(57) [Abstract] (Correction) [PROBLEMS] A styrene-based thermoplastic resin composition having excellent blow moldability and flame retardancy, and a blow molded product. SOLUTION: In the presence of the rubbery polymer (a), a vinyl cyanide-based monomer (b), an aromatic vinyl-based monomer (c) and, if necessary, other vinyl-based monomer (d). Rubber-containing graft copolymer (I) 1 obtained by graft polymerization of 0 to 50 parts by weight, vinyl cyanide-based monomer (b) and aromatic vinyl-based monomer (c), and the ratio of the triple sequence of vinyl cyanide-based monomer (b) is 10 % Or less and reduced viscosity ηsp / c is 0.5 to 1.5 d Vinyl-based copolymer (II) 10-9 in the range of 1 / g Vinyl-based copolymer (III) consisting of 0 part by weight, aromatic vinyl-based monomer (c), vinyl cyanide-based monomer (b) and / or other vinyl-based monomer (d) 0-80 The flame retardant (IV) is added in an amount of 10 to 95 parts by weight based on 100 parts by weight of the styrene resin composition. |
