摘要： 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.

摘要： 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.

摘要： Low temperature curing aqueous coatings are provided in which the resin solids are constituted by an epoxy ester of a resinous polyepoxide with at least about 0.2 moles of monocarboxylic acid containing conjugated unsaturation and at least about 0.5 mole of monocarboxylic acid containing nonterminal nonconjugated unsaturation per equivalent in the polyepoxide. This epoxy ester is substantially free of epoxy groups and is copolymerized in solvent solution with monoethylenic monomers containing terminal unsaturation, including about 3% to about 20% carboxyl-functional monomers based on the weight of the copolymer to provide a nongelled, solvent-soluble copolymer possessing residual ethylenic unsaturation so that the copolymer can be dispersed in water with the aid of a base. These epoxy ester copolymers will dry and cure in air at room temperature. Also, and by including in the copolymer a proportion of monoethylenic monomer containing terminal unsaturation and providing a primary hydroxy group, the copolymer contains primary hydroxyl groups as well as carboxyl groups and residual unsaturation so that when aminoplast or phenoplast resin is incorporated in the water solutions, the applied coatings cure at remarkably low temperature to form solvent and corrosion-resistant coatings.
