<p>Particulate expandable styrene polymers are coated with a distilled acetylated monoglyceride product to reduce the cooling time of articles molded from such expandable styrene polymers. Coating of the expandable particulate styrene polymer is obtained by contacting the polymer with an emulsion of a distilled acetylated monoglyceride and water with a suitable surfactant. The distilled acetylated monoglyceride is a liquid at room temperature and is substantially completely acetylated.</p> |
