Terpolymer resin (4-ASAOF-III) has been synthesized by the condensation polymerization of 4-Aminosalicylic acid (4-ASA) and Oxamide (O) with Formaldehyde (F) in the presence of 2M HCl as a catalyst using 3:1:4 molar ratios of reacting monomers. The empirical formula and empirical weight of the resin were determined by elemental analysis. The structure of the resin was characterized by various spectral techniques like infra-red (FTIR) and nuclear magnetic resonance (1H and 13C-NMR) spectroscopy. The morphological feature of the 4-ASAOF-III terpolymer resin was established by Scanning electron microscopy (SEM). Thermal study of the resin was carried out to determine its mode of decomposition and relative thermal stability. The Freeman–Carroll, Sharp Wentworth, Friedman and Change technique have been used in the present investigation to calculate thermal activation energy (Ea), order of reaction (n) and frequency factor (z).
