TUBE USING HYDROGENATED BLOCK COPOLYMER

Document Type and Number:

WIPO Patent Application WO/2017/043542

Kind Code:

A1

Abstract:

A tube including a hydrogenated block copolymer (a), wherein the hydrogenated block copolymer includes in the molecule thereof a polymer block (C) having a conjugated diene compound as a main component thereof, a polymer block (B) having a conjugated diene compound as a main component thereof, and a polymer block (S) having a vinyl aromatic compound as a main component thereof, and, in the hydrogenated block copolymer (a), the content of the polymer block (C) having a conjugated diene compound as a main component thereof is 1-30% by mass, the content of the polymer block (B) having a conjugated diene compound as a main component thereof is 69-98% by mass, the content of the polymer block (S) having a vinyl aromatic compound as a main component thereof is 1-20% by mass, the vinyl bonding amount prior to hydrogenation in the polymer block (C) having a conjugated diene as a main component thereof is 1-25 mol%, the vinyl bonding amount prior to hydrogenation in the polymer block (B) having a conjugated diene as a main component thereof is 60-100 mol%, and the hydrogenation rate of the hydrogenated block copolymer (a) is 80 mol% or greater.
