摘要：
The present invention relates to a method of preparing a vinyl chloride-based copolymer having excellent plasticity and processability, a vinyl chloride-based copolymer prepared thereby, a thermoplastic resin composition including the vinyl chloride-based copolymer, and a thermoplastic resin molded article prepared from the composition. Since the preparation method may improve copolymerizability with a vinyl chloride-based monomer by continuously adding or dividedly adding an unsaturated fatty acid ester mixture used as a comonomer during the time of specific polymerization conversion rate, the unreacted unsaturated fatty acid ester mixture may be reduced, and, as a result, the conversion rate of the vinyl chloride-based copolymer may be significantly improved. Thus, plasticity and processability of a vinyl chloride-based copolymer prepared by the above method may be significantly improved.
