Abstract

1487820 Removing monomer from polyvinyl halide slurries CONTINENTAL OIL CO 2 March 1976 [19 June 1975] 08365/76 Heading C3P Vinyl halide is removed from a polyvinyl halide-containing slurry by passing a gas through the slurry, desirably at elevated temperature, e.g. at 50-100‹ C. Nitrogen is the preferred gas; others mentioned are air, CO 2 , and methane or natural gas. The process is of particular application in the treatment of water-PVC slurries.
