Non-isothermal decomposition study of copolymer derived from 2-amino 6-nitrobenzothiazole, melamine, and formaldehyde

Abstract

2-Amino 6-nitrobenzohiazole, melamine, and formaldehyde were utilized as a monomer in 2:1:4 M proportions to form BMF-II copolymer using polycondensation polymerization technique in presence of 2 M HCl as catalyst. In light of the essential assessment and spectrical technique like UV–Visible, FT-IR, and 1H NMR spectroscopy, the construction of the integrated copolymer not really set in stone. A non-aqueous conductometric titration approach were used to evaluate the copolymer's number average molecular weight. The surface morphology of a copolymer was concentrated on utilizing scanning electron microscopy. The The energy of activation have been evaluated from thermal methods. The four disintegration steps of the warm crumbling bend are inspected. Utilizing the Sharp-Wentworth, and Freeman-Carroll techniques the activation energy (Ea) and thermodynamic parameters were assessed. based on information from the Freeman-Carroll technique, kinetic and order of reaction, for example, entropy change (ΔS), free energy change (ΔF), evident entropy change (S*) and recurrence factor (Z) were additionally assessed. The Activation energy calculated by these methods are good in agreement with each other. It is found that the order of reaction (n) is 1.16.
