Vinyl chloride is removed from aqueous slurries prepared by the suspension polymerization of a monomer component that comprises vinyl chloride by heating the slurries at a temperature between 70.degree. C. and the boiling point of water at a pressure in the range of 30 mm Hg absolute to 3 atmosphere ...


Martin L Feldman: Process for the purification of polyvinyl chloride with oxidizing agents. Tenneco Chemicals, Evelyn Berlow, September 2, 1980: US04220754 (3 worldwide citation)

The discoloration of polyvinyl chloride that usually occurs when a slurry containing this polymer is heated at a temperature above 70.degree. C. to reduce its monomer content to less than 10 ppm is minimized or prevented by carrying out the heating step in the presence of an oxidizing agent.
