Patent

CA 2329438

The present invention relates to a mixed catalyst system of at least one bridged, bulky ligand metallocene-type compound, and at least one bridged, asymmetrically substituted, bulky ligand metallocene-type compound, a method of making the mixed catalyst system and to their use in a polymerization process to produce polymers having an unexpected improvement in processability.

La présente invention concerne un système de catalyseurs mélangés d'au moins un composant de type métallocène ligand gonflant en pont, et d'au moins un composant de type métallocène ligand gonflant en pont à substitution asymétrique. L'invention concerne également un procédé de réalisation d'un tel système de catalyseurs mélangés et leur utilisation dans un processus de polymérisation de façon à produire des polymères présentant une amélioration inattendue de l'aptitude au traitement.
