Abstract
A terpolymer poly (vanillin-co- furfural-co-4-methylacetophenone) has been prepared by polycondensation technique in the presence of an acid catalyst. The structure of terpolymer has been elucidated on the basis of various physico-chemical techniques like FT-IR, 1H NMR, Pyrolysis (Py) (gas chromatography/mass spectroscopy, GC/MS), nitrogen adsorption/desorption analysis, gel permeation chromatography, thermogravimetry – derivative of thermogravimetry (TG-DTG), and differential scanning calorimetry. The apparent activation energies (E a) of each step (0.1 ⩽ α ⩽ 0.9) during thermal degradation have been determined using Flynn-Wall-Ozawa method. The degradation through random scission and unzipping mechanism is discussed based on the kinetics by nonisothermal kinetics by TG-DTG and products obtained by Py (GC/MS). The type of solid-state mechanism is three-dimensional diffusion.
