Abstract

Procedimiento de coagulación por congelación continuo o semicontinuo para una dispersión acuosa polimérica que comprende una etapa de congelación y una etapa de separación sólido-líquido, caracterizado porque el procedimiento la etapa adicional comprende: - adición de agua y/o vapor de agua entre la etapa de congelación y la etapa de separación sólido-líquido, estando caracterizada la etapa de separación sólido-líquido por un factor de separación P según la fórmula **(Ver fórmula)** en la que mH2O,mec representa la cantidad de agua separada mecánicamente, es decir, la cantidad de la fase acuosa separada, y mH2O,tot representa la cantidad de agua total como suma del agua, es decir, de la fase acuosa de la dispersión polimérica acuosa utilizada originariamente y del agua y/o vapor de agua añadidos, y siendo P >= 0,55, preferiblemente >= 0,8, preferiblemente >= 0,93, más preferiblemente >= 0,95.
