<p>The membranes are obtained on a microporous support of synthetic polymer for the desalting and purification of water and other reverse osmosis processes, and they are essentially characterized in that they are comprised of monomers which are aromatic diamines of the type carring an electroacceptor group, nitro, halogen or others which do not react with amino groups or acylchlorides in the interfacial polycondensation; their dissolution being obtained through protonation of the amino groups by means of acid reagents or by addition of water miscible or partially water miscible solvents.</p> |
