Membranes were prepared from poly(styrene‐co‐maleic acid) under different conditions and characterized by measuring thickness, swelling, electrical resistance, membrane potential and permselectivity. Permeability coefficients of KCl, NaCl, Na 2 SO 4 , NaOH, urea and creatinine were evaluated from dialysis experiments. The charged membranes facilitated the active transport of alkali metal ions under a pH gradient. The energy for this movement comes from the simultaneous counter transport of protons.
