Abstract
8-Acryloyloxyquinoline(8-AOQ), prepared from acryloyl chloride and 8-hydroxyquinoline, was polymerized in methyl ethyl ketone at 70°C using benzoyl peroxide as a free radical initiator. Polychelates were obtained when aqueous solution of Th(II)/Cd(II)/Zn(II)/Ni(II) and Mg(II) ions were added to the polymer dissolved in sodium hydroxide solution. The IR spectra of these polychelates suggest that metals are coordinated through oxygen of the esteric carbonyl with nitrogen atom. Elemental analysis of polychelates suggests that the metal-ligand ratio is about 1:2. The electronic spectra, EPR, and magnetic moments of polychelates showed an octachedral and square planar structure for poly(8-AOQ)- Ni(II)/Th(II) and poly(8-AOQ)-Zn(II)/Cd(II)/Mg(II) complexes respectively. X-ray diffraction studies reveal that the polychelates are highly crystalline. The thermal properties of polymer metal complexes are discussed.
