<p>A permeable, porous synthetic membrane with hydrophilic character for use in ultrafiltration or microfiltration. The hydrophilic character of the membrane is obtained by applying an ageous solution comprising one or more polymers of a molecular weight of between 50,000 and 200,000 and comprising at least two functional hydroxy and/or amino groups, and one or more monomers comprising at least two functional hydroxy and/or amino groups, said aqueous solution having a pH-value of at least 10, followed by removal of excess solution and fixation by applying an isocyanate crosslinking agent dissolved in an organic solvent immiscible with water.</p> |
