Title:
CYCLIC OLEFIN COPOLYMER, AND METHOD FOR MANUFACTURING CYCLIC OLEFIN COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2023/149505
Kind Code:
A1
Abstract:
To provide: a cyclic olefin copolymer, being a copolymer of a cyclic olefin monomer and α-olefin having a carbon number of 3 to 20, with outstanding tensile strength and fracture strain; and a method for manufacturing the cyclic olefin copolymer which can favorably manufacture said cyclic olefin copolymer. The copolymer of a cyclic olefin monomer and α-olefin having a carbon number of 3 to 20, wherein the amount of α-olefin-derived structural units is 10 mol% to 50 mol% with respect to the total structural units, and a value in which the half value width of the primary peak is divided by a value q of the peak top is in the range of 0.15 to 0.45 on a primary scattering curve for a scattering vector q in small-angle X-ray scattering in the cyclic olefin copolymer.
