Abstract
In a method for producing a polymer composition by contacting PA0 A. a polymer component selected from the group consisting of chlorinated polyethylene and a mixture consisting of a major amount of chlorinated polyethylene and a minor amount of copolymer selected from an ethylene-propylene copolymer rubber an, ethylene-propylene-nonconjugated diene terpolymer rubber and an ethylene-vinyl acetate copolymer rubber, with PA0 B. a monomer mixture comprising PA1 B.sub.1. at least one of styrene, alpha-methyl styrene, tertiary butyl styrene and chlorostyrene, and PA1 B.sub.2. at least one of acrylonitrile and methacrylonitrile Under polymerization conditions to form an interpolymer of the components (A) and (B), the improvement which comprises suspending polymer component (A) and monomer component (B) in the form of fine particles in an aqueous medium.
