PROBLEM TO BE SOLVED: To obtain the subject composition consisting of each a specific styrene-based thermoplastic resin composition and an aromatic polyester resin, having a blow-molding property suitable especially for a large-sized blow-molded product, excellent in chemical resistance and impact resistance, and used for an automotive part, etc. SOLUTION: This resin composition for blow-molding consists of (A) 20-80wt.% styrene-based thermoplastic resin composition consisting of (i) a rubber containing a graft copolymer obtained by graft copolymerizing (b) an aromatic vinyl-based monomer with (c) a cyanized vinyl-based monomer and further, as necessary, (d) another vinyl-based monomer copolymeirzable therewith in the presence of (a) a diene-based rubbery polymer, (ii) a vinyl-based copolymer obtained by copolymerizing the components (a) with (b) and (c) and having [η]=0.7-1.2 intrainsic viscosity (solvent: methyl ethyl ketone, and measured at 30 deg.C), and (iii) a vinyl-based copolymer containing epoxy group obtained by copolymerizing (d) a vinyl-based monomer containing an epoxy group with the components (a), (b) and (c) and having 0.001-14wt.% copolymerized amount of the component (d), and (B) 80-20wt.% aromatic polyester resin having a relative viscosity (solvent: o-chlorophenol, and measured at 25 deg.C) ofηr=1.5-2.2.
