Polymers of polycyclic olefins of the formulae I to IV having a viscosity number greater than 20 cm.sup.3 /g and a glass transition temperature above 100.degree. 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. ##STR1##
