Abstract
A catalyst for the ring-opening copolymerization of a hexachlorocyclopentadiene-1,5-cyclooctadiene adduct and a cycloolefin, other than cyclohexene, having 4 to 12 carbon atoms and containing at least one non-conjugated vinylene double bond. Owing to modification by oxy bidentate-type ligands, the chlorotungsten catalyst system affords a more favorable comonomer reactivity ratio and is thus utilized.
