(EN) CATALYST SYSTEM
(FR) SYSTÈME CATALYTIQUE
Abstract
(EN)
The present invention relates to a catalyst system for producing ethylene copolymers in a high temperature solution process, the catalyst system comprising (i) a metallocene complex of a group 4 transition metal comprising at least one ligand selected from optionally substituted cyclopentadienyl (Cp), indenyl (Ind) and fluorenyl (Flu) ligands and (ii) a solid alkyl aluminium oxide cocatalyst The invention relates also to the preparation of the catalyst system, use thereof in the high temperature solution process and to a process comprising polymerizing ethylene and a C4-10 alpha-olefin comonomer in a high temperature solution process in the presence of the catalyst system.
(FR)
La présente invention concerne un système catalytique pour produire des copolymères d'éthylène dans un procédé de solution à haute température, le système catalytique comprenant (i) un complexe métallocène d'un métal de transition du groupe 4 comprenant au moins un ligand choisi parmi les ligands cyclopentadiényle (Cp), indényle (Ind) et fluorényle (grippe) éventuellement substitués et (ii) un cocatalyseur d'oxyde d'aluminium alkyle solide. L'invention concerne également la préparation du système catalytique, l’utilisation de celui-ci dans le procédé de solution à haute température et un procédé comprenant la polymérisation de l'éthylène et d'un comonomère d'alpha-oléfine en C4-10 dans un procédé de solution à haute température en présence du système catalytique.
