A highly effective catalyst system for the polymerisation of olefins comprises a cocatalyst, preferably an aluminoxane, and a metallocene of the formula (I) in which, preferably, M is Zr, R and R are an alkyl or halogen, R to R are alkyl, -(CRR)m-R-(CRR)n- is a single- or multi-membered chain in which R may also be a (substituted) heteroatom, and m + n is zero or 1. The catalyst system gives polymers of variable molecular weight and stereotacticity, depending on the selected substituents R to R, at industrially relevant polymerisation temperatures.
