Abstract (en)
[origin: WO8501222A1] Hydrophobic fine pored membranes are rendered hydrophilic by coating the walls of the pores of the membrane with a hydrophilic material that is deposited on the pore walls by the reaction of first and second components of the hydrophilic material within the membrane. The hydrophilic materials include polyamides and polyimides, polyesters, polyurethanes, phenol/aldehyde resins, polyamide/aldehyde resins and epoxy resins as well as interpolymers and mixtures of those materials.
