Thermal Degradation Studies of High-Performance Copolymer Resin Derived From 8-Hydroxyquinoline, Acrylamide and Furfural

Abstract

Using the polycondensation process with acid medium as the catalyst, the monomers 8-hydroxyquinoline, acrylamide, and furfural were combined to form the copolymer 8-HQAF in a molar ratio of 1:1:2. Elemental analysis method were used to evaluate the molecular weight and composition of the organic copolymer. The structure was clarified through analysis of the FTIR, proton nuclear magnetic resonance (¹H NMR), and UV-visible spectra. SEM analysis was done on the copolymer's crystalline behaviour and surface characteristics (SEM). For the purpose of determining their method of disintegration and relative thermal stability, non-isothermal thermogravimetric analysis The Sharp-Wentworth (SW) and Freeman-Carroll (FC) approaches have been used to compute activation energy, frequency factor, and order of response. Both the Sharp-Wentworth and Freeman-Carroll approaches for calculating activation energy agree with one another.
