Patent ID: 8114942

Claim:
A cycloolefin resin composition (C) comprising: a cycloolefin polymer consisting of one or two or more kinds of the structures represented by the general formula (5): wherein R 4 is a di-valent group represented by general formula (6): wherein p is an integer of 0 to 2, and a plurality of R 4 's, if any, may be the same or different from each other, R 5 is a hydrogen atom or a mono-valent group selected from the group consisting of a hydrocarbon group having 1 to 5 carbon atoms, and a plurality of R 5 's, if any, may be the same as or different from each other, and x and y each represents a copolymerization ratio, and are each a real number satisfying 5/95≦y/x≦95/5, with x and y being presented on a molar basis, and a saturated hydrocarbon compound having a boiling point of 50° C. or higher wherein said resin composition (C) comprises 0.01 to 10 parts by weight of said saturated hydrocarbon compound having a boiling point of 50° C. or higher, per 100 parts by weight of said cycloolefin polymer, and wherein said saturated hydrocarbon compound having a boiling point of 50° C. or higher is a hydrogenation product of a monomer employed in the production of said cycloolefin polymer.
