RIGID CYCLOOLEFIN COPOLYMER FILM |
| 摘要 |
A rigid single- or multilayer non-oriented or monoor biaxially oriented film in which at least one layer comprises a cycloolefin copolymer, wherein the cycloolefin copolymer has an intrinsic E modulus (Ei) which has the following dependence on the glass transition temperature Tg: Ei = (0.0025 ¢GPa/.degree.C! x Tg ¢.degree.C!) + B ¢Gpa! where B - 2.93-3.19 and Tg is the glass transition temperature.
