Abstract
Process for removing the residual vinyl chloride monomer present after polymerisation in vinyl chloride polymers in the form of an aqueous dispersion which is heated to a temperature at least equal to the glass transition temperature of the polymer and subjected to stripping by an inert fluid while being maintained at a temperature at least equal to the glass transition temperature of the polymer.
