Abstract

PURPOSE: To prepare truly spherical styrene resin particles capable of giving improved fusion and surface conditions of molded articles, by polymerizing a specific crosslinking agnet and a vinyl monomer in the presence of small pieces of styrene resin in an aqueous medium, and by impregnating the polymer particles with a blowing agent.
