Abstract
A method for producing a vinyl chloride-based polymer, wherein the vinyl chloride-based polymer is produced by sequentially adding a first emulsifier and a second emulsifier, which are different from each other, during polymerization and using a succinate compound as a first emulsifier. The method provides improved processability by achieving low-viscosity properties when plastisol is mixed using the produced polymer, and improved fogging properties by suppressing generation of volatile organic compounds.
