The resin-I (abbreviated as PTSMF-II) was synthesized by polycondensation reaction of p-toluensulfonic acid (0.05M), m-cresol (0.1M) and formaldehyde (0.2M), in presence of an acid catalyst (1M HCl). The structure of resin was determined by its elemental analysis, UV-VIS, IR data. Non-aqueous conductometric titration technique was employed to determine the molecular weight of the terpolymer. In the present paper investigation of the thermokinetic parameters such as apparent entropy (ΔS), frequency factors (A), free energy change (ΔG). The order of degradation reaction determined by Freeman Carroll (FC) and Sharp Wentworth (SW) methods.
