(57) [Summary] [Purpose] To provide a rubber-reinforced thermoplastic resin having good paintability, impact resistance, and thermal stability. [Structure] In the presence of 20 to 80 parts by weight of a rubber-like polymer, 30 to 75% by weight of an aromatic vinyl compound, 25 to 70% by weight of a vinyl cyanide compound, and 0 to another vinyl compound which is copolymerizable therewith. A rubber obtained by polymerizing 80 to 20 parts by weight of a monomer component composed of 30% by weight (however, 100% by weight in total), and 3 chains of 11% or less of vinyl cyanide compound chains in a graft chain. Reinforced thermoplastic resin. |
