Abstract

A cycloolefin resin composition which controls the flexibility of a cycloolefin resin and may be molded in an environment having a temperature exceeding about 140° C. is provided. A cycloolefin resin film, a cycloolefin resin preform and the like are provided utilizing the cycloolefin resin composition including two or more cycloolefin copolymer resins having Tg values different from each other by about 10° C. or more, and the storage modulus of about 120° C. (E') relative to the storage modulus of about 50° C. (E′), namely E′/E′is set within the range of about 0.15 to about 0.65.
