EXPANDABLE STYRENE POLYMER PARTICLES, A METHOD OF PRODUCING THE PARTICLES AND FOAMED STYRENE POLYMER ARTICLES OBTAINED FROM THE PARTICLES

摘要

Expandable styrene polymer particles which have fast cooling rates during molding are produuced by suspending styrene polymer particles in an aqueous medium and impregnating a blowing agent into the particles in the presence of 0.1 to 0.6 parts of a synergistic mixture of surfactants per 100 parts of polymer particles.
