    • The present invention relates to an olefinic thermoplastic elastomer composition obtainable by dynamically heat treating 5 to 50 parts by weight of a polypropylene resin (A) and 50 to 95 parts by weight of an alpha -olefinic copolymer (B) having a Mooney viscosity ML1+4 (100 DEG C) of 60 to 250 in the absence of a crosslinking agent. The olefinic thermoplastic elastomer composition is characterized in that the glass transition temperature (Tg) in dynamic visco-elasticity measurement derived from the polypropylene resin (A) is lower than that of the polypropylene resin (A) itself and that the alpha -olefinic copolymer (B) is at least one selected from the following (b-1) and (b-2): (b-1) ethylene- alpha -olefinic copolymers which have an ethylene content of 51 to 60 mol% to the total amount of the ethylene- alpha -olefinic copolymer-constituting ethylene and alpha -olefin other than ethylene, (b-2) propylene- alpha -olefinic copolymers which have a propylene content of 60 to 90 mol% to the total amount of the ethylene- alpha -olefinic copolymer-constituting propylene and alpha -olefin other than propylene.

    • PROBLEM TO BE SOLVED: To provide a laminate structure body having a laminate structure at least as a part of it, the laminate structure obtained by strongly bonding a layer containing an olefin-based polymer as a major constituent to at least one layer of a material selected from a polar vinyl-based plastic, an engineering plastic, an organism-based polymer, a thermoplastic elastomer and the like via a hot-melt type adhesion layer containing a specific hybrid polymer. SOLUTION: The laminate structure body has a structure at least as a part of it, wherein the structure comprises a layer (A) containing the olefin-based polymer as a major constituent, a layer (B) containing the hybrid polymer [P]composed of a polyolefin segment [S 1 ] and a polar polymer segment [S 2 ], and at least one layer (C) of a material selected from the polarvinyl-based plastic, an aromatic vinyl-based polymer, a polyester, a polyamide, a polycarbonate, the engineering plastic, the organism-based polymer and the like, and the layer A, the layer B and the layer C being laminated in this order.
