THERMOPLASTIC RESIN COMPOSITION AND RESIN MOLDED ARTICLE

摘要

Disclosed is a thermoplastic resin composition which enables to obtain a molded article excellent in impact resistance, separation resistance and surface appearance. Specifically disclosed is a thermoplastic resin composition containing 5-95% by mass of an aliphatic polyester (A), 4-94% by mass of an olefin resin (B) and 1-40% by mass of at least one aromatic vinyl polymer (C) selected from aromatic vinyl polymers (C1)-(C3) defined below (with the total of the component (A), the component (B) and the component (C) being 100% by mass). The aromatic vinyl polymer (C1) is an elastomer composed of a block copolymer containing a polymer block mainly composed of an aromatic vinyl compound and a polymer block mainly composed of a conjugated diene compound; the aromatic vinyl polymer (C2) is an elastomer obtained by hydrogenating the aromatic vinyl polymer (C1); and the aromatic vinyl polymer (C3) is a graft copolymer obtained by polymerizing a vinyl monomer containing an aromatic vinyl compound in the presence of an olefin polymer.
