Abstract: Methods are disclosed for the production of a water dispersible solution of acidic copolymer in water soluble polyol with controlled limited reaction between the copolymer and the polyol. This method comprises copolymerizing monoethylenically unsaturated monomers including a proportion of carboxyl-functional monomer providing dispersibility in water with the aid of a base and from 0.5%-5%, based on the total weight of monomers, of a monoethylenically unsaturated monomer carrying a reactive group selected from dicarboxylic acid anhdyride functionality and N-methylol functionality, the copolymerization being carried out in solution in a water soluble polyol. This copolymerization is preceded by or carried out under conditions causing substantially complete reaction between the anhydride or the N-methylol functionality in the reactive monomer, and the hydroxy groups in the polyol. Aqueous coating compositions are provided by dispersing the copolymer solution in water with the aid of a volatile base.

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.

This copolymer can be dispersed in water with the aid of a volatile base and aminoplast or phenoplast resin can be incorporated.

Abstract: 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 mole of monocarboxylic acid containing conjugated unsaturation per epoxy equivalent in the polyepoxide and at least about 0.5 mole of monocarboxylic acid containing nonterminal nonconjugated unsaturation per epoxy equivalent in the polyepoxide.
