Abstract
PURPOSE: An expandable styrene resin particle, moldable at a shortened molding cycle, which is prepared in the presence of the glycerin ester of a fatty acid, on or near the surface of a styrene resin particle containing a volatile organic foaming agent.
CONSTITUTION: 0.05pts.wt. ester of a fatty acid and glycerin, consisting of a mixture of a monoglyceride and 30W90wt% triglyceride, is allowed to be present, on or near the surface of the main portion of an expandable styrene resin particle containing 100pts.wt. styrene resin, 2W10pts.wt. volatile organic foaming agent and 0W 3pts.wt. plasticizer. Said triglyceride is defined to be compounded in 30W90wt%, because a proportion, except 30W90wt%, of the triglyceride exerts undersirable influene on some processes for obtaining a foam molded product. At least 0.05pts.wt. said ester is allowed to be present, because less than 0.05pts.wt. said ester is not effective for shortening molding cycle and deteriorates expandability.
