Also claimed are COC polymers obtd. by this process, esp. with a content of more than 40 mole% norbornene units. Also claimed are extruded parts, injection moulded prods. and polymer alloys contg. the above COC polymer(s).

Abstract: Polymers of polycyclic olefins, such as, for example, norbornene or tetracyclododecene, or copolymers of polycyclic olefins with cycloolefins and/or 1-olefins, having a very narrow molecular weight distribution are obtained without ring opening by polymerisation in which a catalyst is used which comprises an aluminoxane and a stereorigid, chiral metallocene compound of an element from group IVb to VIb, and in which the reaction is terminated at the point when the molecular weight distribution Mw/Mn of the resultant polymer is
