Abstract: Cycloolefin polymers having a high viscosity number are obtained by polymerization of a polycyclic olefin and, if desired, an acyclic olefin and/or a monocyclic olefin in the presence of a catalyst system which comprises an aluminoxane and a metallocene compound of the formula ##STR1## in which R.sup.16 is fluorenyl or indenyl and R.sup.17 is cyclopentadienyl and the bridge R.sup.18 contains silicon.
