Title:
HYDROGENATED COPOLYMER, RESIN COMPOSITION, MOLDED BODY AND ADHESIVE FILM
Document Type and Number:
WIPO Patent Application WO/2021/261241
Kind Code:
A1
Abstract:
A hydrogenated copolymer (X) which contains a hydrogenated copolymer (A) and a hydrogenated copolymer (B), while satisfying the requirements (1) to (4) described below. (1) The hydrogenated copolymer (A) has a random copolymer structure that is composed of a conjugated diene compound and a vinyl aromatic compound; and the content of the vinyl aromatic compound in the hydrogenated copolymer (A) is from 10% by mass to 80% by mass. (2) The hydrogenated copolymer (B) has a random copolymer structure that is composed of a conjugated diene compound and a vinyl aromatic compound; and the content of the vinyl aromatic compound in the hydrogenated copolymer (B) is from 10% by mass to 80% by mass. (3) The ratio of the (Mn1) of the hydrogenated copolymer (A) to the (Mn2) of the hydrogenated copolymer (B), namely Mn1/Mn2 is less than 0.25, with the Mn1 satisfying 1,000 ≤ Mn1 ≤ 40,000. (4) The mass ratio of the content of the hydrogenated copolymer (A) to the content of the hydrogenated copolymer (B), namely (A)/(B) is from 5/95 to 50/50.
