Abstract

Un procedimiento para preparar membranas de poliamida insolubles en alcohol, hidrófilas y sin piel, que comprende preparar una solución de una resina de poliamida insoluble en alcohol en un disolvente de poliamidas; inducir la nucleación de la solución por adición controlada a la solución de un líquido no disolvente de la resina de poliamida, en condiciones controladas de concentración, temperatura, velocidad de adición, y grado de agitación para obtener un precipitado visible de partículas de resina de poliamida, formando así una solución de colada; extender la solución de colada sobre un substrato para formar una película delgada de la misma sobre el substrato; poner en contacto y diluir la película de solución de colada con un líquido no disolvente de la resina de poliamida, precipitándose de este modo resina de poliamida a partir de la solución de colada en la forma de una membrana delgada sin piel; lavar la membrana para separar el disolvente; y secar la membrana resultante.
