Abstract (en)
[origin: EP2486974A1] Nanofiltration membrane comprises a porous supporting membrane, where the surface of supporting membrane is coated with an emulsion polymerization prepared polymer particles having a particle diameter of less than 70 nm, preferably 40-50 nm. Independent claims are also included for: (1) producing a nanofiltration membrane having a porous supporting membrane, comprising applying a dispersion (latex) of polymer particles prepared by emulsion polymerization to the supporting membrane and forming a polymer layer on separation-active layer of the support membrane; and (2) use of polymer particles obtained by emulsion polymerization with mean particle diameter less than 70 nm, preferably 40-50 nm for the preparation of a nanofiltration membrane.
