    Abstract: HOE 92/F 018 of the disclosure Catalyst and process for the polymerization and copolymerization of olefins A highly effective catalyst system for the polymerization or copolymerization of olefins comprises at least one metallocene as transition-metal compound and at least one aluminum compound of the formula II (II) and/or of the formula (III) (III) where, in the formulae (II) and (III), the radicals R14 may be identical or different and are an alkyl group, an aryl group, benzyl or hydrogen, and p is an integer from 2 to 50, and at least one aluminum compound of the formula IV (IV) where R15, R16 and R17 are identical or different and are a hydrogen atom, an alkyl group, an alkylsilyl group, an alkoxy group, an aryl group, an aryloxy group, an alkenyl group, an arylalkyl group, an alkylaryl group, an arylalkenyl group, a halogen atom or a radical of the formula -OSiR15R16R17 where R15, R16 and R17 are as defined in the description.

    Abstract: Catalysts consisting of a metallocene of formula (I) and a cocatalyst are claimed, M = a Group IVb, Vb or VIb metal; R , R = H, 1-10C alkyl or alkoxy, 6-10C aryl or aryloxy, 2-10C alkenyl, 7-40C aralkyl or alkaryl, 8-40C aralkenyl, OH or halogen; R = H, halogen, optionally halogenated 1-10C alkyl, 6-10C aryl, N(R )2, SR , OSi(R )3, Si(R )3 or P(R )2 (with R = halogen, 1-10C alkyl or 6-10C aryl); R -R = as for R , or adjacent groups may form part of one or more aromatic or aliphatic rings, or the groups R and R or R may form such rings with the attached atoms; R = -X-, -X-X-, -Y-Y-, -O-X-O- -Y-, -O-X-, -Y-X-, -Y-Y-Y-, =BR , =AlR , -O-, -S-, =SO, =SO2, =NR , =CO, =PR or =P(O)R ; X = -M R R -; Y = -CR R ; R , R = H, halogen, 1-10C alkyl, fluoroalkyl or alkoxy, 6-10C aryl, fluoroaryl or aryloxy, 2-10C alkenyl, 7-40C aralkyl or alkaryl, or 8-40C aralkenyl, or R + R + the attached atoms may form ring(s); M = silicon, germanium or tin. Also claimed are: (i) polyolefins obtained by (co)polymerisation of olefins of formula Ra-CH=CH-Rb (with Ra, Rb = H or 1-14C hydrocarbyl, or Ra + Rb may form part of one or more rings) at -60 to 200 degrees C and 0.5-100 bar in solution, suspension or gas phase, in presence of these catalysts; (ii) a process for the production of metallocenes (I); and (iii) intermediate indanones, indenes and bridged ligand systems formed in this process.
