Summary: | The present invention is an invention for improving static electricity of a vinyl chloride-based polymer, comprising the steps of (A) initiating a polymerization reaction by introducing a vinyl chloride-based monomer in the presence of a polymerization initiator; and (B) adding a cationic emulsifier comprising at least one selected from ester-based quaternary ammonium salts and imidazoline-based quaternary ammonium salts at a time when a polymerization conversion rate is 80% or more and inducing a reaction. In addition, the present invention relates to the vinylchloride-based polymer, which comprises the cationic emulsifier including at least one selected from the ester-based quaternary ammonium salts and the imidazoline-based quaternary ammonium salts, or a component derived from the cationic emulsifier.
