Abstract

PARTIENDO DESDE UNA MEZCLA DE AL MENOS UN POLIMERO HIDROFOBICO Y UN POLIMERO HIDROFILICO, ESTOS POLIMEROS SE DISUELVEN PRIMERO EN UN DISOLVENTE APROPIADO O MEZCLA DE DISOLVENTES Y A CONTINUACION SE COAGULAN EN UN BAÑO DE COAGULACION. DE ACUERDO AL INVENTO, SE PREPARA UNA MEMBRANA MAS O MENOS HIDROFILICA MEDIANTE LA ELIMINACION DE LA MEMBRANA ASI OBTENIDA DEL BAÑO DE COAGULACION Y A CONTINUACION MEDIANTE LIXIVIACION DE AL MENOS UNA PARTE DEL POLIMERO HIDROFILICO DE LA MATRIZ, SEGUIDO ALTERNATIVAMENTE POR LA HIDROFOBIZACION. DICHA LIXIVIACION DEL POLIMERO HIDROFILICO SE PRODUCE MEDIANTE TRATAMIENTO DE LA MEMBRANA CON UN AGENTE OXIDANTE/HIDROLIZANTE. EL INVENTO COMPRENDE ADEMAS MEMBRANAS MICROPOROSAS, PLANAS O TUBULARES, O EN FORMA DE FIBRAS HUECAS, QUE TIENEN UNA BUENA RESISTENCIA QUIMICA Y BUENA FORTALEZA MECANIZA.
