Abstract
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 its use in a polymerization process to produce olefin polymers having an unexpected improvement in processability.
