Title:
MODIFIED HYDROGENATED BLOCK COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2021/172189
Kind Code:
A1
Abstract:
Provided are polyolefins that are soluble in organic solvents, have transparency, rigidity, and heat resistance, have excellent adhesiveness with base materials such as metals, and have suppressed generation of toxic gas during combustion. A modified hydrogenated block copolymer which is a product of modification of a hydrogenated block copolymer by an unsaturated carboxylic acid and/or unsaturated carboxylic anhydride, wherein a modified hydrogenated block copolymer is used in which the hydrogenated block copolymer is a product of hydrogenation of a copolymer including a polymer block comprising an aromatic vinyl monomer unit and a polymer block comprising a conjugated diene monomer unit; the hydrogenated product of the polymer block comprising an aromatic vinyl monomer unit is a hydrogenated aromatic vinyl polymer block unit having a hydrogenation level of 90% or higher; and the hydrogenated product of the polymer block comprising a conjugated diene monomer unit is a hydrogenated conjugated diene polymer block unit having a hydrogenation level of 95% or higher.
