Abstract
A process for preparing improved molding materials of expandable styrene polymers by coating the particles with glycerin esters of long-chain fatty acids. The coating comprises organosols of pulverulent glycerin esters having 14 to 24 carbon atoms in aliphatic hydrocarbons having 3 to 8 carbon atoms. The proportion of glycerin monoester is at most 40, but not less than 10% by weight and the particle size of the pulverulent ester is less than 100 microns. The molding materials are used to manufacture molded articles.
