Patent ID: 8722799

Claim:
A crosslinked thermoplastic elastomer composition comprising 5 to 70 parts by mass of (C) a hydrogenated product of a block copolymer having at least one conjugated diene monomer unit block and at least one vinyl aromatic monomer unit block, and 20 to 150 parts by mass of (D) an olefin-based resin, based on 100 parts by mass of the total of (A) an ethylene-a-olefin copolymer comprising an ethylene unit and an a-olefin unit having 3 to 20 carbon atoms, and (B) a copolymer having at least one hydrogenated copolymer block mainly composed of a conjugated diene monomer unit and vinyl aromatic monomer unit, wherein at least one of tan δ peak temperature of the (B) component is present within a range of from −25 to 40 ° C., the hydrogenated product of a block copolymer (C) comprises at least two hydrogenated products of block copolymers (C-1) and (C-2), wherein the (C-1) is a hydrogenated product in which a content of the vinyl aromatic monomer unit block is 20% by mass or more and 50% by mass or less, and the (C-2) is a hydrogenated product in which a content of the vinyl aromatic monomer unit block is more than 50% by mass and 80% by mass or less, and a mass ratio ((A)/(B)) of the (A) component and the (B) component is from 20/80 to 75/25.
