摘要：
Thermogravimetric studies of the sodium salt of poly(acrylic acid), its modified sodium salt and its various metal complexes were made. The thermal stabilities of the various systems decreased in the order: poly(acrylic acid)>Ni(II) > Co(II)> Zn(II)> Fe(III)> Cu(II)> polymeric sodium salt. The higher thermal stabilities of the polymer-metal complexes result from the development of stable ring structures in.,the polymer matrix upon coordination with metal ions. The metal-ion complexation of carboxylate ligands of linear poly(acrylic acid), optimization of the complexation conditions and infra-red and ultraviolet-visible spectrometric characterizations are also illustrated.
