Abstract:
The present techniques relate to catalyst compositions, methods, and polymers encompassing a Group 4 metallocene compound comprising bridged η5-cyclopentadienyl-type ligands, typically in combination with a cocatalyst, and an activator. The bridged η5-cyclopentadienyl-type ligands are connected by a cyclic substituent.
