Document Type and Number:
WIPO Patent Application WO/2018/139122
Kind Code:
A1
Abstract:
A thermoplastic elastomer composition including 100 parts by mass of a hydrogenated block copolymer (a), 10-50 parts by mass of a polypropylene resin (b), 5-100 parts by mass of a polyphenylene ether resin (c), and 75-200 parts by mass of a non-aromatic softener, wherein the hydrogenated block copolymer (a) contains a hydrogenated block copolymer (a-1) that includes a polymer block A1 composed mainly of at least one vinyl aromatic hydrocarbon compound monomer unit and a polymer block B1 composed mainly of at least one conjugated diene compound monomer unit, the weight-average molecular weight of the hydrogenated block copolymer (a-1) is 100,000-550,000, and the total vinyl aromatic hydrocarbon compound monomer unit content of the hydrogenated block copolymer (a-1) is more than 20% by mass and no more than 50% by mass.
