ABSTRACT:
Method of producing a copolymer of cyclopentene comprising the steps of preliminarily mixing in an inert solvent a polycyclic olefin having at least one double bond in a ring, with a metallic compound containing tungsten or molybdenum as a catalyst, to form a complex compound with each other; polymerizing cyclopentene in an inert solvent in the presence of a catalyst system comprising a metallic compound of tungsten or molybdenum and an organo metallic compound of Group I-IV of the Periodic Table, and then adding the complex compound to the polymerizing cyclopentene system, thereby to produce a novel copolymer of cyclopentene.
