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°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. (see formula I, II, III, IV)
