PROBLEM TO BE SOLVED: To provide an ABS resin composition having an excellent surface property of its blow-molded item and an excellent balance of a melt throwing property at its blow molding, a draw-down resistance and an impact resistance. SOLUTION: This composition comprises (I) 1-30 pts.wt. of a composition ((A)+(B)=100 pts.wt.) comprising (A) 5-100 pts.wt. of a graft copolymer, 100 pts.wt. of which is obtained by polymerizing 5-95 pts.wt. of a mixture of 0.1-30.2% of anα,β-unsaturated acid glycidyl ester, 9.9-40% of vinyl cyanide, 59.9-90% of an aromatic vinyl and 0-30% of a copolymerizing vinyl compound with 5-95 pts.wt. of a rubber polymer and (B) a copolymer comprising 10-40% of vinyl cyanide, 50-90% of an aromatic vinyl and 0-30% of a copolymerizing vinyl compound and (II) 70-99 pts.wt. of an ABS resin. The reduced viscosity of its soluble to methyl ethyl ketone is 0.3-1.5 dl/g (N,N-dimethylformamide 0.3 wt.% solution).
