Abstract
Nylon-6,6 oligomer was prepared from hexamethylenediamine and adipic acid using the conventional phosphorylation technique. The amino terminated oligomer was then converted into Schiff base coordination polymers by interacting it with Co(II), Ni(II) and Cu(II) complexes of salicylaldehyde, [M(SAL)2] and 2-hydroxyl-1-naphthaldehyde, [M(NAPHTHAL)2]. The resulting coordination polymers were characterized by ir spectrescopy, elemental analyses, magnetic susceptibility measurements and thermogravimetric analysis (TGA). Thermogravimetric analysis shows that the coordination polymers were thermally more stable than the oligomer. On the basis of physio-chemical studies a probable structure of the coordination polymers has been proposed.
