Abstract

Una membrana con una superficie hidrofílica formada de una mezcla polimérica de una polisulfona y un copolímero y de oxido de etileno/oxido de propileno con un corte de peso molecular de más de 20,000 puede hacerse agregando agentes modificadores del poro a la mezcla polimérica y/o agentes para agrandar el poro al líquido de enfriamiento usado para moldear la membrana de la solucion polimérica.
