ABSTRACT:
Particle size distribution in elastomeric latex preparations is advantageously controlled and improved by treatment of the prepared latex with an agglomerating agent (AgAg) copolymer having an elastomeric "core" and grafted thereto a "shell" of interpolymer comprising polymerized acid and ester comonomers. The grafted interpolymer can beneficially be a polymerized mixture of ethyl acrylate and methacrylic acid. Agglomerated latex product can be recovered for direct utilization of its favorably particle size-distributed elastomeric component or for other purposes such as grafted polymer blends, ABS and similar products.
