To obtain the subject composition excellent in impact resistance, blow molding processability and balance in antistatic properties and useful for large hollow resin parts, etc., for automobiles and motorcycles, by consisting of a specific copolymer composition and an antistatic agent.
This thermoplastic resin composition for blow molding consists of (A) 10-50 pts.wt. of a graft copolymer obtained by graft polymerizing 80-20 pts.wt. of a mixture comprising a specific ratio of a vinyl cyanide-based monomer (M1), an aromatic vinylbased monomer (M2) and an unsaturated carboxylic acid alkyl onto 20-80 pts.wt. of a rubbery polymer having 0.05-0.50μm weight average particle size, (B) 10-80 pts.wt. of a vinyl cyanide-based polymer obtained by copolymerizing M1 and M2 in a specific ratio and having 0.5-1.5dl/g reduced viscosity, (C) 0.05-30 pts.wt. of a polyether-ester-amide or an anionic surfactant and (D) 0-50 pts.wt. of a vinyl-based copolymer obtained by copolymerizing M1, M2 and other vinyl-based monomers in a specific ratio. The sum total amount of the components A-D is adjusted to 100 pts.wt.
