PURPOSE: To provide a composite polymer sheet which consists of a crystalline polymer and a hydrogenated ring-opening dicyclopentadiene polymer having a specified glass transition temperature and is excellent in transparency, stretchability, moldability, heat resistance, etc. n CONSTITUTION: A composite polymer sheet which consists of a crystalline polymer (e.g. PP) and a hydrogenated ring-opening dicyclopentadiene polymer having a glass transition temperature of 100°C or higher (e.g. a hydrogenated ring- opening dicyclopentadiene-norbornene copolymer). n COPYRIGHT: (C)1992,JPO&Japio |
