The mechanical, sorption, and diffusion properties of films based on interpolyelectrolyte complexes of sodium poly-4,4′-(2,2′-disulfonato)diphenyleneisophthalamide and polymers containing weakly basic amino groups [polyethylenimine, poly-N-(2-aminoethylacrylamide), and poly(2-vinyl-2-imidazoline)] were studied. The influence exerted on the properties of these materials by the electrostatic interaction of the polyelectrolytes, degree of their conversion in the occurring interpolymer reactions, and composition of the interpolyelectrolyte complexes formed was demonstrated. The interpolyelectrolyte complexes have good deformation and strength properties and high ability to selectively take up water relative from its mixtures with ethanol. Specific features of the self-diffusion of water-ethanol mixtures of different composition in the interpolyelectrolyte complex samples were considered. The possibility and conditions of preparing high-performance membranes for hydrophilic pervaporation from these complexes were found. The separation factors for water-ethanol mixtures, estimated from the NMR data, reached approximately 103.improving the processability of the polymeric compound.
