Abstract

Procedimiento para desecar polímeros disueltos, mediante el cual se pulveriza un polímero disuelto en un disolvente sobre un lecho de partículas de polímeros desecadas a través de cuyo lecho de partículas del polímero pasa una corriente de gas caliente en condiciones de presión, y temperatura tales eliminarán el disolvente del polímero caracterizado porque dicho polímero en disolución es pulverizado sobre dicho lecho de partículas de polímero a una temperatura inicial inferior a la temperatura de degradación térmica del polímero siendo dicha temperatura suficiente para evaporar la mayor parte del disolvente mediante la evaporación instantánea producida durante esta etapa de pulverización y, además , dicho lecho de partículas de polímero es agitado mecánicamente.
