Abstract: The present invention relates to a sterically rigid metallocene compound which, as ligands, contains at least two substituted or unsubstituted cyclopentadienyl groups which are bonded to one another via a mono- or polycyclic ring system, at least one cyclopentadienyl group being fused to the mono- or polycyclic ring system, and to a process for the preparation of a cycloolefin copolymer. The cycloolefin copolymers thus obtained have high tensile strengths and are suitable for the production of extruded parts and injection-moulded articles.

Abstract: A very effective catalyst system for the polymerization or copolymerization of olefins comprises a cocatalyst, preferably an aluminoxane or a supported aluminoxane, and a metallocene of the formula I (see formula I) in which, in the preferred form, M1 is Zr or Hf, R1 and R2 are halogen or alkyl, R3 is alkyl, R4 to R12 are alkyl or hydrogen and R13 is a (substituted) alkylene or heteroatom bridge. The metallocenes, in particular the zirconocenes, produce polymers of very high molecular weight, in the case of prochiral monomers polymers of very high molecular weight, very high stereotacticity and very high melting point, at high catalyst activities in the industrially particularly interesting temperature range between 50 and 80.degree.C. In addition, reactor deposits are avoided by means of supported catalyst systems.
