Metallocenes with a 4-(eta5-3'-alkyl-cyclopentadienyl)-4,6,6-trimethyl- -(eta5-2-alkyl-4,5-tetrahydropentalene) ligand system are excluded. Also claimed are catalyst components contg. supported and/or prepolymerised (I); the prodn. of a cycloolefin copolymer (II) in the presence of a catalyst contg. cpd(s). (I) and cocatalyst(s) (III); (II) pe se; polymer alloys contg. (II); mouldings contg. (II) or the polymer alloy; and the use of (I) in the prodn. of (II). |
