Patent

CA 2730726

The present invention provides polymerization catalyst compositions employing half-metallocene compounds with a heteroatom-containing ligand bound to the transition metal. Methods for making these hybrid metallocene compounds and for using such compounds in catalyst compositions for the polymerization and copolymerization of olefins are also provided.

La présente invention concerne des compositions de catalyseur de polymérisation utilisant des composés hémi-métallocènes avec un ligand contenant un hétéroatome lié au métal de transition. La présente invention concerne en outre des procédés pour préparer ces composés métallocènes hybrides et pour utiliser de tels composés dans des compositions de catalyseur pour la polymérisation et la copolymérisation doléfines.
