METHOD FOR SUSPENSION POLYMERIZATION OF POLYVINYLCHLORIDE

摘要

The present invention relates to a vessel and a process for polymerizing vinyl chloride in suspension. The vessel the inner surfaces of which consist of stainless steel or are plated with a noble metal comprises at least one cathode in contact with the reaction medium and insoluble therein and as anode the metallic inner surface of the vessel, the cathode and anode being connected over an external source of current. The polymerization is carried out with electrolytic generation of hydrogen and oxygen from the polymerization medium. The polymerization vessel and process according to the invention suppress completely or substantially the formation of wall deposits.
