Title:
CYCLIC OLEFIN RING-OPENED POLYMER HYDRIDE, RESIN MOLDED ARTICLE, AND OPTICAL MEMBER
Document Type and Number:
WIPO Patent Application WO/2016/052302
Kind Code:
A1
Abstract:
　The present invention is: a cyclic olefin ring-opened polymer hydride comprising tetracyclododecene-derived repeating units and other repeating units derived from a norbornene-based monomer, the cyclic olefin ring-opened polymer hydride characterized in that the glass transition temperature, the melt flow rate, and the bending strength of a resin molded article obtained using the cyclic olefin ring-opened polymer hydride are in specific ranges; a resin molded article obtained using the cyclic olefin ring-opened polymer hydride; and an optical member comprising the resin molded article. The present invention provides a cyclic olefin ring-opened polymer hydride having excellent thermal yellowing resistance, dimensional stability at high temperature, and molding properties, a resin molded article obtained using the cyclic olefin ring-opened polymer hydride, and an optical member comprising the resin molded article.
