Abstract
PURPOSE: In the suspension polymerization in an aqueous medium, a water-- soluble high molecular dispersant and an alkylbenzene sulfonate salt as a foaming regulator are used to control the foam number in the foamed product and to give the titled resin particles giving moldings with high strength and smooth surfaces.
CONSTITUTION: In the production of foaming particles where the suspension polymerization of a styrene monomer is conducted in an aqueous medium in the presence or absence of a styrene resin and an organic foaming agent is added during the polymerization or the styrene resin particles, after the polymerization, are impregnated with the foaming agent, hard soluble inorganic substance are substantially removed from the aqueous medium, a water-soluble high molecular dispersant is added by 1×10-4W1wt% based on the resin particles, then the polymerization is effected and at an appropriate stage during the polymerization, an alkylbenzenesulfonate salt is added in the aqueous medium by 1×10-4W1wt% based on the particles. Or the alkylbenzenesulfonate salt may be added, when the resin particles are dispersed in the aqueous medium and the organic foaming agent is added.
