Abstract:
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.
Abstract:
On enduit des polymères de styrène dilatables particulaires avec un produit de monoglycéride acétylé distillé, afin de réduire le temps de refroidissement de particules moulées à partir de tels polymères de styrène dilatables. On obtient le revêtement du polymère de styrène particulaire dilatable en mettant le polymère en contact avec une émulsion d'un monoglycéride acétylé distillé et de l'eau avec un tensio-actif approprié. Le monoglycéride acétylé distillé est un liquide à température ambiante et est sensiblement complètement acétylé.
