A very active catalyst system for olefin polymerization is composed of an aluminoxane and a metallocene of the formula I ##STR1## wherein preferably M.sup.1 is Zr or Hf, R.sup.1 and R.sup.2 are alkyl or halogen, R.sup.3 and R.sup.4 are hydrogen, R.sup.5 and R.sup.6 are alkyl or haloalkyl, --(CR.sup.8 R.sup.9).sub.m --R.sup.7 --(CR.sup.8 R.sup.9).sub.m --is a single-membered or multimembered chain in which R.sup.7 may also be a (substituted) hetero atom, and m+n is zero or 1. The catalyst system gives polymers having a high molecular weight and high stereospecificity.
