In the present invention, by specifying the type of emulsifier to be added during polymerization and to the type of initiator to be added before the start of polymerization, the present invention exhibits high viscosity characteristics in the low shear region, and the viscosity decreases as the shear rate increases, indicating low viscosity characteristics. It is to provide a vinyl chloride-based polymer excellent in foaming ratio, foaming color, and foaming cell characteristics when foaming stisol, and a method for manufacturing the same. |
