Abstract
The present invention relates to a vinyl chloride-based polymer which has improved thermal stability and a method for preparing the same. The vinyl chloride-based polymer includes silicate compound derived units, and a dehydrochloric acid (dehydrochlorination) reaction due to heat or ultraviolet rays may be suppressed, and thus, thermal stability may be improved, and discoloration and deformation of physical properties may be prevented. Accordingly, the vinyl chloride-based polymer and the method for preparing the same may be readily applied to industries requiring a vinyl chloride-based polymer, for example, industries related to a vinyl chloride-based resin and molded articles thereof.
