Title:
CYCLIC OLEFIN POLYMER, CYCLIC OLEFIN POLYMER COMPOSITION, AND MOLDED OBJECT
Document Type and Number:
WIPO Patent Application WO/2023/276873
Kind Code:
A1
Abstract:
This cyclic olefin polymer, which has a norbornene skeleton, is a cyclic olefin copolymer or cyclic olefin ring opening polymer, and satisfies requirement (a) below. (Requirement (a)) The cyclic olefin polymer is composed of a chain olefin structural unit (A) and a structural unit (B) containing a cyclic olefin having a norbornene skeleton. The presence ratio between a meso structure and a racemo structure (racemo structure/meso structure) in a chain of the structural unit (B) - the structural unit (A) - the structural unit (B) measured by 13C-NMR is 0.01 to 100.
