Abstract
Thermo Gravimetric Analysis (TGA) analysis was employed to investigate activation
energy (Ea) for the process of degrading of poly(o-toluidine) (POT) applying Horwitz & Metzger,
Coats & Redfern and Chan et al., methods. POT was synthesized by chemical oxidative
polymerization method using Ammonium per Sulphate (APS) as an oxidant while Dodecylbenzene
Sulphonic Acid (DBSA) and sulfuric acid as co-dopants. Different samples, synthesized by
variations in the reactions parameters, were evaluated in order to choose the one with the highest
activation energy of degradation. Additional characterization of the polymer was carried out
through different techniques such as Scanning Electron Microscopy (SEM), UltraViolet Visible
spectroscopy (UV-Vis) and X-Ray Diffraction (XRD) analysis.
