Abstract
Composición fluida adecuada para la producción y reparación de membranas de intercambio iónico. Composición fluida que contiene copolímero de intercambio iónico perfluorado con grupos funcionales -SO{sub,3}M, iones de M-hidrógeno o iones de metales alcalinos (EM mayor de 900) y un disolvente orgánico polar o una mezcla de un disolvente orgánico polar y un disolvente no polar y, como copolímero de intercambio iónico perfluorado, la composición contiene un copolímero de intercambio iónico perfluorado con un grado de cristalinidad del 2 al 10% y una relación entre la densidad del copolímero de intercambio iónico indicado y la densidad del copolímero perfluorado original en forma no iónica de 0,90-0,97. La relación de los componentes es, en % en masa: Copolímero de intercambio iónico perfluorado 1- 35 Disolvente orgánico polar o mezcla de disolvente orgánico polar con disolvente no polar 65-99. Tales composiciones se usan en la producción y reparación de membranas de intercambio iónico (IEM), que se usan en la electrólisis alcalina con cloro o en la electrólisis acuosa en celdas de separación de combustible y gas.
