Abstract:

Background: Terpolymer have versatile applications in adhesives, electroluminescent devices, packaging, coating materials, ion exchanger and hardener for epoxy resin.

Objective: In the present investigation, our main aim was to synthesize terpolymer using 8- hydroxyquinoline-5-sulphonic acid, anthranilic acid and formaldehyde (8-HQ-5-SAAF) via the polycondensation method and to evaluate thermal properties of terpolymer.

Materials and Methods: 8-Hydroxyquinoline-5-sulphonic acid, anthranilic acid and formaldehyde were used for synthesis. Terpolymer was obtained by employing the polycondensation method.

Results: TGA analysis shows that the synthesized terpolymer resin was thermally stable. The activation energy calculated by Freeman-Carroll and Sharp-Wentworth methods has been found to be in good agreement with each other. The low value of frequency factor and negative entropy value indicate that the thermal decomposition would be a slow reaction.

Conclusion: The thermal energy of activation calculated by using Sharp-Wentworth and Freeman- Carroll methods has been found to be nearly identical. The terpolymer 8-HQ-5-SAAF starts degradation at high temperature, showing that this polymer resin is thermally stable.

Keywords: 8-hydroxyquinoline-5-sulphonic acid, anthranilic acid, morphology, spectral study, terpolymer, thermal analysis.
