Synthesis and characterization of metal-containing coordination polymers of poly(methylene diphenylene terephthalamide)

Amino group‐terminated poly(methylene diphenylene terephthalamide) (PMDTA) was prepared using a phosphorylation technique that was then converted into Schiff's base coordination polymers by their reaction with Co(II), Ni(II), and Cu(II) complexes of salicylaldehyde [M(SAL)2] and 2‐hydroxy‐1‐nap...

Description
Summary:Amino group‐terminated poly(methylene diphenylene terephthalamide) (PMDTA) was prepared using a phosphorylation technique that was then converted into Schiff's base coordination polymers by their reaction with Co(II), Ni(II), and Cu(II) complexes of salicylaldehyde [M(SAL)2] and 2‐hydroxy‐1‐naphthaldehyde [M (NAPTHAL)2]. The resulting coordination polymers were characterized by IR, elemental analysis, magnetic susceptibility measurements, and thermogravimetric analysis (TGA). TGA shows that coordination polymers are more thermally stable than is the ligand under similar conditions. On the basis of observed results, an oxygen‐and nitrogen‐coordinated structure for polyar‐amid‐metal complexes has been proposed. © 1993 John Wiley & Sons, Inc.
