Title:
CYCLIC OLEFIN COPOLYMER AND CYCLIC OLEFIN COPOLYMER FILM
Document Type and Number:
Japanese Patent JP2014224170
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a cyclic olefin copolymer resin film which sufficiently suppresses phase difference in an in-plane or thickness direction to a low level and suppresses generation of wrinkles.SOLUTION: A cyclic olefin copolymer composition is provided, including an ethylene unit and a norbornene unit. The norbornene unit includes dyad moieties; and stereoregularity of the dyad moieties is a meso form and a racemo form, with a ratio of (meso form dyad)/(racemo form dyad) being less than 2.0. The cyclic olefin copolymer composition has a glass transition temperature of 140 to 210°C.
