Amberlite XAD-4 resin was functionalized by coupling it through an –N=N- group with hydroquinone. The resulting intermediate products were characterized by FTIR method. The functionalized resin was characterized by elemental analysis and FTIR. The Thermokinetic parameters were determined by Freeman-Caroll (FC) and Sharp-Wentworth (SW) methods. The activation energies of degradation were found to be 41.61KJ (FC method) and 40.56KJ (SW method). The free energy and entropy of degradation was calculated by both of these methods were found to be in good agreement. The order of degradation obtained by FC method was found to be 0.85 which was further confirmed by SW method.
