Abstract
1497510 Purifying a dispersion of vinyl chloride polymer HOECHST AG 4 May 1976 [16 May 1975] 18174/76 Heading C3P Monomeric matter is removed from an aqueous dispersion of a vinyl chloride polymer by a process in which: 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 and under a pressure of 600 to 1200 mm Mg with superheated steam at 100 to 150 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.
