THERMOPLASTIC RESIN COMPOSITION, OPTICAL FILM AND RETARDATION FILM

摘要

A thermoplastic resin composition and an optical film, which each comprises a cycloolefin polymer (A) and a vinyl polymer (B) comprising structural units derived from p-isopropenyl-phenol. The composition and the optical film exhibit excellent compatibility in spite of their keeping the low birefringence inherent in the thermoplastic resin composition comprising the polymers (A) and (B), and are excellent in weather resistance and thermal resistance.
