The present invention relates to a method of preparing a thermoplastic resin, a thermoplastic resin prepared by the same, and a thermoplastic resin composition including the same. More specifically, the method of the present invention includes a step of performing acid coagulation of emulsion polymerization latex, a step of treating coagulated slurry with a base and performing dehydration, and a step of adding a metal salt and water to dehydrated wet powder to adjust pH to 9 or more. According to the present invention, the method may increase the productivity of a thermoplastic resin, and the thermoplastic resin prepared by the method has excellent mechanical strength, thermal stability, and appearance properties. In addition, when the thermoplastic resin of the present invention is used in coating, the thermoplastic resin has an effect of improving the adhesive strength and appearance quality of a coating film. |
