Abstract: Bridged catalyst component in which a bridge spans two cylcopentadienyl or aromatic groups. The Cp or aromatic groups are attached to the same or different heteroatoms of the bridge, which heteroatoms are also bonded to a metal. A catalyst system can be made by contacting the bridged component with a cocatalyst. Polymerization of olefins can be catalyzed by the system.
