Abstract

The present invention relates to a process for the preparation of a polyolefin by polymerization of at least one olefin in the presence of a stereorigid metallocene compound containing, as ligands, at least two substituted or unsubstituted cyclopentadienyl groups bonded to one another via a monocyclic or polycyclic ring system, in which at least one cyclopentadienyl group is fused to the monocyclic or polycyclic ring system.
