Beschreibung
Zusammenfassung:	The present invention relates to a continuous or semi-continuous freezing coagulation method for aqueous polymer dispersions. The method comprises a freezing step and a solid-liquid separation step and is furthermore characterized in that it comprises the additional step of adding water and/or water vapor between the freezing step and the solid-liquid separation step. La presente invención está relacionada con un proceso continuo o semi-continuo de coagulación por congelación para dispersiones acuosas de polímero, en el cual dicho proceso comprende un paso de congelación y uno de separación de líquidos y sólidos, y se caracteriza además en que comprende un paso adicional de mezclar agua y/o vapor de agua entre el pasos de congelación y el de separación de sólidos y líquidos.
