(57) Abstract: [PROBLEMS] To provide a thermoplastic elastomer resin composition having excellent rubber properties such as compression set and the like, excellent mechanical strength and moldability, and free from stickiness. SOLUTION: (a) A block copolymer composed of at least two polymer blocks A mainly containing a vinyl aromatic compound and at least one polymer block B mainly containing a conjugated diene compound, and / Alternatively, 100 parts by weight of a hydrogenated block copolymer obtained by hydrogenating this, (b) Non-aromatic softening agent for rubber 20 to 300 parts by weight, (c) Hydrogenated petroleum resin 10 to 100 parts by weight, (d) peroxide cross-linking olefin resin, and / or copolymer rubber containing the same 1.0 to 100 parts by weight, (e) peroxide decomposing olefin resin, And / or a copolymer containing the same, 10 to 150 parts by weight, and a thermoplastic elastomer resin composition containing 0.1 to 3.0 parts by weight of an organic peroxide. |
