Vinyl acetate polymers and latex compositions containing same

摘要

Polymers having excellent adherence to film supports such as cellulose acetate are disclosed. The polymers comprise random recurring units having the structure -A)w, -B)x, -C)y and -D)z wherein; A represents polymerized vinyl acetate; B represents a polymerized acrylate or methacrylate monomer capable of copolymerization with vinyl acetate; C represents a polymerized monomer selected from the group consisting of methacrylic acid, itaconic acid and vinylbenzoic acid; D represents a polymerized cationically charged copolymerizable monomer; w represents from 20 to 85 weight percent; x represents from 5 to 65 weight percent; y represents from 5 to 50 weight percent and; z represents from 2 to 10 weight percent.
