The present invention relates to cycloolefin copolymer having a solution viscosity (eta) > 0.25 dl/g (measured in accordance with DIN 53 728 in decalin at 135°C), comprising polymerized units (A) of at least one cyclic olefin and (B) if desired, one or more acyclic olefins, wherein (C) polymerized units are included which comprise at least one functionalized structural unit which a) is derived from a cyclic olefin and contains at least one heteroatom attached directly to a ring atom of the cyclic olefin, or b) is derived from a cyclic or acyclic olefin and contains at least one group of atoms containing two heteroatoms both attached to the same carbon atom, or c) is derived from a cyclic or acyclic olefin and contains at least one aldehyde group, or d) is derived from a cyclic or acyclic olefin and contains at least one group of atoms in which a nitrogen atom is attached via a double bond to a carbon atom, and where, in the case that the functionalized structural unit is derived from a cyclic olefin, exactly two mutually adjacent carbon atoms of this functionalized cyclic structural unit are incorporated into the principal polymer chain. The cycloolefin copolymer is suitable for use as a coating material or adhesion promoter.
