Abstract: Metallocene compounds of formula (I) are new. In (I), Cp = optionally substituted cyclopentadienyl; Ind = optionally substituted indenyl; M = tetravalent metal; R -R = H or 1-20C hydrocarbyl; m = 1 or 2; k, l = 1 if m = 1; k, l = 0 if m = 2. Also claimed are (i) catalysts (I-A) containing compound(s) (I) and cocatalyst(s), (ii) a process for the production of polyolefins by polymerisation of olefins in presence of these catalysts, (iii) polyolefins obtained by this process, (iv) moulded products containing these polyolefins, and (v) a process for the production of (I) by reacting compounds of formula (II) with compounds of formula M(NR 2NR 2NR3 NR 2) (III). The preferred cocatalyst is an aluminium and/or boron compound. The catalyst may also contain a support, and metallocene (I) may be prepolymerised.

Abstract: The present invention relates to a process for the preparation of a polyolefin by polymerisation of at least one olefin in the presence of a stereorigid metallocene compound containing, as ligands, at least two substituted or unsubstituted cyclopentadienyl groups 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.

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 material of a cycloolefin copolymer has a structure of alternating cycloolefin sequences, and has crystallinity in a temperature range from 210 to 320.degree.C. The cycloolefin is prepared by polymerization of at least one polycyclic olefin, monocyclic and/or acyclic olefin with an open-chain olefin using a catalyst of a metallocene and an aluminoxane.

Abstract: As starting materials for substrates for optical storage disks, cycloolefin copolymers (COC) are produced by a polymerization process in which the polymerization is terminated at a point in time at which the molar-mass distribution M w/M n is 15,000 g/mol and M w/M n less than/equal to 4 and greater than/equal to 2. The substrate is produced by thermal deformation either of a single COC having a molar-mass distribution M w/M n of
