Abstract: Cross-linked dispersion copolymers are disclosed which are produced by the aqueous emulsion copolymerization of from 15% to 80% of vinyl acetate, and from 5% to 70% of polyethylenically unsaturated cross-linking agent, like hexane diol diacrylate, from 1% to 40% of other copolymerizable monoethylenically unsaturated monomer being desirably present, preferably from 5% to 25% of a reactive monomer which is desirably hydroxyl-functional. The dispersion copolymers are suspended in active organic solvents which extensively swell the copolymer particles. These suspensions are useful in thermosetting solution coating compositions where they provide improved thermal sag resistance.

Abstract: Aqueous thermosetting cationic electrocoating compositions are disclosed in which an amine-functional cationic polymer is dispersed in water with the aid of an acid, a curing agent being added if the polymer is not self-curing, and there is added from 1% to 30% of the polymer content of the composition of an oxirane-free epoxy phosphate. This epoxy phosphate is produced by slowly and incrementally adding a resinous polyepoxide to a solvent solution containing from 0.05 to 0.9 mole of orthophosphoric acid per oxirane equivalent in said polyepoxide together with sufficient water to hydrolyze all of the oxirane functionality which is not consumed by the orthophosphoric acid. When the epoxy phosphate is made in the manner set forth, the salt spray resistance of electrodeposited cured films is improved.

Abstract: A process of producing a water dispersible epoxy phosphate-solvent mixture is disclosed which comprises heating the solvent with orthophosphoric acid to reaction temperature together with additional water so that the total amount of water is sufficient to hydrolyze at least about 50% of the oxirane functionality in the polyepoxide which is used, slowly adding a resinous polyepoxide to this heated mixture so that reaction with phosphoric acid and hydrolysis of the oxirane groups will occur simultaneously to minimize the concentration of oxirane functionality in the reaction mixture as the reaction proceeds, thus minimizing epoxy-epoxy reactions which tend to increase the molecular weight of the epoxy phosphate which is formed, and then adding volatile amine to destroy any remaining oxirane functionality and to neutralize the epoxy phosphate to provide a water dispersible epoxy phosphate-solvent mixture.

Abstract: Monoethylenic monomers, including from about 1 to about 30% by weight of monoethylenic carboxylic acid, are placed in solution in a liquid mixture containing a low molecular weight polyhydric alcohol. This liquid mixture is dispersed in water and polymerized at an elevated polymerization temperature using agitation and in the presence of a free radical polymerization catalyst. The dispersion of polymer particles is then at least partially neutralized, preferably with ammonia or an amine to form an aqueous dispersion which is stable in the absence of emulsifying agent and which is useful in coating.
