An aqueous latex of a vinyl ester polymer is described which has the property of forming self-curing films without the use of an extraneous curing additive. The latex is useful as a binder, particularly for non-woven fibers, or for wood panel coating or textile coating. The polymer comprises a major proportion of a vinyl ester monomer, typically vinyl acetate, which is interpolymerized with ethylene, a minor amount of a synergistic combination of cross-linking reactive comonomers, typically N-methylolacrylamide and diallyl maleate, and a cure-catalyzing amount of an ethylenically mono-unsaturated carboxylic acid such as acrylic acid. The polymer is dispersed in an aqueous emulsion using an anionic or nonionic surfactant or mixtures thereof, typically a mixture of an alkaryl polyether alcohol and an alkali metal sulfosuccinate half ester of an ethoxylated alcohol.
