Abstract: The present invention relates to a process for the preparation of a polyolefin by polymerization of at least one olefin in the presence of a stereorigid metallocene compound containg, as ligands, at least two substituted or unsubstituted cyclopentadienyl groups bonded to one another via monocyclic or polycyclic ring system, in which at least one cyclopentadienyl group is fused to the monocyclic or polycyclic ring system.

Abstract: Polymers of polycyclic olefins such as, for example, norbornene or tetracyclododecene, or copolymers of polycyclic olefins with cycloolefins and/or 1-olefins are obtained without ring opening, in high space-time yield, with high cycloolefin incorporation rate and at industrially favourable polymerisation temperatures by a bulk polymerisation in which the catalyst used consists of an aluminoxane and of a stereorigid, chiral metallocene compound of an element of groups IVb to VIb, where the hydrocarbon radicals forming the sandwich structure are different.

Abstract: HOE 92/F 045 : Cycloolefin block copolymers and a process for their preparation Cycloolefin block copolymers, which in particular are suitable as phase promoters, are preferably obtained by copolymerization of polycyclic olefins, such as norbornene, with acyclic olefins, such as ethylene, by, at a molecular weight distribution Mw/Mn of the polymer block forming of less than 2, changing the reaction conditions one or more times in such a way that the monomer/comonomer ratio changes by at least 10 % or a further polymerizable monomer is metered into the monomer or the monomers.
