Abstract

The invention relates to a process for the preparation of a heterogeneous metallocene catalyst component from a suitably substituted metallocene of the sub-group 4 of the Periodic Table of the Elements and from poly(methylhydrogensiloxane) under the concomitant action of a catalyst. The metallocene component and a suitable aluminoxane can be used as catalyst for the polymerization of 1-olefins, cyclic olefins, diolefins and cyclic diolefins.
