Title:
RING-OPENED COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2019/208239
Kind Code:
A1
Abstract:
A ring-opened copolymer which contains a structural unit derived from a norbornene compound having a specific structure and a structural unit derived from a monocyclic olefin, and which is configured such that: the content ratio of the structural unit derived from a norbornene compound to all repeating structural units in the ring-opened copolymer is 25-90% by weight; the content ratio of the structural unit derived from a monocyclic olefin to all repeating structural units in the ring-opened copolymer is 10-75% by weight; the weight average molecular weight of the ring-opened copolymer is from 100,000 to 1,000,000; and the cis/trans ratio in the ring-opened copolymer is from 0/100 to 50/50.
