Abstract

PURPOSE: To obtain the titled polymeric particles having improved tensile strength, fluidity in molding, compatibility with another polymer and appearance of molded articles, by impregnating olefinic polymeric particles with a vinyl monomer, and carrying out the aqueous suspension polymerization of the vinyl monomer with a specific radical polymerization initiator.
CONSTITUTION: (A) 100pts.wt. olefinic polymeric particles, e.g. homopolymeric or copolymeric particles of a 2W20C olefin, are impregnated with 80wt% or more (B) 5W200pts.wt. vinyl monomer, e.g. styrene or (meth)acrylic acid or methyl (meth)acrylate, in the presence of (C) 0.01W5wt%, based on the component (B), radical polymerization initiator (INT) consisting of 30W90wt% INT, e.g. tert- butyl peroxypivalate, having a decomposition temperature of 50W60°C for obtaining a half-life of 10hr and 70W10wt% INT, e.g. benzoyl peroxide, having the decomposition temperature >60°C in an aqueous suspension by heating at such a condition as not to decompose the component (C), and the impregnated polymeric particles are then heated at 50W100°C to complete the polymerization of the component (B).
