Abstract

Disclosed are a bulk PVC composition and a bulk PVC polymerization method using the same. According to the present invention, a bulk PVC composition that may effectively prevent generation of fine particles and scale (adhering to a reactor wall) during bulk polymerization and may be prepared without a post-treatment process of an antistatic agent added to easily isolate fine particles after bulk PVC polymerization, and a method and apparatus for polymerizing the same may be provided.
