Abstract
L'invention se rapporte à la perméation sélective. Elle concerne un procédé de préparation d'une membrane à perméabilité sélective, selon lequel on rince avec un milieu de rinçage contenant un agent tensio-actif une membrane d'un polymère de condensation contenant un solvant aprotique polaire miscible avec l'eau et un sel soluble dans ledit solvant. Les membranes obtenues ont des propriétés améliorées et sont utiles pour le dessalage d'eau de mer, notamment
