Abstract

La invención se refiere a un procedimiento para la polimerización de {al}-olefinas en fase gaseosa a una temperatura que varía desde 30 a 150 ºC y a una presión de entre 5 y 80 bares, con una mezcla de catalizadores que contienen, como agente antiestático 0,1-5% en peso de ZnO y/o MgO libre de agua respecto de la mezcla catalítica total. El procedimiento de la invención excluye un procedimiento según el cual la mezcla catalítica contiene un catalizador de cromo y un catalizador de Ziegler a base de MgO modificado con n alqueno y un hidruro de alquilaluminio y que contiene MgO libre, el volumen de MgO total no debe ser menor del 2% en peso de la mezcla del catalizador.
