Abstract
L'invention se rapporte à des membranes qui consistent en des polyamides aromatiques contenant des groupes disulfimide ayant des viscosités relatives eta rel égales ou supérieures à 1,4, mesurées sur une solution à 0,5 % dans de la N-méthyl-pyrrolidone à 20 degrés C, et qui peuvent être utilisées pour l'ultra-filtration et l'osmose inverse.
