Abstract
Polymer dispersions are subject to a spray treatment to reduce the monomer content thereof. The dispersions are sprayed against the wall of the vessel by means of at least one spray nozzle. The residual monomer content of polymer dispersions is further reduced by spraying them in at least two series connected vessels, conducting the escaping gaseous constituents in one direction and the dispersion in opposite direction from one vessel to the next. The process is little liable to troubles and ensures a very effective monomer removal without thermal damage of the polymer.
