Abstract: Polymers of polycyclic olefins, such as, for example, norbornene or tetracyclododecene, or copolymers of polycyclic olefins with cycloolefins and/or 1-olefins, having a very narrow molecular weight distribution are obtained without ring opening by polymerisation in which a catalyst is used which comprises an aluminoxane and a stereorigid, chiral metallocene compound of an element from group IVb to VIb, and in which the reaction is terminated at the point when the molecular weight distribution Mw/Mn of the resultant polymer is

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: Cycloolefin block copolymers which are particularly suitable as phase promoters are preferably obtained by copolymerisation of polycyclic olefins, such as norbornene, with acyclic olefins, such as ethylene, by modifying the reaction conditions once or more than once, at a molecular weight distribution Mw/Mn of less than 2 of the polymer block forming, in such a way that the monomer/comonomer ratio changes by at least 10% or a further polymerisable monomer is metered into the monomer or monomers.

Abstract: polymerization catalysts. SUBSTANCE: catalyst represents sterilely rigid metallocene compound containing at least two optionally substituted cyclopentadienyl groups as ligands linked to each other through monocyclic annular system, one of cyclopentadienyl groups being annelated to monocyclic system and this ligand system being different from 4-(η5-3-alkylcyclopentadienyl)-4,6,6-trimethyl-(η5-2- alkyl-4,5-tetrahydropentalene) group and defined by formula I: , wherein M is IVb group metal; R1 and R2, identical or different, are halogen atoms, C1-C10-alkyls, or NR123, group with R13 being C1-C10-alkyl; R3,R4,R5,R6,R7,R8 and R9, identical or different, are hydrogen atoms, C1-C10-alkyls, or group -R13-SiR133-, with R13 being as indicated above; R10 is C1-C20-alkyl; R11 and R12, identical or different, are C1-C20-alkyl, C6-C20-aryl, or C2-C12-alkenyl; and n is integer from 1 to 10. Catalyst is applicable in production of polyolefins via polymerization of at least one cycloolefin. EFFECT: enabled production of olefin homopolymers and copolymers with improved physico-chemical properties, especially those with reduced crystallinity, increased impact resistance, elevated transparency, high flowability at processing temperatures, low molecular weight, and reduced melting temperature. 8 cl, 3 tbl, 33 ex
