Beschreibung
Zusammenfassung:	The present invention relates to a continuous or semi-continuous freeze coagulation process for aqueous polymer dispersions, wherein said process comprises a freezing step and a solid-liquid separation step and is further characterized in that it comprises the further step of admixing water and/or water vapor between the freezing step and the solid-liquid separation step. La présente invention concerne un procédé continu ou semi-continu de cryocoagulation de dispersions aqueuses de polymère. Ce procédé comprend une étape de congélation et une étape de séparation solide/liquide. L'invention est caractérisée en ce que le procédé comprend une étape supplémentaire d'ajout d'eau et/ou de vapeur d'eau entre l'étape de congélation et l'étape de séparation solide/liquide.
