<p>PROBLEM TO BE SOLVED: To provide a thermoplastic elastomer resin composition that is flexible, hardly causes bleedout, reduces an amount of gas generated during molding, is excellent in releasability from a mold, has good appearance of a molded article, and generates little burrs in a molded article.SOLUTION: The thermoplastic elastomer resin composition includes: 20-80 wt% of (A) a polyether ester block copolymer having as constituent components (a1) a high-melting-point crystalline polymer segment comprising a crystalline aromatic polyester and (a2) a low-melting-point polymer segment composed of an aliphatic polyether unit; 10-50 wt% of (B) a thermoplastic elastomer having a styrenic elastomer having a crosslinked structure as a disperse phase dispersed in a matrix resin; and 10-50 wt% of (C) a graft copolymer produced by graft-polymerizing a vinyl monomer with a rubbery polymer.</p> |
