Non-isothermal Kinetic Study of p-Cresol-Dithiooxamide-Formaldehyde Terpolymer
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....

| Summary: | 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. |
