Title:
水素化ブロック共重合体を用いたチューブ
Document Type and Number:
Japanese Patent JP6563503
Kind Code:
B2
Abstract:
A tube including a hydrogenated block copolymer (a), wherein
the hydrogenated block copolymer (a) includes, in a molecule, a polymer block mainly including a conjugated diene compound (C), a polymer block mainly including a conjugated diene compound (B), and a polymer block mainly including a vinyl aromatic compound (S),
a content of the polymer block mainly including the conjugated diene compound (C) is 1 to 30% by mass, a content of the polymer block mainly including the conjugated diene compound (B) is 69 to 98% by mass, and a content of the polymer block mainly including the vinyl aromatic compound (S) is 1 to 20% by mass in the hydrogenated block copolymer (a), and
the polymer block mainly including a conjugated diene compound (C) has a vinyl bond content before hydrogenation of 1 to 25 mol%, the polymer block mainly including the conjugated diene compound (B) has a vinyl bond content before hydrogenation of 60 to 100 mol%, and the hydrogenated block copolymer (a) has a ratio of hydrogenation of 80 mol% or more.
