THERMOPLASTIC RESIN COMPOSITION AND RESIN-MOLDED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a thermoplastic polymer composition excellent in impact resistance, hydrolysis resistance and chemical resistance. SOLUTION: This thermoplastic resin composition comprises 5 to 95 mass% of following aliphatic polyester-based resin (A), and 5 to 95 mass% of at least one kind of styrene resin (B) selected from the following (BI) to (BIII). The polyester-based resin (A) has a unit formed by an aliphatic diol and/or alicyclic diol and a unit formed by an aliphatic dicarboxylic acid and/or alicyclic dicarboxylic acid. The styrene-based resin (BI) is a graft copolymer obtained by polymerizing vinyl monomers (b2) containing an aromatic vinyl compound and other copolymerizable vinyl compounds in the presence of a rubbery polymer (b1), the styrene-based resin (BII) is a polymer of the vinyl-based monomer (b2) and the styrene-based resin (BIII) is a mixture of the styrene-based resins (BI) and (BII).
