CA 2428855

A polymerization catalyst system and a method for preparing the catalyst system is disclosed. The catalyst system includes a bulky ligand metallocene catalyst compound, preferably containing a single cyclopentadienyl or substituted cyclopentadienyl-type ring system, a Group 13 element containing first modifier, and a cycloalkadiene second modifier. The present invention also provides a process for polymerizing olefins(s) utilizing the catalyst systems described herein.

L'invention porte sur un système catalyseur de polymérisation et sur son procédé de préparation. Le système catalyseur comprend un composé catalyseur gonflant de métallocènes de ligand contenant de préférence un système de noyau de type cyclopentadiényle unique or cyclopentadiényle substitué, un premier modificateur contenant un élément du groupe 13 et un second modificateur de cycloalcadiène. Cette invention porte également sur un procédé de polymérisation d'oléfine(s) utilisant les systèmes catalyseurs précités.
