The present work deals with verification stability of the prepared anion-exchange membrane with surface modification in the time. The surface modification of a commercial ultrafiltration poly(ethersulfone) membrane was carried out graft polymerization. Poly(styrene-co-divinylbenzene-co-4-vinylbenzylchloride) surface layer was covalently attached onto commercial ultrafiltration support layer. The membrane was tested from the point of view of water content, ion-exchange capacity, specific resistance, permselectivity, FT-IR spectroscopy and SEM analysis. The tested characteristics (IEC, permselectivity, resistances, structure) of the prepared membrane were same after one year from preparation. The prepared membranes can find use in electrodialysis processes.
