Martin L Feldman, Robert S Miller: Manufacture of polyvinyl chloride of low vinyl chloride monomer content. Tenneco Chemicals, Evelyn Berlow, March 29, 1977: US04015064 (9 worldwide citation)

Vinyl chloride is removed from a slurry or latex that contains from 100 to 15,000 parts per million of vinyl chloride and 5% to 50% by weight of a vinyl chloride polymer by adding to the slurry or latex from about 0.5% to 20% of its weight of a compound selected from the group consisting of vinyl ac ...

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.
