Abstract

PURPOSE: The titled composition preventing aggregation in preexpanding and not inhibiting fusion between particles in molding, obtained by coating the surface of expandable styrene polymer particles with higher fatty acid ester of dipentaerythritol, etc.
CONSTITUTION: The surface of expandable styrene polymer particles containing 1W 10wt% aliphatic hydrocarbon having a boiling point not higher than a softening point of the styrene polymer particles as a blowing agent is coated with 0.01W 3wt% based on the expandable polymer particles of higher fatty acid ester of dipentaerythritol or higher fatty acid ester of sorbitan having two or more remaining hydroxyl groups in one molecule, and a higher fatty acid amide.
