Abstract

A procedure for removing residual vinyl chloride from polymerization in vinyl chloride polymers that are in the form of an aqueous dispersion, characterized in that the aqueous polymer dispersion is brought to a temperature at least equal to that of glass transition temperature of the polymer and it is subjected to entrainment by an inert fluid while maintaining a temperature at least equal to the glass transition temperature of the polymer.
