摘要
A pastable emulsion polymer comprised of carboxylated monomer/vinyl chloride/vinyl acetate terpolymer having improved strength of adhesion produced by emulsion copolymerization and containing, per polymer weight, from 60% to 98% by weight of vinyl chloride monomer units, from 1% to 29% by weight of vinyl acetate monomer units, and from 1% to 15% by weight of carboxyl-containing monomer units selected from the group consisting of olefinically-unsaturated monocarboxylic acids, monoallyl esters of non-ethylenically unsaturated dicarboxylic acids, and monovinyl esters of non-ethylenically-unsaturated dicarboxylic acids. The terpolymers are manufactured by the copolymerization of vinyl chloride, vinyl acetate, olefinically-unsaturated monocarboxylic acids and/or monoallyl esters and/or monovinyl esters of non-ethylenically unsaturated dicarboxylic acids in an aqueous emulsion. The pastable terpolymers, after empasting are used for coating flexible sheet-like articles.
