Abstract
An object of the present invention is to provide a copolymer for a compatibilizer capable of increasing impact resistance strength, heat resistance and toughness without lowering fluidity. The copolymer for a compatibilizer contains polyamide resin and at least one resin selected from ABS resin, SAN resin, ASA resin, AES resin. A resin composition comprising 0.5 to 11 mass % of copolymer (A) for a polymer blend compatibilizer, 25 to 60 mass % of polyamide resin (B), and 29 to 74.5 mass % of resin (C) is formed. The resin (C) is at least one resin selected from ABS resin, SAN resin, ASA resin, and AES resin. The copolymer (A) for a polymer blend compatibilizer has 30 to 60 mass % of a maleimide-based monomer unit, 35 to 69 mass % of a styrene-based monomer unit, 1 to 5 mass % of unsaturated dicarboxylic anhydride monomer unit, and has a weight average molecular weight (Mw) of 60,000 to 125,000.
