Title:
THERMOPLASTIC RESIN COMPOSITION, AND MOLDING
Document Type and Number:
Japanese Patent JP2021101004
Kind Code:
A
Abstract:
To provide a thermoplastic resin composition capable of obtaining a molding which has practically sufficient mechanical strength and glossiness and is excellent in chemical resistance.SOLUTION: A thermoplastic resin composition contains a graft copolymer (A), a copolymer (B) containing an aromatic vinyl monomer unit and a vinyl cyanide monomer unit, and a polyester elastomer (C) having aromatic polyester as a hard segment and aliphatic polyether and/or aliphatic polyester as a soft segment. When the total of (A), (B) and (C) is 100 mass%, 10-45 mass% of (A), 89.5-50 mass% of (B) and 0.5-5 mass% of (C) are contained, a ratio (D) of the vinyl cyanide monomer unit in an acetone insoluble matter excluding the (C) and a rubbery polymer is 15-30 mass%, a ratio (E) of the vinyl cyanide monomer unit in the acetone insoluble matter is 32-50 mass%, and a difference between the (E) and the (D) is 9-18 mass%.SELECTED DRAWING: None
