Abstract
Sorption, transport, and mechanical properties of chitosan-poly(acryli c acid) interpolyelectrolyte complexes of various compositions were st udied. It was found that these complexes are stable in aqueous solutio ns at pH 5 - 8 and show high dialysis permeability to law-molecular-ma ss water-soluble compounds. Their permeability is comparable to that o f commercial hydocellulose membrane Diacell, which is presently used i n medicine. The rather high mechanical properties of the films of chit osan-poly(acrylic acid) interpolyelectrolyte complexes, combined with the high transport properties, make it possible to use these. films as separation membranes, particularly, far pervaporation separation of o rganic aqueous mixtures.
