A very effective catalyst system for olefin polymerization consists of a cocatalyst, preferably an aluminoxane, and a metallocene of the formula (I) [Figure] (I) in which, preferably, M1 is Zr, R1 and R2 are alkyl or halogen, R3 to R6 are alkyl, －(CR8R9)m－R7－(CR8R9)n－is a chain having one or more me
A very effective catalyst system for olefin polymerization consists of a cocatalyst, preferably an aluminoxane, and a metallocene of the formula (I) [Figure] (I) in which, preferably, M1 is Zr, R1 and R2 are alkyl or halogen, R3 to R6 are alkyl, －(CR8R9)m－R7－(CR8R9)n－is a chain having one or more members, in which R7 can also be a (substituted) hetero atom, and m+n is zero or 1. The catalyst system leads to polymers of variable molecular weight and stereotacticity, depending on the substituents R3 to R6 chosen, at polymerization temperatures which are relevant in industry.
