(57) [Summary] [Purpose] To obtain a PTP or blister pack packaging sheet or film which is excellent in moisture resistance and transparency and is also excellent in vacuum or compressed air moldability. A copolymer of a cyclic olefin and ethylene represented by the following formula, having an intrinsic viscosity of 0.01 to 10 dl / g and a softening temperature of 50 as measured in decalin at 135 ° C. PTP consisting of amorphous polyolefin at ~ 200 ° C Or blister pack packaging sheet or film. [Chemical 1] (N is 0 or 1, m is 0 or a positive integer, q is 0 or 1, R 1 to R 18 , R a and R b are groups selected from H, halogen and hydrocarbon groups. R 15 to R 18 May combine with each other to form a monocyclic ring or a polycyclic ring, and the ring may have a double bond.R 15 and R 16 or R 17 and R 18 form an alkylidene group. You may.) |
