The invention relates to a method for producing polyolefins by polymerizing olefins at pressures ranging from 0.5 to 3,000 bars and at temperatures ranging from -60 to 300 ~C in the presence of a metallocene carrier catalyst. To this end, a metallocene carrier catalyst is used containing the following active constituents: a) a metallocene complex and b) a metallocenium ion forming compound selected from the group consisting of Lewis acids and ionic compounds with non-coordinating anions.
L'invention concerne un procédé de préparation de polyoléfines par polymérisation d'oléfines à des pressions comprises entre 0,5 et 3000 bar et à des températures de l'ordre de -60 à 300 ·C, en présence d'un catalyseur métallocène sur support, le catalyseur sur support utilisé contenant comme constituants: A) un complexe métallocène, B) un composé générateur d'ions métallocène, sélectionné dans le groupe comprenant des acides de Lewis et des composés ioniques avec des anions non coordonnants.
