Abstract
The present invention relates to a vinyl chloride-based polymer, a method of preparing the same, and a plastisol including the vinyl chloride-based polymer. The vinyl chloride-based polymer according to the present invention may exhibit high viscosity characteristics in a low shear region by having particle size distribution characteristics, in which particles having a relatively small particle diameter and particles having a relatively large particle diameter are distributed at a specific ratio, and may exhibit low viscosity characteristics in a high shear region due to small increases in viscosity and stress as shear rate increases, and thus, the vinyl chloride-based polymer may be easily used in a spray coating process. Therefore, the vinyl chloride-based polymer according to the present invention and the method of preparing the same may be easily applied to industries that need them, for example, vinyl chloride-based resin industry for paste processing.
