Preparation and Characterization of Poly Metal Complexes Derived from 5,5'-Methylenebis(2-Hydroxy Benzaldehyde) and 6,6'-Methylenebis(2-hydroxy naphthaldehyde) with Hydrazine and 4-Amino Phenyl Ether

摘要

Some new Schiff base polymers were prepared by polycondensation of 5,5'-methylenebis(2-hydroxy benzaldehyde) and 6,6'-methylenebis(2-hydroxy naphthaldehyde) with 4-aminophenyl ether and hydrazine in acidic media. After polymerization, Schiff base polymers were treated with Cu and Ni acetate to prepare poly metal chelates by solution technique. The poly metal chelates were characterized by elemental micro-analysis, IR, UV-visible and spectroscopic techniques. The solutions of poly metal chelates were prepared in THF at 30 °C, to investigate viseometric study by dilute solution viscometry (DSV) method. The intrinsic viscosities of these poly metal complexes were ranged within 0.393-0.5201 dL/g as compared to 0.174-0.249 dL/g for Schiff base polymers in THF. Thermoanalytical studies of poly metal complexes were examined and compared.
