Being the building a bridge body of annular olefin resin and the building a bridge body

摘要

To prepare a crosslinked product of the cyclic olefin resin can be crosslinked with an electron beam and a cyclic olefin copolymer - linear olefin. The cyclic olefins include bicyclic olefins. Ratio of the cyclic olefin is 40 mol% or less and more than 15 mol% based on the total of the cyclic olefin and a linear olefin. The linear olefins - a glass transition temperature of the cyclic olefin copolymer is either 20~80 ℃, crystallinity of 1% or less. Haze may be less than 2% this cross-linked product. While retaining a high degree of transparency with low haze, crosslinked product of the present invention can achieve both flexibility and heat resistance.
