Title:
マレイミド系共重合体、その製造方法及びそれを用いた樹脂組成物
Document Type and Number:
Japanese Patent JP7245334
Kind Code:
B2
Abstract:
A maleimide based copolymer, manufacturing method thereof, and a resin composition using the maleimide based copolymer is provided. A maleimide based copolymer includes 40 to 60 mass% of aromatic vinyl monomer unit, 5 to 20 mass% of vinyl cyanide monomer unit, 25 to 50 mass% of maleimide monomer unit, 0.1 to 10 mass% of dicarboxylic anhydride monomer unit; wherein the maleimide based copolymer has a glass transition temperature of 165 to 200°C; and an average number of the dicarboxylic anhydride monomer unit contained in one copolymer molecule is 1 to 30 units. Further, a resin composition is obtained by kneading and mixing the maleimide based copolymer with one or two or more resin selected from the goup including ABS resin, ASA resin, AES resin, and SAN resin. The resin composition is superior in the balance of surface glossiness, heat resistance, impact resistance, and flowability.
