Abstract
The object of the present invention is to provide a thermoplastic polymer composition which is excellent in the impact resistance, a fracture morphology and rigidity, as well as has a possibility of the effect for reducing environmental load.The thermoplastic resin composition comprises 15 to 85% by mass of aliphatic polyester-based resin (A) comprising the following (AI) and (AII) components, and The above (AI) is an aliphatic polyester-based resin having units formed from an aliphatic diol and/or an alicyclic diol and an aliphatic dicarboxylic acid (including derivatives thereof) and/or an alicyclic dicarboxylic (including derivatives thereof) as repeating units, and the above (AII) is a polylactic acid-based aliphatic polyester resin having not less than 70 mol % of lactic acid unit content.The above (BI) is a graft copolymer obtained by polymerizing vinyl-based monomers (b2) comprising an aromatic vinyl compound and another vinyl compound copolymerizable therewith in the presence of rubber polymer (b1), the above (BII) is a polymer of vinyl-based monomers (b2), and the above (BIII) is a mixture of said (BI) and (BII).
