A new polymer containing cyano groups was synthesized by ?-irradiation. The amidoximated polymer was prepared using hydroxylamine hydrochloride in basic medium. The characterization of monomer, polymer and amidoximation was confirmed by IR and NMR spectroscopy. The complex formation of the amidoxime salt towards Ag I , Cu II and Ag I /Cu II mixture in aqueous solution was studied by AAS, EDS, and ESR spectrometry. The binding capacity of these metal ions is selective in favor of silver(I) ion. The thermal stability of polymers and their complexes was investigated using TG analysis. The change in their morphology was observed by SEM. Potential biological activity of the polymer and its complexes towards some types of bacteria and fungi was tested under the same conditions. Silver (I) complexed polymer had a strong biocidal activity for all tested bacteria and fungi. [ABSTRACT FROM AUTHOR]
