ABSTRACT:
This invention relates to catalyst compositions, methods, and polymers encompassing a Group 4 metallocene with bridging η5-cyclopentadienyl-type ligands, in combination with a cocatalyst and an activator-support. The compositions and methods disclosed herein provide ethylene polymers with low levels of long chain branching.
