The present invention relates to a thermoplastic ABS resin composition for blow molding with improved mold shrinkage, which has drastically reduced occurrence of a post-modification, a size defect, and the like. More specifically, the thermoplastic ABS resin composition for blow molding comprises 0.01 to 2 parts by weight of metallic stearate based on 100 parts by weight of a matrix resin, wherein the matrix resin includes (a) 30 to 50 weight % of graft copolymer in which a conjugated diene-based rubber polymer of a monomodal having 2500 to 5000 Å of an average particle diameter is graft polymerized with a vinyl aromatic compound and a vinyl cyanide compound, and in which the graft polymerized compound is coagulated with a coagulant selected from the group consisting of magnesium sulfate, calcium chloride, aluminium sulfate, or a mixture of at least two thereof; (b) 30 to 60 weight % of AMS copolymer; and (c) 5 to 40 weight % of SAN resin of which weight average molecular weight is 150,000 to 200,000 and a flow index is 8 to 12. |
