Abstract
Abstract Chemically homogeneous cycloolefin copolymers of polycyclic olefins, for example norbornene or tetracyclododecene, with cycloolefins and/or acyclic olefins are obtained without ring opening and in high space-time yields if a catalyst system is used which comprises an aluminoxane and a stereorigid metallocene compound of an element from groups IVb to VIb, of the formula <IMAGE> the part of the metallocene molecule formed by M<1> and the substituents R<16>-R<17> having C1 symmetry or being in the meso form.
