Telechelic poly(vinyl alcohol) was condensed with phenyl hydrazine and malononitrile in a basic medium to give hydrazone and pyran derivatives, respectively. In further studies, poly(vinyl alcohol) (PVA) was reacted with chloroacetonitrile, biuret, thiophene carbonyl chloride, acrylonitrile, and phenyl isothiocyanate to give modified polymeric materials. An addition product of acrylonitrile was treated with hydroxylamine hydrochloride to give the amidoxime derivative. The prepared amidoxime and carbamate ester of polymeric material were complexed with CuCl 2 solution. The complexation was confirmed by UV and EDS measurements. The morphology of PVA and copper (II) complex of amidoximated-PVA was studied by SEM. Biological activity of some of the prepared compounds was investigated against bacterial and fungal microorganisms. [ABSTRACT FROM AUTHOR] |
