Abstract

Procedimiento para la obtención de una mezcla elastómero, termoplástico de poliolefinas, caracterizado porque a un 10-70% en peso de un caucho de etilen-propileno (EMP) ó bien de etilen-propileno-dieno (EPDM) se reticulan parcialmente mediante un peróxido, cuyo tiempo de valor medio a 140ºC es de cómo mínimo 10 minutos, como agente vulcanización, a una temperatura de 80-24ºC, de manera que el contenido en gel ascienda a un 2-25% en peso y a continuación, este producto así obtenido se hace reaccionar con b) un 30 ¿ 90% en peso de poliolefina.
