Abstract Nanostructurized polyurethanes of different structure and functionality were obtained and used for studying silver ions adsorption from aqueous medium. Formation of (Ag+)n-polymer complexes was confirmed by combination of UV-vis/FTIR spectroscopy. Silver ions capacity of polyurethanes obtained reaches 1.1-1.4•10-5 mol/g for polymers based on polyester (polyether), aromatic diisocyanate and aminefunctionalized chain extender (cross-linker). Presence of urea fragments in polymer macrochains increase Ag+ adsorption capacity of polyurethanes as well.
