Abstract
The present invention relates to a method of preparing a thermoplastic resin, a method of preparing a thermoplastic resin composition including the same, and a method of manufacturing an injection-molded article using the thermoplastic resin composition. By using a mixture of molecular weight modifiers having different reactivities according to the present invention, coagulation may be performed using a small amount of coagulant, productivity may be increased, and a molded article, which is manufactured using a thermoplastic resin, having excellent appearance characteristics along with superior mechanical strength, processability, or the like may be provided.
