Abstract:
A hydrogenated block copolymer prepared by hydrogenating a block copolymer that contains a polymer block (A) containing a structural unit derived from an aromatic vinyl compound, a polymer block (B) containing a structural unit derived from farnesene, and a polymer block (C) containing a structural unit derived from a conjugated diene except farnesene, wherein the block copolymer contains at least two above polymer blocks (A), at least one above polymer block (B) and at least one above polymer block (C), and wherein at least one above polymer block (B) is at the terminal, and the hydrogenation rate of the carbon-carbon double bond in the polymer block (B) and the polymer block (C) is 50 mol % or more.
