<p><P>PROBLEM TO BE SOLVED: To provide a thermoplastic elastomer composition which exhibits a good mold-releasing property, after injection-foaming molded, is excellent in the fineness and uniformity of foamed cells, and is good in adhesiveness to thermoplastic resin layers, when forming laminates. <P>SOLUTION: The thermoplastic elastomer composition for injection molding comprises the components (A), (B), (C) and (D): (A) is the hydrogenation product of a block copolymer comprising a block (a) composed from monomer units based on an aromatic vinyl compound, and a block (b) composed from monomer units based on a conjugated diene compound and having a 1,2-bond content of≥60%, (B) is a propylenic resin, (C) is a mineral oil softening agent, and (D) is ethylene-propylene copolymer rubber having a Mooney viscosity (ML1+4, 100°C) of 20 to 200 and having an ethylene-based monomer unit content of 40 to 80 wt.% (wherein, the total amount of the copolymer rubber is 100 wt.%). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
