Abstract
1487876 Removing monomer SOLVAY ET CIE SA 14 Aug 1975 [14 Aug 1974 21 March 1975] 33932/75 Heading C3P Residual monomer is removed from aqueous dispersions of vinyl chloride polymers by heating to a temperature above the glass transition temperature of the polymer and stripping with an inert gas or vapour while maintaining the temperature at least equal to the glass transition temperature. Preferably steam produced by boiling the dispersion is used as stripping medium.
