Abstract

PURPOSE: To obtain the titled particles having improved maintenance of a blowing agent, foamable in high magnification of expansion, having both elasticity and rigidity, by covering the surface of a polymer of vinyl monomer with a polyolefin resin containing the vinyl monomer.
CONSTITUTION: (A) Particles of polymer of vinyl monomer previously impregnated with (B) a blowing agent in gaseous or liquid state at normal temperature (preferably lower aliphatic hydrocarbon, e.g., propane, etc.), (C) polyolefin type resin powder, (D) the vinyl monomer or a mixture of the vinyl monomer and other vinyl monomer, and a crosslinking agent are subjected to suspension polymerization in an aqueous medium, to give the desired particles consisting of the component A as a core substance and the component C containing the polymer of the component D as a skin substance, having a weight ratio of core substance to skin substance of 95/5W30/70, and containing the component B.
