A new impact-resistant ABS resin composition is disclosed comprising (1) 100 parts by weight of a graft copolymer of vinyl aromatic monomer and vinyl cyanide monomer, said copolymer being grafted onto butadiene rubber particles of a size of from 0.5 to 2.0 .mu. dispersed in the graft copolymer and (2) 1 to 10 parts by weight of a straight chain saturated polyester having an average molecular weight of from 1000 to 50000. The composition is prepared by the bulk-suspension two stage polymerization of vinyl aromatic monomer and vinyl cyanide monomer in the presence of butadiene rubber component. The polyester is incorporated during either the bulk polymerization stage or the suspension polymerization stage, or it is blended with the ABS polymer after the two stage polymerization is completed.
