Poly(N-isopropylacrylamide), PNIPAM, and copolymers of N-isopropylacrylamide and di(ethylene glycol)methyl etber methacrylate, P(NIPAM-co-DEGMEM), grafted on the polypropylene membranes exhibited excellent conformational responses to temperature changes. Membranes were impermeable for aqueous solution at room temperature while at 43 °C the flux reached 0.048-0.061 cm3/cm2min at 0.02 MPa. Permeation of LiCl and NaCl was tested in dialytical process. The best results for LiCl and NaCl fluxes were obtained at room temperature. Probably, at this temperature DEGMEM units facilitated the ions transport. It is expected that ethylene glycol units created structure of channels for lithium and sodium ions.
