    摘要： The present invention relates to a vinyl chloride-based copolymer which has excellent processability and is thus capable of providing a molded article having excellent appearance characteristics such as transparency, a method for producing the same, a thermoplastic resin composition comprising the same, and a thermoplastic resin molded article made from the thermoplastic resin composition. The vinyl chloride-based copolymer according to the present invention comprises N-vinyllactam-based polymer compound-derived units and unsaturated fatty acid ester-derived units in an appropriate ratio, and thus structural stability and processability can be improved by the units derived from the N-vinyllactam-based polymer, and plasticity and processability can be further improved by the action of an internal plasticizer of the unsaturated fatty acid ester-derived units. Thus, the vinyl chloride-based copolymer according to the present invention can be easily applied to industries requiring the same.
