摘要

INVENTION: PROCESS FOR THE PREPARATION OF COPOLYMERS OF CYCLOPENTENE WITH UNSATURATED ALICYCLIC COMPOUNDS INVENTORS: Eilert A. Ofstead and Ken W. Donbar There is disclosed a process for the preparation of polymers of cyclopentene or copolymers of cyclopentene with non-conjugated unsaturated alicyclic compounds containing at least 7 carbon atoms in the ring and at least one double bond in the ring or polycyclic olefins or non-conjugated diolefins by the use of -the catalyst system comprising (a) -tungsten halides or oxyhalides, (b) an organoaluminum compound, (c) an alcohol, and (d) a halogenated phenol.
