摘要： The present invention relates to a method for preparing a rubber-reinforced thermoplastic resin, a rubber-reinforced thermoplastic resin prepared by the same method, and a rubber-reinforced thermoplastic resin composition using the same, wherein the rubber-reinforced thermoplastic resin has excellent heat-sealability and thermal stability maintaining good mechanical properties. More specifically, the present invention relates to a method for preparing a rubber-reinforced thermoplastic resin, a rubber-reinforced thermoplastic resin prepared by the same method, and a rubber-reinforced thermoplastic resin composition using the same characterized by, on the basis of 100 weight parts of total monomer used to prepare graft copolymer, using the mixture comprising 10 to 30 weight parts of a rubber latex having average particle diameter of 0.08 to 0.16 μm and gel content of 65 to 95 weight % and 15 to 45 weight parts of a rubber latex having average particle diameter of 0.26 to 0.34 μm and gel content of 55 to 85 weight %, keeping the weight ratio of vinyl cyanide compound including acrylonitrile to aromatic vinyl compound including styrene from 16/84 to 24/76 as a monomer composition grafted on rubber latex, and adjusting the graft ratio of graft copolymer, i.e. rubber-reinforced thermoplastic resin, from 25 to 65.
