Abstract

Process for the preparation of a high molecular weight olefin polymer A very active catalyst system for olefin polymerization is composed of an aluminoxane and a metallocene of the formula I

(see formula I) wherein preferably M1 is Zr or Hf, R1 and R2 are alkyl or halogen, R3 and R4 are hydrogen, R5 and R6 are alkyl or haloalkyl, -(CR8R9)m-R7-(CR8R9)n- is a single-membered or multimembered chain in which R7 may also be a (sub-stituted) hetero atom, and m+n is zero or 1. The catal-yst system gives polymers having a high molecular weight and high stereospecificity.
