Abstract
Terpolymer (p‐CDF) has been prepared by using the monomer p‐cresol, dithiooxanude and formaldehyde in 1:1:2 molar proportions. The structure of p‐CDF terpolymer has been elucidated on the basis of elemental analysis and various physicochemical technique like UV‐visible, FTIR, 1H NMR and TG analysis. Detailed thermal degradation curve is discussed which shows four steps decomposition. The activation energy (Ea) and thermal stability calculated by using the Sharp Wentworth, Frceman‐Carroll methods. Thermodynamics parameters such as entropy change (ΔS), apparent entropy change (S*) and frequency factor (z) have also been evaluated on the basis of the data of Freeman‐Carroll method. The order of reaction (n) is found to be 1.05.
