CROSSLINKED PRODUCT OF CYCLIC OLEFIN RESIN, AND PROCESS FOR PRODUCING SAME |
摘要 |
A chain olefin-cyclic olefin copolymer is irradiated with an electron beam for crosslinking to prepare a crosslinkedproduct of a cyclic olefinic polymer. The cyclic olefin contains a bicyclic olefin. The proportion of the cyclic olefin in the total amount of the chain olefin and the cyclic olefin is more than 15% by mol and not more than 40% by mol. The chain olefin-cyclic olefin copolymer has a glass transition temperature of 20 to 80°C or has a degree of crystallinity of not more than 1%. The crosslinked product may have a haze of not more than 2%. The crosslinked product of the present invention has a low haze and a high transparency and combines heat resistance and flexibility. |
