Title:
NORBORNENE-BASED ADDITION COPOLYMER, PROCESS FOR PRODUCING ADDITION COPOLYMER AND ITS USE
Document Type and Number:
Japanese Patent JP2007197603
Kind Code:
A
Abstract:
To provide a norbornene-based addition copolymer having excellent heat resistance, being excellent in transparency and toughness, melt-moldable and suitably used as an optical material; a process for producing the addition copolymer; and a film or sheet prepared by molding the addition copolymer.
The norbornene-based addition copolymer of the invention has a structural unit derived from bicyclo[2.2.1]hepta-2-ene and a structural unit derived from bicyclo[2.2.1]hepta-2-ene having a ≥6C alkyl substituent at a specific proportion. In a wide angle X-ray scattering (WAXS) pattern for the addition copolymer, 2θ of a lower angle peak of the measured two peaks is 10° or greater.
