Abstract

The invention relates to a novel process for the production of polyvinyl chloride having a low vinyl chloride monomer content, the latter being removed from a slurry or latex which result from polymerization of vinyl chloride in aqueous media. In the novel process vinyl chloride is removed from a slurry or latex that contains from about 1000 parts to 15,000 parts by weight of vinyl chloride per million parts by weight of the slurry or latex and from 5% to 50% by weight of a polymer selected from the group consisting of polyvinyl chloride and copolymers of vinyl chloride with at least one monomer copolymerizable therewith that comprises a) heating said slurry or latex at a temperature in the range of 70.degree.C. to 125.degree.C.or contacting the slurry or latex with at least one organic liquid at a temperature in the range of 25.degree.C. to 125.degree.C.and b) removing vinyl chloride vapor from the slurry or latex. The resultant aqueous slurry or latex and final polymer product has reduced carcinogenicity.
