ABSTRACT:
A process for the preparation of cyclopentadiene copolymers, wherein cyclopentadiene, dicyclopentadiene, tricyclopentadiene, their C.sub.1 -C.sub.3 -alkyl derivatives or co-dimers of cyclopentadiene with a diene of 4 or 5 carbon atoms are reacted with acetylenically unsaturated compounds, with or without other copolymerizable olefinically unsaturated monomers, at from 200.degree. to 320.degree. C. The cyclopentadiene polymers prepared according to the invention may be used, for example, as resin additives for surface coatings, tackifiers in adhesives or resins for printing inks.
