Abstract
Procedimiento para la obtención de membranas de poliviniltriorganosilanos, del tipo que comprenden una película de polímero de espesor comprendido entre 50 y 500 , que presenta sobra cada una de sus dos caras poros de diámetro comprendido entre 0,05 y 25 , atravesando una parte al menos de estos poros sin discontinuidad la totalidad del espesor de la membrana, caracterizado porque comprende a) formar una solución de un polímero, que comprende una pluralidad de motivos de la fórmula **fórmula** en las que los símbolos, R1,R2 y R3, son idénticos o diferentes, representan un radical alquilo, lineal o ramificado, que contenga de 1 a 12 átomos de carbono, un radical cicloalquilo con 5 o 6 átomos de carbono en el ciclo, un radical aromático monovalente, mono o policíclico, pudiendo estar sustituidos los radicales cicloalquilo y/o arilo por uno o varios radicales alquilo que tengan de 1 a 4 átomos de carbono, y pudiendo representar uno de los radicales R1, R2 y R3 además un átomo de hidrógeno, undisolvente y un no disolvente de este polímero, siendo miscibles entre si disolvente y no disolvente, b) colar la solución a) sobre un soporte provisorio; c) poner la capa así formada en contacto con un líquido de coagulación del polímero antes de cualquier evaporación del disolvente y/o del no disolvente, y d) separar la membrana del soporte y secarla.
