CA 2253804

A catalysis system containing an olefin polymerization catalyst having at least one Group 3 to Group 10 transition metal or one of the Lanthanide series of the Periodic Table and an organic support is homogeneous and has particular applicability in the producttion of polyolefins having narrow molecular weight distribution. The support of the catalysis system is the reaction product of a silicone and a polyamine. The catalysis system has high thermal stability.

Cette invention concerne un système de catalyse contenant un catalyseur de polymérisation d'oléfine comprenant au moins un métal de transition issu des groupes 3 à 10 ou une des lanthanides du tableau périodique des éléments et un support organique. Ce système de catalyse est homogène et s'applique tout particulièrement à la production de polyoléfines ayant une distribution étroite des masses molaires. Le support du système de catalyse est le produit de réaction d'une silicone et d'une polyamine. Ledit système de catalyse se caractérise par une stabilité élevée à la chaleur.
