Title:
SOLUTION COMPOSITION AND FILM
Document Type and Number:
Japanese Patent JP2023112593
Kind Code:
A
Abstract:
To provide a solution composition comprising a cyclic olefin copolymer which is a copolymer of a cyclic olefin monomer and an α-olefin having 3 or more and 20 or less carbon atoms and can form a film having both excellent breaking strain and toughness and having excellent bending resistance and to provide a film formed using the solution composition.SOLUTION: There is provided a solution composition comprising (A) a cyclic olefin copolymer and (B) an organic solvent, wherein the amount of the structural unit derived from the α-olefin in the cyclic olefin copolymer (A) is adjusted to be 10 mol% or more and 40 mol% or less based on the total structural units and the cyclic olefin copolymer (A) is adjusted to have two or more glass transition temperatures in the range of 0°C to 300°C as determined by solid viscoelasticity measurement by using a copolymer of a cyclic olefin monomer and an α-olefin having 3 or more and 20 or less carbon atoms as the cyclic olefin copolymer (A).SELECTED DRAWING: None
