Abstract

Thermal Applications of p-Cresol-Oxamide-Formaldehyde Terpolymer Resin-III

Terpolymer resin p-COF-III was synthesized by the condensation of p-Cresol (p-C) and oxamide (O) with formaldehyde (F) in the presence of 2M HCl as catalyst with 3:1:4 molar ratios of reacting monomers. The resin was characterized by elemental IR and NMR spectra, the morphology was studied by SEM. Thermal study of the resin was carried out to determine its mode of decomposition and relative thermal stability. The Freeman-Carroll and Sharp- Wentworth methods have been used in the present investigation to calculate thermal activation energy and different kinetic parameter of the terpolymer resins, like frequency factor (Z), entropy change (DS), free energy change (DF) and apparent entropy (S*) have been determined using Freeman-Carroll method.
