Studies on Polyazomethine Chelate Polymers

Abstract
Poly-Schiff-base ligand (SBSAL-DDM) is synthesized by condensing bis-salicylaldehyde 5,5′-sulfone with 4,4′-diaminodiphenyl methane. The polychelates of Cu(II), Ni(II), Co(II), and Mn(II) with poly-Schiff base have been isolated and analyzed. The analytical data agree with 1:1 metal-ligand stoichiometry. The polychelates are studied in terms of electrical, thermal, spectral, and magnetic properties. A probable structure has been proposed for the above polymers.
