Abstract:
The present invention provides a method for preparing a vinyl chloride-based polymer and a vinyl chloride-based polymer prepared thereby, the method comprising a step for performing suspension polymerization of a monomer for preparing a vinyl chloride-based polymer in the presence of a polymerization initiator, a dispersant, and water soluble cellulose ether, wherein the dispersant includes a mixture of two or more kinds of polyvinyl alcohol having different degrees of saponification, and the mole average degree of saponification of the polyvinyl mixture is from 76 mol % to 80 mol %, and the water soluble cellulose ether has a gel point of 60° C. to 90° C. and is added before the initiation of polymerization or at a time in which the polymerization conversion rate is 70% or less.

Claim (Index 5):
The method of  claim 1 , wherein the dispersant is added before the initiation of the polymerization or at a time in which the polymerization conversion rate is 10% or less.
