POLYMER PARTICLE COMPOSITION AND PROCESS FOR PRODUCING THE SAME

摘要

Rigid thermoplastic polymer particles for molding which can eliminate all of the problem concerning fine particles attributable to suspension polymerization processes, problem concerning the reduction of energy consumption for drying peculiar to emulsion polymerization processes, and problem concerning compounding operation by processors. The thermoplastic polymer particles for molding are obtained by coating 100 parts by weight of polymer particles produced by suspension polymerization which have a glass transition temperature of 60~C or higher and an average particle diameter of 50 to 500 ~m with 5 to 22 parts by weight, excluding 22 parts by weight, of a polymer produced by emulsion polymerization.
