The present techniques relate to catalyst compositions, methods, and polymers encompassing a Group 4 metallocene compound comprising bridged 5-cyclopentadienyl-type ligands, typically in combination with a cocatalyst, and a activator. The bridged 5-cyclopentadienyl-type ligands are connected by a cyclic substituent. The catalysts of the present techniques may be more effective at the incorporation of comonomers into the backbone of a polyolefin polymer. |
