description The present invention relates to a method of preparing an ABS graft copolymer and a method of preparing a thermoplastic resin composition including the ABS graft copolymer. More specifically, the present invention relates to a method of preparing an ABS graft copolymer, in which a predetermined amount of a vinyl aromatic compound and a predetermined amount of a vinyl cyanide compound are grafted to a small-diameter rubber latex before enlarging particle size of the small-diameter rubber latex is performed, and then enlarging particle size of the small-diameter rubber latex is performed by adding a certain amount of a polymer coagulant, and to a method of preparing a thermoplastic resin composition including the ABS graft copolymer. According to the present invention, latex stability may be improved, and an ABS graft copolymer having excellent impact resistance may be prepared.
