Abstract: The stability toward oxidation and chlorine attack for membranes based on the sulfonated crosslinked polyether condensates or co-condensates from furfuryl alcohol and tris(2-hydroxy-ethyl)isocyanurate was studied by means of internal reflection IR spectroscopy. The mechanisms of their oxidation and chlorinolysis have beon discussed.

Key words: furfuryl alcohol resin, reverse osmosis membrane, ATR spectra
