Process for the preparation of grafted semipermeable membranes, of the type that have a water permeability, under pressure under reverse osmosis conditions, at least 10 times higher than the original permeability of the matrix, and which prevent the passage of at least 70%, of the saline content of said water when it is hyperfiltered at the same pressure through said membrane, characterized in that it comprises grafting, on a matrix limitedly permeable to water and constituted by a synthetic compound, molecules which, in the prepared membrane, present groups polar type assets.
