is H or, preferably, CH3.

Examples of these negative radicals include halides, such as chloride, bromide, and iodide, sulfate, e.g., the methyl sulfate anion, acetate, tartrate, propionate, citrate, phosphate, and so on."; and those of Samour et al in U. S. Patent 3,861,948, column 1, line 65 to column 2, line 23 having the formula EMI21.1 in which R represents hydrogen or methyl; R1 represents an alkylene group having 2 to 12 carbon atoms including ethylene, propylene, butylene, hexylene and decylene or R1 represents a 2-hydroxypropylene group; R2 and R3 each independently represents an alkyl group having from 1 to 4 carbon atoms; R4 represents (a) an alkyl group having from 1 to 6 carbon atoms, or (b) a group having the formula EMI21.2 in which R5 represents hydrogen or an alkyl group having from 1 to 6 carbon atoms, or (c) a group having the formula -CH2-Y in which Y represents -CONH2, -COOH, or -COOR6 in which Rg represents an alkyl group having from 1 to 6 carton atoms; and in which X represents Cl Br, or -SO4R7, where R7 represents methyl, ethyl, or tolyl. Many other quaternary compounds will be recognised by the skilled man to be useful. this Polymers of the compounds according to/ invention offer wide utility because of their ability to further polymerize and to crosslink via self-reaction and also because of their ability to react with a wide variety of other materials. Activated epoxide groups are well known to those skilled in the art to be reactive with many coreactants, particularly with those with replaceable hydrogen, such as alcohols, acids, primary and secondary amines, phenols, etc. The polymers are particularly appropriate when used, alone or formulated, in industrial applications such as in binders, coatings and adhesives. The polymers are particularly useful in clear or pigmented coatings for use on soft substrates, such as vinyls, leather and paper, as well as on hard substrates such as wood, metal, mineral and road surfaces. The coating, in these uses, serves the various well known decorative and protective purposes, such as wear resistance, solvent resistance, detergent resistance, abrasion resistance, appearance improvement, etc. As pigment print binders, the polyers are useful in printing inks which furnish durable design or decoration for woven or non-woven fabrics, films, rigid panels, etc. Fibers of either synthetic or natural materials, such as polyolefins, polyesters, rayon, nylon, fiberglass, wood, wool, etc., may be bonded by means of these polymers to furnish non-woven fabrics, particularly those of high durability for uses such as clothing interliners, fiberfill insulation, filter material, diaper components, and various forms of wearable and decorative fabrics. Used alone or in formulations, these polymers offer strong and durable adhesives particularly useful for the lamination of fabrics, woven or non-woven, films, hard panels, foamed materials, and the like, in any combination to form two-layer or multilayer laminates. Employed as a flock adhesive, or a component thereof, the polymer serves to adhere fiber flocks of materials such as nylon, polyester or rayon to a substrate, such as fabrics, either woven or non-woven, rigid panels and foams. Towels, wipes and other paper products with good mechanical strength and water resistance are made by binding wood fibers, or mixtures of these with other fibers emDlovina the present of these polymers polymers as binders.

Emulsions, 100 g. at 50% solids, are treated with 109 sodium hydroxide (0.5-1.0 g), except for Example 4A which is treated with four parts of 15% sodium sesquicarbonate; all represent anexcessof base over the stoichiometric requirement for activation. About 0.8 g. of the treated emulsion is applied to a spot plate cavity and allowed to air dry and cure for one week at room temperature. The cured pellets as made are allowed to swell for four days in 25-40 g. of portions dimethylformamide (DMF) and chlorobenzene (C6H5Cl) to determine the volume swelling ratio and the solvent soluble fraction. Results are summarized in the following table. Both the lower volume swelling ratio and lower solvent solubles shown in the copolymer for 4B and 4C demonstrate the superior crosslinking achieved by quaternary liposalts even when they are present in the copolymer composition at a lower concentration.

Example 8 - Preparation of Glycidsl Liposalts of Formula (IV) A flask is charged with 100 g. water and 161 g. (1.0 mole) p-vinyl-N,N-dimethylbenzylamine, cooled to 150 C., and 90 g. of 67% HNO3 charged gradually to bring the pH to 7.0. Epichlorohydrin, 100 g. (1.09 moles), is added over two hours to the reaction mixture at 250 and at a pH of 7 to 7.5. The pH being maintained by periodic additions of sodium carbonate or nitric acid. After 24 hours the reaction mixture is concentrated to dryness to yield 320 g. of a syrup containing 3.25 meq./g. of combined chloride. This syrup is the quaternary ammonium nitrate. In a similar way dimethylaminopropylmethacrylamide is treated with nitric acid and epichlorohydrin to form its adduct, another quaternary ammonium nitrate. To 32 g. (0.1 mole) of the benzylammonium quaternary prepared above, dissolved in 300 g. of 80 acetone/20 water, is added 25 g. of potassium carbonate and the mixture stirred for 24 hours. Twenty grams of a lower aqueous layer is withdrawn, the top layer washed with 15 g. H20 and concentrated to a 34.8% solids solution which is found to contain 0.31 meq./g. of chloride ion, 0.015 meq./g. of combined chloride and 0.96 meq./g. of epoxide (by addition of HC1 in ethanol/water and magnesium chloride). In a similar way the quaternary ammonium halohydrin of dimethylaminopropylmethacrylamide is converted to a glycidyl quaternary ammonium salt. In the manner of Example 1 the two glycidyl qua ternary ammonium salts are converted to DDBS liposalts as solutions in ethyl acrylate. Following the same procedure other monomers, butyl acrylate, styrene, vinyl acetate, vinyl chloride and methylmethacrylate, are substituted fqr the ethyl acrylate to produce a liposalt in solution in the given monomer. Example 9 - Preparation of a Solution Polymer A monomer-initiator mixture is prepared from 200 g. of ethyl acrylate, 25 g. of a 20% ethyl acrylate solution of CH-DMA dodecylbenzenesulfonate, 3.0 g. t-butylperoctoate and 125 g. toluene. A flask equipped with a thermometer, a Dean-Stark trap, a condenser, a stirrer and an addition funnel is charged with 100 g. toluene and 50 g. of the monomer-initiator mixture. The flask contents are blanketed with nitrogen, heated to reflux (1100 C.) and the remainder of the monomer-initiator mixture fed over 2 hours. At the end of the polymerization a change of 1.0 g. t-butylperoctoate is made to decrease the level of unreacted monomers. Several grams of water originating from the liposalt solution is collected in the Dean-Stark trap. The polymer solution has 15.7 Ns/mi - ' - - - - a viscosity oft;5,700 cpsSand a solids of 49.5%. Using the same process, solution polymers are prepared from the glycidyl quaternary ammonium dodecylbenzenesulfonate of Example 8 derived from p-vinyl-N,N-dimethylbenzylamine by copolymerization of one part with ten parts, by weight, of vinyl acetate. The dimethylaminopropyl methacrylamide based quaternary ammonium liposalt, as prepared in Example 8,is solution copolymerized with styrene and butyl acrylate, ten parts of each of the latter to one of the liposalt to furnish a hydrophobic copolymer with a well incorporated quaternary ammonium salt. The incorporation in such a polymer is one of the unique features of the monomers of this invention, in addition to which the polymer is readily crosslinked. Example 10 - Emulsion Copolymer of Glycidyl Quaternary Ammonium Liposalt In the same way as in Example 2 an emulsion polymer with EA is prepared from the glycidyl quaternary ammonium dodecylbenzeneosulfonate salts derived from p-vinyl N,N-dimethylbenzylamine and N,N-dimethylaminopropyl- methacrylamide (Example 8). Emulsion polymerization ofthese glycidyl monomers of Formula (IV) is carried out in the pH range between 2 and 8, preferably between 4 and 7 to produce glycidyl-functional polymers. These polymers are utilized to prepare crosslinked polymers useful as binders, coatings and adhesives, i. e., useful as adherents to substrates. Example 11 - Copolymer Used as a Paper Binder Employing the process of Example 2, a polymer is prepared having the composition 98.1 EA/1.8 CH-DMA DDBS/0.lAA. A second polymer having the same composition, is prepared by a thermal reflux emulsion polymerization process. Roll towels employing these polymers as binders are prepared and tested as follows: Procedure: 1. Cut two 18" lengths of P4 Whatman Chromatographic paper per sample. 2. Condition at 720F. and 50% R.H. for 24 hours. 3. Weight conditioned paper to obtain tare weight. 4 Activate polymers one hour prior to use by adding 5% of a 15% sodium sesquicarbonate solution based on total volume of emulsion. 5. Prepare 400 gms (1 pint) of binder at desired solids. 6. Dip the paper in the binder and feed through rollers in Birch padder. Lay damp paper out flat to dry for one hour. 7. Condition saturated samples at 720F. and 50% R.H. for at least 8 hours. 8. Cure all sheets at 2400F. for one minute. 9. Condition sheets at 720F. and 50% R.H. for 24 hours to allow for moisture pick-up. 10. Cut each sheet to sixteen 1" x 6" strips, eight for dry tensiles and eight for wet tensiles. 11. For both dry and wet tensiles use Model 1130 Instron tensile test machine. Set up Instron as follows: Gap between jaw: 4 inches Cross head speed: 2 inches per minute Calibration: 50 lbs. full scale load for dry tensile. 50 lobs. full scale load for wet tensile. 12. Elongate all samples to break. Immerse the wet tensile strips in 1% Aerosol OT solution for about 15 seconds. 13. Read and record maximum stress of each sample to the nearest 0.1 pound. Report the average of the eight replicates as the wet and dry tensile strength in pounds per inch of width. The paper utilizing the redox prepared polymer has average tensile strengths of 2.9 lbs./inch wet and 9.8 lbs./inch dry. The corresponding values for the paper made with the thermal reflux polymer are 2.4 and 9.8 lbs./inch.
