Abstract

EL OBJETO DE LA INVENCION ES UNA MEMBRANA HIDROFILA SINTETICA EN FORMA DE FIBRAS HUECAS O DE MEMBRANAS PLANAS PARA LA DIALISIS Y/O ULTRAFILTRACION, QUE CONTIENE UNA MEZCLA DE POLISULFONA Y POLISULFONA SULFONADA, EN DONDE LA MEZCLA CONTIENE UN 65 A 95% EN PESO DE POLISULFONA SULFONADA, DADO EL CASO COMO SAL DEL ACIDO SULFONICO, Y UN 35 A 5 % EN PESO DE POLISULFONA NO SULFONADA. PREFERENTEMENTE SE AGREGAN A LA MEZCLA DE POLISULFONA Y POLISULFONA SULFONADA, ANTES DE LA FORMACION DE LA MEMBRANA, HASTA UN 12% EN PESO DE POLIMEROS SOLUBLES EN AGUA, REFERIDOS A LA MEZCLA TOTAL. EL OBJETO TAMBIEN ES UN PROCEDIMIENTO PARA LA PRODUCCION DE UNA MEMBRANA HIDROFILA SEMEJANTE.
