Abstract

La invencion se refiere a un procedimiento para la obtencion de poliestireno expandible, en forma de perlas, por polimerizacion de estireno en suspension acuosa en presencia de 1 a 5% en peso de un hidrocarburo con 4 a 6 atomos de carbono y 0,5 a 33% en peso de un hidrocarburo alifatico saturado con un punto de ebullicion por encima de 7O°, pero en ausencia de un transferidor de cadena, que produce una reduccion del peso molecular de poliestireno.
