Abstract
Disclosed herein are catalyst compositions containing boron bridged, cyclopentadienyl-indenyl metallocene compounds with an alkenyl substituent. These catalyst compositions can be used for the polymerization of olefins. For example, ethylene homopolymers produced using these catalyst compositions can be characterized by a density less than 0.97 g/cmand a melt index greater than 50 g/10 min.
