Thermal stability of poly(2‐acrylamido‐2‐methylpropanesulphonic acid) and polymer complexes of 2‐acrylamido‐2‐methylpropanesulphonic acid with some transition metal salts

Abstract Poly(2‐acrylamido‐2‐methylpropanesulphonic acid) and polymer complexes of 2‐acrylamido‐2‐methylpropanesulphonic acid with nickel(II), copper(II), iron(III) chlorides and cobalt (II) sulphate, respectively, were prepared and characterized by spectroscopic techniques. Thermal stability of the formed polymer complexes was determined by means of thermogravimetric analysis. It was found that the thermal stability of the homopolymer is less than that of the polymer complexes. The activation energies of the degradation of the polymer complexes were determined by using the Arrhenius equation.
