ABSTRACT:
Cycloolefin random copolymer compositions which contain a blend of at least two or three cycloolefin random copolymers are disclosed. The random copolymers are obtained by copolymerization of ethylene and at least one of two cycloolefins. The resin compositions exhibit excellent moldability and transparency, heat resistance, thermal aging resistance, chemical resistance, solvent resistance, dielectric and mechanical characteristics and transferability of the pit.
