Title (EN) OLEFIN POLYMERIZATION CATALYST SYSTEM
(FR) SYSTEME DE CATALYSEUR DE POLYMERISATION D'OLEFINES
Abstract: front page image
(EN)A catalyst system comprises 1) a group 4 organometallic catalyst and 2) an activator comprising a solid zirconium acid component and a metal alkyl. The catalyst system is inexpensive and is highly active for the polymerization of olefins. Preferred organometallic catalysts contain a cyclopentadienyl ligand, a phosphinimine ligand and or a ketimide ligand.
(FR)La présente invention a trait à un système de catalyseur comportant : 1) un catalyseur organométallique de groupe 4 et 2) un activateur comprenant un constituant d'acide de zirconium solide et un alkyle métallique. Le système de catalyseur est peu coûteux et présente une activité élevée pour la polymérisation d'oléfines. Les catalyseurs organométalliques préférés contiennent un ligand cyclopentadiényle, un ligand phosphinimine ou un ligand cétimide.
