Abstract

PURPOSE: To obtain the titled copolymer useful as an optical material, having improved transparency, heat resistance, chemical resistance, uniformity, etc., high bulk density and good handleability in molding, by copolymerizing ethylene with a specific cyclic olefin in the presence of a specific catalyst.
CONSTITUTION: Ethylene is copolymerized with one or more cyclic olefins (e.g., compound shown by formula III, formula IV, etc.) selected from a group consisting of unsaturated monomers shown by formulas I and II (n and m are positive integer; l≥3; R1WR10 are H, halogen or hydrocarbon) in the presence of a catalyst consisting of a soluble vanadium compound (e.g., VOCl3, etc.) and an organoaluminum compound (e.g. triethylaluminum, etc.) in a liquid phase of a hydrocarbon medium (e.g. hexane, benzene, toluene, etc.) to form a solution of a cyclic olefinic random copolymer, a ketone or a alcohol is brought into contact with the solution, the copolymer is precipitated, separated and brought into contact with a ketone.
