Abstract
The present invention provides a thermoplastic polymer composition capable of exhibiting excellent impact resistance, durability and destaticizing property. The present invention relates to a thermoplastic polymer composition comprising (A) 50 to 95% by mass of an aliphatic polyester-based resin and (B) 5 to 50% by mass of a block copolymer comprising (B1) a hard segment block comprising at least one polymer selected from the group consisting of a polyamide, a polyester, a polyolefin and a polyurethane, and (B2) a soft segment block having an ether bond, with the proviso that a total amount of the components (A) and (B) is 100% by mass. In the preferred embodiment of the present invention, the thermoplastic polymer composition further comprises a specific amount of at least one polymer selected from the group consisting of (C1) a polyester-based resin, (C2) a polyamide-based resin, (C3) an acrylic resin, (C4) a polycarbonate-based resin, (C5) a polyacetal-based resin, (C6) a polyphenylene ether-based resin, (C7) a polyolefin-based resin and (C8) a styrene-based resin.
