Synthesis and Characterization of Poly(etherdiphenylene terephthalamide)-Metal Complexes in Heterogeneous Medium
Abstract: Condensation of terephthalic acid and 4,4ʹ-diaminodiphenyl ether resulted in aminoterminated oligomeric poly(etherdiphenylene terephthalamide) (PODTA) using phosphorylation technique. Schiff base complexes of this polyamide were synthesized with salicylaldehyde and 2-hydroxy-1-naphthaldehyde complexes of Co(II),Ni(II) and Cu(II). All the synthesized polyamide as well as Schiff’s base complexes were characterized by elemental analysis, IR spectroscopy and magnetic susceptibility measurements. Thermal stabilities of ligand and its various complexes were compared by thermogravimetric analysis. While, Co(II) …
