Abstract
The present invention relates to a method of preparing a vinyl chloride polymer having good thermal stability due to the restraint of dehydrochlorination by heat or ultraviolet rays, and a vinyl chloride polymer prepared thereby. In the preparation method through bulk polymerization, a modifier is introduced to a polymerization process to impart the vinyl chloride polymer with high thermal stability without inducing modification. Therefore, the preparation method via the bulk polymerization of the vinyl chloride polymer and the vinyl chloride polymer prepared thereby according to the present invention may be readily applied to industries requiring thereof such as industries concerning a vinyl chloride resin and the molded article thereof.
