The present invention relates to a cycloolefin copolymer having a solution viscosity (eta) < 0.25 dl/g (measured in accordance with DIN 53728 in decalin at 135°C), which comprises polymerized units (A) of at least one cyclic olefin and (B), if desired, of one or more acyclic olefins, wherein (C) polymerized units are present which contain at least one functionalized structural unit which a) is derived from a cyclic olefin and contains at least one heteroatom which is 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 ofatoms which has two heteroatoms both of which are attached to the same carbon atom, or c) is derived from a cyclic or acyclic olefin and contains at least one aldehydegroup, or d) is derived from a cyclic or acyclic olefin and contains at least one group ofatoms in which a nitrogen atom is attached via a double bond to a carbon atom, and, where the functionalized structural unit is derived from a cyclic olefin, exactly two adjacent carbon atoms of this functionalized cyclic structural unit are incorporated into the polymer main chain. The cycloolefin copolymer is suitable as coating material or as adhesion promoter.
