Abstract

It is known to remove vinyl chloride from a polyvinyl chloride dispersion, latex or slurry by heating said dispersion, latex or slurry under reduced pressure to about 65.degree. C. This treatment reduces the vinyl chloride content to from 1000 ppm to 20,000 ppm. Further treatment results in a vinyl chloride content of about 500 ppm. These levels are unacceptable in light of the health risk to workers dealing with polyvinyl chloride. The present invention overcomes the drawback of the prior art by providing a process for the removal of vinyl chloride from an aqueous dispersion, latex, or slurry that contains from about 1000 parts to 20,000 parts by weight of vinyl chloride per million parts by weight of said dispersion, latex, or slurry and from 5% to 50% by weight of a vinyl chloride polymer selected from the group consisting of polyvinyl chloride and copolymers of vinyl chloride and at least one monomer copolymerizable therewith that comprises maintaining the dispersion, latex, or slurry at subatmospheric pressure while sparging it with a material selected from the group consisting of organic gases, inorganic gases, and organic liquids in which vinyl chloride is at least moderately soluble until the dispersion, latex, or slurry contains less than about 10 parts by weight of vinyl chloride per million parts by weight of said vinyl chloride polymer.
