<P>PROBLEM TO BE SOLVED: To provide a thermoplastic elastomer resin composition which has a high joining strength, is excellent in molding processability including injection molding, and can be thermally fused in joining of dissimilar molded bodies. <P>SOLUTION: The thermoplastic elastomer resin composition is obtained by blending: 56 to 99 wt.% of a polyester block copolymer (A) having, as main constituents, a high-melting point crystalline polymer segment (a1) composed mainly of a crystalline aromatic polyester unit and a low-melting point polymer segment (a2) composed mainly of an aliphatic polyether unit and/or an aliphatic polyester unit, and having a melting point of <210°C; 1 to 40 wt.% of a polyvinylbutyral resin (B); 0.01 to 5.0 wt.% of a silane coupling agent (C); and 0.01 to 5.0 wt.% of a heat-resistive agent (D). <P>COPYRIGHT: (C)2012,JPO&INPIT |
