05990254 is referenced by 29 patents and cites 39 patents.

The present invention relates to a stereorigid metallocene compound containing, as ligands, at least two substituted or unsubstituted cyclopentadienyl groups which are bonded to one another via a monocyclic or polycyclic ring system, where at least one cyclopentadienyl group is fused to the monocyclic or polycyclic ring system, and to a process for the preparation of a cycloolefin copolymer. The cycloolefin copolymers obtained in this way have high tear strengths and are suitable for the production of extrusion parts and injection moldings.
