ABSTRACT:
A process is provided for the polymerization of vinyl chloride in a closed mode. According to the process, oxygen is caused to exist in a polymerizer, which is coated with an anti-fouling agent, during an operation in which the polymerization is repeated. The process according to this invention has made it possible to fully exhibit effects of the anti-fouling. This has in turn made it possible to achieve polymerization of vinyl chloride in the closed mode, leading to an improvement in productivity.
