Abstract: PROCESS FOR CONTINUOUSLY REMOVING MONOMERS FROM AN AQUEOUS DISPERSION OF A POLYMER Monomeric matter is removed from an aqueous dispersion of a polymer containing at least 50 weight % of polymerized vinyl chloride. To this end, the dispersion is introduced into the upper portion of a column provided with sieve plates and contacted therein for 10 seconds up to 20 minutes, under 600 up to 1200 mm Hg, with hot steam at 100 up to 150.degree.C flowing countercurrently with respect to the dispersion. The polymer dispersion so treated is removed from the column base portion; and a vaporous matter mixture issuing at the head of the column is condensed stagewise so as to recover an aqueous phase and the monomeric matter.
