Title:
CYCLOOLEFIN COPOLYMER, RESIN COMPOSITION, AND FILM- OR SHEET-SHAPED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2023/120669
Kind Code:
A1
Abstract:
A cycloolefin copolymer comprising constituent units derived from a norbornene monomer and constituent units derived from ethylene, wherein the constituent units derived from a norbornene monomer comprise meso diads and racemo diads and triads, the ratio of the content (mol%) of the meso diads to the content (mol%) of the racemo diads being 0.10-3.00 and the content of the triads being 2.5 mol% or less; a resin composition including the cycloolefin copolymer; and a film- or sheet-shaped article obtained by shaping the cycloolefin copolymer or the resin composition.
