Polymers of polycyclic olefins of the formulae I to IV having a viscosity number greater than 20 cm3/g and a glass transition temperature above 100 DEG C. are obtained without ring opening at a high polymerization rate and at polymerization temperatures advantageous from the technical point of view by means of a catalyst which is composed of a stereo-rigid, chiral metallocene compound of groups IVb to VIb of the Periodic Table of the Elements and an aluminoxane. <IMAGE> (I) <IMAGE> (II) <IMAGE> (III) <IMAGE> (IV) |
