Description: TITLE POLYMERIC COMPOSITIONS, AND THE PREPARATION AND USE THEREOF TECHNICAL FIELD This invention relates to polymeric compositions that are highly functional polymers with a relatively high molecular weight and are substantially free of gelling. Moreover, when used in agueous solution they provide a relatively low solution viscosity. The invention also relates to the preparation of such polymeric compositions. The polymeric compositions of this invention are particularly useful as polymeric support resins or compatabilizing additives, or for use in overprint varnishes, inks, pigment dispersions, powder coatings, adhesives and the like. The invention also relates to a deglossed acrylic epoxy hybrid powder coating and method of preparing the same, a powder coating composition comprising the polymeric compositions of this invention, as well as 100% solids resin inks. BACKGROUND ART Polymeric compositions that are block copolymers having an A(BA) n structure are well known. For example, U.S. Patent No. 5,362,819 describes an ABA curable block copolymer with an A block that is an unsaturated polyester, preferably having a mono-, or less desirably a di-, hydroxyl, carboxylic or amine end group, and a B block that is a flexible polymer having a glass transition temperature (Tg) of 0°C or less. The flexible polymers are said to include those prepared from conjugated diene monomers, as well as polyethers or saturated polyester, which are linked to the A block by an ester, amide, urea or urethane group. U.S. Patent No. 4,347,339 describes a water soluble cationic block copolymer having a first polymer block having amino functional groups, a majority of which are quaternary amino groups, and a second polymer block having amino functional groups, a majority of which are not quaternary amino groups . The polymer blocks may be linked with bridges of other polymers, but are preferably linked by including a functional group such as a chloride or epoxide in the first polymer block that reacts with the amino functional groups of the second polymer block. U.S. Patent No. 4,851,474 describes a block copolymer comprising at least one polyester block and an elastomeric polymer block such as a polymer of one or more conjugated dienes. The elastomeric block is f nctionalized to incorporate only terminal functional groups, i.e., no more than 2 functional groups per polymeric block. U.S. Patent No. 5,008,334 describes resins containing an ABA block copolymer having an A block which is a reaction product of a diol and one or more diepoxides and a B block of an epoxy-capped, carboxyl- terminated polybutadiene or polybutadiene/acrylonitrile copolymer. .Amine resins which are prepared from a resin that is a mixture of (i) the reaction product of a diol and at least one diepoxide and (ii) the ABA block copolymer are used in electrocoating formulations. U.S. Patent No. 5,314,954 describes aromatic polyester-polystyrene block copolymers produced by the polycondensation of styrene polymers having terminal functional groups, e.g. hydroxy, amino or carboxyl groups, with an excess of aromatic dicarboxylic acid dihalides and then subjecting the resulting condensation product to interfacial polymerization with aromatic dihydroxy compounds. These aromatic polyester-polystyrene block copolymers are said to have a minimum of uncopolymerized styrene and to be useful for the preparation of optical instruments. Polyester block copolymers that provide an elastic yarn having a high elastic recovery and a high heat resistance are disclosed by U.S. Patent No. 5,384,184. The polyester block copolymer comprises (A) 30 to 90% by weight of polyester segments comprising a benzenedicarboxylic acid as the main acid component and a diol having 5 to 12 carbon atoms between the hydroxyl groups as the main glycol component and (B) 70 to 10% by weight of polyester segments comprising an aromatic dicarboxylic acid as the main acid component and ethylene glycol, trimethylene glycol, tetramethylene glycol or 1, 4-cyclohexane dimethanol as the main glycol component . U.S. Patent No. 5,496,876 describes a polyetheramide block copolymer constituted by the copolycondensation of polyamide polymers having reactive end groups with polyether sequences having reactive end groups. These polyetheramide block copolymers are blended with a styrene/diene copolymer to form thermoplastic polymeric compositions. U.S. Patent No. 4,180,528 describes an ABA type block copolymer having an A block that is an addition polymer and a B block that is a linear saturated polyester. The A block and B block are joined by addition polymerization. European Patent Application Publication No. 0687690/A describes a high temperature polymerization process to produce terminally unsaturated oligomers having relatively low molecular weights. It is further disclosed that the terminally unsaturated oligomers having a carboxylic acid group can be reacted with polyfunctional alcohols having two or more alcohol functionalities to form polyesters. There is, however, no disclosure of terminally unsaturated oligomers having relatively high functionality. One particular use of polymeric compositions is as 100% solids resin. 100% solids resin compositions have many possible applications. For example, powder coating processes are well known and are typically fusion-coating processes in that powder particles are fused or melted at some point in the process. Powder coating processes are often advantageous because of their essentially nonvolatile nature. The powder ("coating powder") used in the powder coating process is coated onto a substrate surface, melted or fused to form a continuous coating, and cooled to harden the resultant coating. The heat can melt the powder to consolidate the powder to a coating film, or can cause the powder to react together, as in a polymerization or curing process, to consolidate the powder to a coating film. One type of coating powder uses acid functional acrylic resins in its formulation. Such acrylic formulations are commonly formulated with epoxy to make what is known as acrylic epoxy hybrid powder coatings. An example of such an acrylic resin being used for this purpose is SCX-819, available from S.C. Johnson Polymer, Sturtevant, Wisconsin, which has found wide use in the appliance market. However, the use of acrylics could be extended into other powder coating applications with the development of 100% solids resin polymers that have improved flexibility, and improved polyester compatibility, and by finding ways to degloss acrylic hybrids without sacrificing mechanical properties . Another possible use of 100% solids resin compositions is as plastic additives. Plastics additives are commonly used in the polymer industry. Additives are used as compatibilizers, thickeners, plasticizers, coextrusion additives to improve extrusion rheology and extruded product properties. Solid resins have also been used as hot-melt adhesives. 100% solids resin inks are mixtures of pigment components dispersed or dissolved in 100% solids resin carrier components. 100% solids resin inks are commonly used in applications such as letterpress, dry offset, lithography and as toners for xerography. Polymeric compositions, e.g., block copolymers, that are highly functional, preferably having high acid functionality, as well as a high molecular weight, but which do not readily gel would be highly desirable, particularly for the uses described above. SUMiiARY DISCLOSURE OF INVENTION This invention is related to a polymeric composition comprising the reaction product of an A polymer which is an addition polymer having 3.5 or more reactive functional groups per polymer chain and a B polymer having about 2 to about 3 functional groups per polymer chain that are co-reactive with the reactive functional groups of the A polymer. Preferably, substantially all of the co-reactive functional groups of the B polymer are co-reacted. More, preferably, the reactive functional groups of the A polymer are condensation reactive functional groups. Generally, the molar ratio of A polymer to B polymer is about 3:1 to about 2:1.7. Preferably when the B polymer is difunctional then the molar ratio of the A polymer to B polymer, based on the number average molecular weight (Mn) of the two polymers, is about 2:1 to about 2:1.7. When the B polymer is trifunctional then the preferable molar ratio of the A polymer to B polymer is about 3:1. The condensation-reactive functional group is preferably selected from the group consisting of carboxyl, hydroxyl, epoxy, isocyanato, carboxyl anhydride, sulfo, esterified oxycarbonyl or amino. In a preferred embodiment, the A polymer has 3.5 or more carboxylic acid functional groups per polymer chain. Most preferably, this A polymer is a low molecular weight styrene/acrylic acid/α-methylstyrene polymer.

It is also preferable that the co-reactive functional groups of the B polymer are hydroxyl, epoxy, oxazolinyl or amino. The polymeric compositions of this invention are high functional polymers with a relatively high molecular weight that are unexpectedly free of gellirg or gel particles. These polymeric compositions have a broad molecular weight distribution which enhances their utility and performance characteristics. Another embodiment of this invention is directed to the use of the polymeric compositions of this invention as 100% solids resin compositions. Such 100% solids resin compositions include, without limitation, powder coatings, plastics additives, hot-melt adhesives, 100% solids resin inks and the like. Yet another embodiment of this invention is directed to a method of reducing gloss of a film prepared from an acrylic epoxy hybrid powder coating by the inclusion of the solid resin composition of this invention in the powder coating.

At least one of the ethylenically unsaturated monomeric units of the addition polymer must have a reactive functional group such as a condensation reactive functional group, preferably a carboxyl group, hydroxyl group, or epoxy group, most preferably a carboxyl group or hydroxyl group. Exemplary acid- functional ethylenically unsaturated monomers include but are not limited to aconitic acid, acrylic acid, beta-carboxymethyl acrylate, cinnamic acid, crotonic acid, fumaric acid, itaconic acid, maleic acid, methacrylic acid, and mixtures thereof. Also suitable are certain monomers that are said to contain so-called "latent" acid moieties, such as cyclic anhydrides.

The condensation reactive functional group is preferably a part of the ethylenically unsaturated monomer, although it may, if desired, be added to the addition polymer after formation of the polymer. Preferably, the addition polymer used as the A polymer in the present invention is an acrylic copolymer or a styrene/acrylic acid or styrene/ (meth) acrylic acid copolymer, more preferably a styrene/α-methylstyrene/acrylic acid copolymer. Generally, the preferred styrene/acrylic acid addition polymer is comprised of from 10 to 90% w/w styrene, and 10 to 90% w/w acrylic acid.

Another preferred addition polymer used as the A polymer is a hydroxy acrylate or methacrylate copolymer or a styrene/hydroxy acrylate or styrene/hydroxy methacrylate copolymer, more preferably a styrene/hydroxy acrylate (or methacrylate) /acrylate (or methacrylate) copolymer. Yet another addition polymer that may be employed as the A polymer in the polymeric composition of this invention are hyperbranched polymers such as disclosed in copending U.S. Patent Application [Docket No. J- 2583] entitled "Process for Producing Hyperbranched Polymers", the disclosure of which is incorporated by reference herein. Such hyperbranched polymers having terminal ethylenic unsaturation would preferably have 3.5 of more condensation reactive functional groups per hyperbranched polymer. Typically the addition polymer is a low molecular weight polymer between about 500 to about 50,000 Mn, preferably about 900 to about 3,000 Mn . As noted previously, the condensation-reactive functionality of the addition polymer must be at least 3.5 or greater, and is preferably between about 3.5 and about 20, most preferably between about 3.5 and about 10. The preparation of addition polymers is well known to those skilled in the art, and includes gas phase polymerization, solution polymerization, batch polymerization, continuous reactor or tube polymerization, suspension polymerization and emulsion polymerization. Methods of preparing such addition polymers are described in U.S. Patent No. 4,413,370, U.S. Patent No. 4,529,787 and . U . S . Patent No. 4,546,160, the disclosure of each of which is incorporated by reference herein. The B polymer of the polymeric compositions of this invention has about 2 to about 3 functional groups that are co-reactive with the reactive functional groups of the A polymer. The preferred functional groups of the B polymer include: hydroxyl, carboxyl, epoxy, oxazolinyl and amino groups, although any group that is co-reactive with the reactive functional group of the A polymer is contemplated within the scope of this invention. The B polymer may be an addition polymer or condensation polymer, but preferably is a condensation polymer. The condensation polymer may be a polyamide, polyester, poly (ether), polyurethane or the like. The preparation of condensation polymers, like that of addition polymers, is well known to those skilled in the art. For example, polyesters may be prepared using common techniques of fusion processes with a glycol excess along with a tin catalyst. Polyamides may be readily prepared using a fusion process, without catalysis. The preparation of polyesters or polyamides generally requires the use of polycarboxylic acids. Exemplary polycarboxylic acids include, without limitation, adipic, azelaic, benzophenone tetracarboxylic dianhydride, 1, -cyclohexane dicarboxylate, chlorendic anhydride, di er acids, fumaric acid, glutaric acid, hexahydrophthalic anhydride, itaconic acid, isophthalic acid, maleic acid or anhydride, phthalic anhydride, sebacic acid, suberic acid, succinic acid, terephthalic acid, tetrahydrophthalic anhydride, trimellitic anhydride, alkanyl succinic anhydride, 5-sodiosulfoisophthalic acid, or 5-lithiosulfoisophthalic acid. Generally, the preparation of polyester glycols will employ components such as 1, 3-butanediol, 1, 4-butanediol, cyclohexanedimethanol, diethylene glycol, dipropylene glycol, 2, 2-dimethyl-l, 3-pentane diol, 2-butyl-2-ethyl- 1,3-propane diol, ethylene glycol, propylene glycol, pentaerythritol, trimethylol ethane, trimethylol propane, tris (hydroxy ethyl) isocyanurate, 1,6- hexanediol, 1, 5-pentanediol, triethylene glycol, tetraethylene glycol, hydrogenated Bisphenol A, glycerin, 2 methyl-1, 3-propane diol or the like. In the preparation of polyamides, the polyamine functional components typically may be chosen from ethylene diamine, hexamethylene diamine, 2-methyl-l, 5 pentane diamine, isophorone diamine, methylene dicyclohexyl amine, trimethyl hexamethylene diamine or the like. The starting acids are polymerized fatty acids, which are mixtures of monobasic acids (C18), dibasic fatty acids (C36) and trimer or polybasic fatty acids (C54 or higher) , dicarboxylic acids including aliphatic, cycloaliphatic, and aromatic dicarboxylic acids such as oxalic, glutaric, malonic, adipic, succinic, sebacic, azelaic, suberic, pimelic, terephthalic, 1,4 or 1, 3-cyclohexane, naphthalene, phthalic, isophthalic, dodecanedioic dicarboxylic acids. Preferred dicarboxylic acids are straight chain aliphatic diacids having at least 6 carbon atoms and more preferably 6 to about 22 carbon atoms such as sebacic, dodecanedioic, and azelaic dicarboxylic acids. Mono carboxylic acids may be added to control the molecular weight. Preferred monocarboxylic acids are linear and have 2 to 22 carbon atoms. Most preferred are stearic and oleic acids. The diamines used in the preparation of the polyamide may be one or more of the known aliphatic, cycloaliphatic or aromatic diamines having from about 2 to about 20 carbon atoms. Preferred are the alkylene diamines such as ethylene diamine, 1, 3-diaminopropane, 1, 4-diaminobutane, p-xylene diamine, 1, 6-hexamethylene diamine, cyclohexyl amine, bis (4-cyclohexylamine) methane, 2, 2 '-bis (4- cyclohexylamine) propane, polyglycol diamines, isophorone diamine, m-xylene diamine, cyclohexylbis (methylamines) , polyoxyalkylenediamine (sold by Huntsman under the trade name Jeffamine) , 2-methyl-1, 5-pentane diamine, 1, -bis- (2-aminoethyl) benzene, dimer diamine, polyether diamines, methylpentamethylene diamine, and piperazine. The preferred diamines are straight chained aliphatic diamines of 2 to about 20 carbon atoms, especially ethylene diamine and hexamethylene diamine, and cycloaliphatic diamines, especially 4-4 ' -methylenebis (cyclohexylamine) and piperazine. Mono amines may be added to control the molecular weight. Preferred mono amines are linear and have 2 to 22 carbon atoms. Most preferred are stearyl and oleyl amines. The condensation polymers may also include mono functional compounds to control functionality. For example, a mono acid such as benzoic acid, p-tertbutyl benzoic acid, veratic acid, rosin, lauric acid, fatty acids such as those made from soya, linseed, tall and dehydrated castor oils may be employed in the preparation of polyesters while mono amines such as stearyl amine, tallow amine and cyclohexyl amine may be employed in the preparation of polyamides. Preferred polyamide compositions employ nylon type monomers such as adipic acid and 2-methyl-l, 5-pentane diamine or dimer acid based monomers using dimer acid with isophorone diamine. Preferred polyester monomers include isophthalic acids and cyclohexyl dicarboxylates along with common glycols such as 3-methyl-1, 3- propanediol, 2, 2-dimethyl-l, 3-propanediol, and cyclohexane dimethylol. The polymeric compositions of this invention may be prepared by the polymerization of the previously described A and B polymers at a reaction temperate and for a time sufficient to form the polymeric composition. Preferably the reaction is a step growth polymerization reaction, i.e., a condensation polymerization reaction. Yet another embodiment of this invention is directed to the process of preparing the polymeric composition by reacting an A polymer which is an addition polymer having 3.5 or more reactive functional groups (preferably condensation reactive functional groups) per polymer chain with a B polymer having about 2 to about 3 functional groups per polymer chain that are co-reactive with the reactive functional groups of the A polymer. Preferably the reaction is conducted at a temperature and for a time sufficient to form the polymeric compositions by reacting substantially all the co-reactive functionality on the B polymer. Preferably, when the B polymer is difunctional, then the molar ratio of A polymer blended with the B polymer is about 2:1 to about 2:1.7. When the B polymer is trifunctional, then the molar ratio of A polymer blended with B polymer is preferably about 3:1. The preferred blending ratio when a mixture of difunctional and trifunctional B polymer is employed can be readily ascertained by those skilled in the art. The temperature and time of the reaction will depend on the A and B polymers. For example, if condensation of A and B is by esterification then the reaction temperature may reach 240°C or higher, while if condensation is through the formation of urethane linkages, then room temperature may be all that is necessary. The reaction temperature of the process for preparing the polymeric compositions is generally between about -50 °C to about 300 °C, preferably from about 150 °C to about 240 °C. The reaction temperature should not exceed the decomposition temperature of either the A polymer or the B polymer. Typically the reaction temperature is maintained from 0.5 to about 6 hours . If desired, solvents and catalysts may be employed in the preparation of the polymeric composition of this invention. The use of such solvents and catalysts is well known to those of ordinary skill in the art. It is important that the A and B polymers be compatible with each other to provide adequate mixing. If the polymers are not compatible, then solvent or staged addition of the polymers may be employed to overcome this. Solvents that are well known to those skilled in the art are also useful in controlling viscosity and permitting appropriate mixing when high temperatures can not be used. In addition, small amounts of solvent may be used for products of reaction such as xylene to azeotrope off water. The molecular weight of the polymeric compositions of this invention are generally broad. Both high weight average molecular weight (Mw) and z-average molecular weight (Mz) are possible, while the number average molecular weight (Mn) is typically not as high. The polymeric compositions of this invention are preferably high molecular weight polymeric compositions prepared from low molecular weight polymers in the substantial absence of gel. Without being bound to the theory, it is believed that the functionality of the reacting polymers is responsible for the absence of gel. The resulting polymeric compositions of this invention may take the form of block copolymer, e.g. ABA block copolymers. However, the polymeric compositions of this invention are not restricted to block copolymers, but may result, for example in highly branched or complex polymers that may not be considered block copolymers. Generally, the weight average molecular weight of the polymeric compositions of this invention range from about 4,000 to about 250,000, more preferably between about 5,000 to about 50,000 as measured by gel permeation chromatography using polystyrene standards. In addition, the preferred polymeric compositions having acid functionality typically have an acid number between about 40 to about 200. As will be apparent to one of ordinary skill in the art, the glass transition temperature (Tg) of the polymeric compositions of this invention can be readily varied by altering the monomeric make up of the A and B polymers. Typically the average Tg is -50°C to 120°C, although the end use generally dictates the type of Tg that will be sought. Industrial Applicability This invention is related to the preparation of industrially useful polymeric compositions. The polymeric compositions of this invention may provide improved properties over those exhibited by the A or B polymers alone or blends of the A and B polymers. The polymeric compositions of this invention may be used neat, in solvent, in water or, with appropriate levels of residual functional groups such as carboxyl groups, as polymeric supports for emulsion polymers, any of which may be useful as components of coatings, e.g. overprint varnishes or floor finishes, pigment dispersions, inks, adhesives or emulsion polymers. The polymeric compositions of this invention may also be used as plastic additives. Thus, yet another embodiment of this invention is directed to a method of compatabilizing one or more plastics by the addition of a compatabilizing amount of the polymeric composition of this invention thereto. The polymeric compositions of this invention may also be employed in a method of adhering two or more substrates by the application of the polymeric compositions to at least one surface of at least one substrate and joining the surface to a surface of a second substrate. The polymeric compositions may also be used as 100% solids resins. There may be used, for example, as powder coating compositions, hot melt adhesives, plastics additives, solid resin inks, for xerography and the like. Other related uses of the polymeric composition of this invention will be readily apparent to those of ordinary skill in the art. The powder coating composition of this invention comprises at least one polymeric composition as described herein, optionally a colorant or pigment and optionally a cross-linking agent. Preferably the pigment and cross-linking agent are present. Such colorants and cross-linking agents are readily available and known to those of ordinary skill in the art, as is their application in powder coating compositions. The powder coating composition of this invention may also include wetting agents, defoamers, UV absorbers, antioxidants and the like. 100% solids resin inks of this invention comprise the polymeric composition as described herein and a colorant or pigment. The colorant or pigments that are useful in the 100% solids resin inks of this invention are well known to those of ordinary skill in the art, as is their application in 100% solids resin inks. The 100% solids resin ink of this invention may be used by application of the resin to a substrate and melting said resin thereon. A particular use of such inks includes xerography. This invention will be better understood from the Experimental Details which follow. However, one skilled in the art will readily appreciate that the specific methods and results discussed are merely illustrative of the invention and no limitation of the invention is implied.

A number of additional polymeric composition were prepared using the A polymers described in Table A and the B polymers described in Table B below. Table A Table B Example I Preparation of a polymeric composition by Bulk Thermal Process A 1000ml four necked flask equipped with a stirrer, a nitrogen sparge tube, and a Dean Stark trap fitted with a condenser reactor was charged with 468g of a styrene acrylic polymer having carboxyl functionality (A polymer I) . This was heated to melt at 150-180°C. Then 140.4g of a branched polyester polymer having a primary (1°) hydroxyl (B polymer II) was added to achieve a mole ratio of 3A:1B.

The A polymer and B polymer constituents and properties of the resulting polymeric compositions for Examples I-XIV are set forth in Table C below. Table C 4 ND = NOT DETERMINED; AV = acid value Powder Coatings As shown below, when the polymeric compositions of the present invention were added to acrylic epoxy hybrid powder coatings the resulting powder coatings exhibited advantageous characteristics. In particular, such powder coatings prepared with polymeric compositions comprised of PPO (polypropylene oxide) as the B component were advantageous. The powder coating of this invention demonstrated an unexpected unique property of reducing gloss yet maintaining complete coating flexibility. Other methods commonly used to lower gloss tend to compromise flexibility. Existing gloss reducing techniques used in powder coating processes are unable to maintain flexibility without causing detriment to some other film property. With the polymeric compositions of the present invention, gloss can be lowered without compromising flexibility, hardness, corrosion, and U.V. resistance. Examples PC-1 to PC-5 were formualted with the polymeric compositions of this invention used as a modifier of an acrylic/epoxy hybrid coating powder. In addtion Comparative Exampels PC-CM-1 to PC-CM-5 were also prepared. The exemplary and comparative powder coatings are described in Tables Dl and D2, respectively, below. Table Dl Table D2 SCX-819 - acrylic resin available from S.C. Johnson Polymer, Sturtevant, Wisconsin. Shell 2002 - an epoxy resin available from Shell Oil Company, Houston, Texas. Modaflow III - flow agent available from Solutia, Inc., St. Louis, Missouri R-960 - Ti0 2 pigment available from DuPont de Nemours & Co., Wilmington, Delaware. NXJ-60 - catalyst available from Synthron, Morgantown, North Carolina. Joncryl 682 - an acrylic resin available form S.C. Johnson Polymer Resin L - a styrene acrylic resin similar to polymer A (1 ). The powder coating compositions were prepared in the following manner: First, all resins were preground in a Vitamix blender to reduce the particle size. Next, all ingredients were weighed together into a bag and vigorously hand shaken to mix. The premixed powders were extruded on a Buss PLK-46 extruder at a zone 1 setting of 60°C, and a zone 2 setting of 110°C. The extrudate was flaked in chill rolls, and broken up with a mallet. The flake was ground using a Bantam mill, .027 screen, equipped with liquid nitrogen cooling. After grinding, the powder was sieved using a 140 mesh screen. The powder was applied to Bonderite 1000 panels at varied film builds, and cured for 20 minutes at 190°C. The 60° and 20° gloss of the resulting coatings was measured using a Byk Chemie gloss meter. Impact was measured by direct "D" and reverse "R" impact techniques well known to those skilled in the art. Use of the polymeric compositions of this invention in the acrylic epoxy hybrid powder coatings was found to degloss, yet maintain physical properties in the coatings. The results show that levels in excess of about 4% were preferred, although lower levels may be used. The comparative examples (PC-CM-4 and PC-CM-5) made with only Joncryl 682 (an acrylic/styrene/α-methyl styrene resin available from S.C. Johnson Polymer, Sturtevant, Wisconsin) showed lower gloss but did not retain as much impact resistance, as the inventive compositions. Examples (PC-CM-1 and PC-CM-2) made with only polypropylene oxide did not degloss the acrylic hybrid. The example (PC-CM-3) made with both polypropylene oxide, and a styrene acrylic resin (Resin L) added separately showed slightly lower gloss, and reduced impact resistance. The results show that the polymeric compositions of the present invention are useful for deglossing acrylic epoxy hybrid powder coatings, particularly those compositions having a polymeric composition with a high acid number. The polymeric compositions of this invention were also used as a stand-alone binder for the preparation of powder coating compositions. Examples PC-6 to PC-9 are .described below in Table E. Table E Polym. Comp. A. A polymer Ex. 1 and B polymer of Esterdiol 204/CHDM/IPA with a molar ratio of 5/3/7 (42% Acrylic) Polym. Comp. B.

B NXJ-60 - catalyst available from Synthron, Morgantown, North Carolina. The results show that the polymeric compositions of this invention may be used in an epoxy hybrid powder coating composition as a stand alone binder. This is particularly surprising even with about 40% acrylic A polymer used in the polymer composition since it would be expected that a simple blend having that much acrylic A polymer would give very low gloss and very poor impact . Adhesives As previously discussed, the 100% solids resin polymeric composition of this invention may be used as a hot melt adhesive. The 100% solid resin adhesive compositions of the present invention were applied to the clay coated side of 18 point blister board. Tests of the coatings showed 100% fiber tear when the bond was pulled. A comparison polyester was so brittle that it would occasionally fracture when the bond was pulled. Other variations and modifications of this invention will be obvious to those skilled in the art. This invention is not limited except as set forth in the following claims.
