Abstract:
Disclosed herein are catalyst compositions containing boron bridged, bis-indenyl metallocene compounds with an alkenyl substituent. These catalyst compositions can be used for the polymerization of olefins. For example, ethylene copolymers produced using these catalyst compositions can be characterized by a density less than 0.92 g/cm3 and a melt index greater than 25 g/10 min.
