Bulk PVC composition, bulk PVC polymerization method and apparatus

摘要

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.

主权项

1. A bulk PVC composition comprising a vinyl chloride monomer, an initiator and a bulk PVC particle coating agent,
wherein the PVC particle coating agent is a hydrocarbon alcohol having two to four hydroxyl groups, and wherein the hydrocarbon alcohol having two to four hydroxyl groups is one or more selected from ethylene glycol, diethylene glycol, propylene glycol, hexamethylene glycol, propanetriol, trimethylolpropane and pentaerythritol.
