Abstract:
Disclosed herein are catalyst compositions containing boron-bridged, cyclopentadienyl-fluorenyl 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 combination of a flat or a conventional comonomer distribution and low levels of long chain branching.
