THERMOPLASTIC POLYMER COMPOSITION AND MOLDED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a thermoplastic polymer composition from which a molded article excellent in antistaticity, antistaticity persistence, impact resistance and durability can be obtained. SOLUTION: This thermoplastic polymer composition comprises: 40 to 97% by mass of (A) an aliphatic polyester; and 3 to 60% by mass of (B) a thermoplastic polyurethane elastomer (wherein the total of the component (A) and the component (B) is 100% by mass). Further, this thermoplastic polymer composition comprises a styrene-based resin (C) obtained by polymerizing an aromatic vinyl compound or an aromatic vinyl compound and another vinyl monomer (C2) copolymerizable with an aromatic vinyl compound in the presence or absence of a rubbery polymer (C1) in an amount of 5 to 200 parts by mass relative to 100 parts by mass of the total of (A) the aliphatic polyester and (B) the thermoplastic polyurethane elastomer.
