Abstract
Expandable styrene polymer particles which have fast cooling rates during molding are produced by dry blending styrene polymer particles in the presence of 0.06 to 0.60 parts of a mixture of alkyl esters of fatty acids per 100 parts of polymer particles. The ester mixture may be added as sole fast cool agent or in addition to the known internal additives which impart fast cool properties.
