Abstract

The invention relates to a method for producing a cycloolefin copolymer by polymerization of 0.1-99.9 wt. %, with respect to the total amount of monomers, of at least one polycyclic olefin, 0-99.9 wt. %, with respect to the total amount of monomers, of at least one monocyclic olefin, 0.1-99.9 wt. %, with respect to the total amount of monomers, of at least one acyclic 1-olefin, in the presence of a catalyst system consisting of at least one cocatalyst and at least one metal coordination complex with taut geometry.
