    摘要： Provided is a flame-retardant thermoplastic resin composition in which any halogenated flame retardant is not used but a phosphoric flame retardant is used, which has flame retardancy meeting U.S. UL Standard 94 V-2, which exhibits excellent dripping performance during burning, and which is excellent in balance between properties. The flame-retardant thermoplastic resin composition contains 100 parts by mass of a copolymer mixture containing a graft copolymer (A) obtained by graft-polymerizing a rubbery polymer, a vinyl cyanide compound, and a copolymerizable vinyl compound and a vinyl copolymer (B) which is obtained by copolymerizing the vinyl cyanide compound and the copolymerizable vinyl compound and which has a mass-average molecular weight of 90,000 to 160,000 and 5 to 20 parts by mass of a phosphoric flame retardant (C) blended with the copolymer mixture. The content CB 1 of vinyl cyanide units in the acetone-insoluble fraction of the copolymer mixture is 22.0% to 32.0% by mass, the content CB 2 of vinyl cyanide units in the acetone-soluble fraction thereof is 22.0% to 34.0% by mass, and |CB 1 - CB 2 | is 0% to 3.0% by mass.

    摘要： Provided are a graft copolymer which has good moldability and good continuous moldability and with which a thermoplastic resin molded article having excellent impact resistance can be produced, a method for producing the graft copolymer, and a thermoplastic resin composition including the graft copolymer. A graft copolymer (B-I) produced by grafting at least one vinyl monomer (b-I) selected from the group consisting of an aromatic vinyl, an alkyl (meth)acrylate, and a vinyl cyanide to a rubbery polymer mixture including a rubbery polymer (A-I) and a hydrophobic substance, the rubbery polymer (A-I) including an alkyl (meth)acrylate unit and a multifunctional monomer unit copolymerizable with the alkyl (meth)acrylate, the hydrophobic substance having a kinematic viscosity of 5 mm 2 /s or more at 40°C or a kinematic viscosity of 2 to 4 mm 2 /s at 100°C, a principal constituent of the hydrophobic substance being a hydrocarbon. A thermoplastic resin composition including the graft copolymer (B-I). A molded article produced using the thermoplastic resin composition.
