Abstract
MEJORAS INTRODUCIDAS EN EL OBJETO DE LA PATENTE PRINCIPAL N 480.577 PRESENTADA EL 14 DE MAYO DE 1.979 POR: _(UN PROCEDIMIENTO PARA PREPARAR MEMBRANAS DE POLIAMIDA . CONSISTE EN EMPLEAR UNA RESINA DE POLIAMIDA CON UNA PROPORCION DE GRUPOS METILENO CH A GRUPOS AMIDA NHCO (CH :NHCO) EN UN INTERVALO DE 5:1 A 7:1. EL DISOLVENTE EMPLEADO EN LA DISOLUCION DE LA RESINA DE POLIAMIDA ES ACIDO FORMICO Y EL NO-DISOLVENTE ES AGUA; LA PELICULA DE DISOLUCION DE RESINA DE POLIAMIDA, SE PONE EN CONTACTO CON EL NO-DISOLVENTE SUMERGIENDO LA PELICULA SOBRE EL RESORTE DEL SUSTRATO EN UN BAÑO DE NO DISOLVENTE QUE COMPRENDE AGUA CON ACIDO FORMICO. EL BAÑO COMPRENDE DE 20 A 55% DE DISOLVENTE DE RESINA. EL SUSTRATO EMPLEADO ES UNA LAMINA FIBROSA DE POLIESTER.
