Document Type and Number:
WIPO Patent Application WO/2023/171614
Kind Code:
A1
Abstract:
This hydrogenated block copolymer (a) is a hydrogenated product of a block copolymer that has one polymeric block (A) in which a main body thereof is an aromatic vinyl compound unit, and at least one polymeric block (B) in which main bodies thereof are a butadiene unit (Bd) and an isoprene unit (Ip). The hydrogenated block copolymer satisfies the following requirements (I) and (II). (I) The formula (i) is satisfied. (i): α×β>6.500×109 (In formula (i), α represents the weight average molecular weight of the polymeric block (A), and β represents the weight average molecular weight of the hydrogenated block copolymer (a).) (II) The level of vinylation of the polymeric block (B) is less than 35%.
