The Terpolymer resin (2N, 1N-4, 4'DADPEF-1) was synthesized by polymerization of monomers 2-Nitroso-1Napthol and 4, 4'Diaminodiphenyl Ether with formaldehyde in 1:1:2 molar proportion. The terpolymer resin was characterized by elemental analysis, spectral studies i.e. UV-Visible, FTIR and NMR spectroscopy. The surface characteristics were examined through scanning electron microscopy (SEM) at different magnifications. The tentative structure of the terpolymer was confirmed on the basis of spectral data. Freeman -Carroll and Sharp-Wentworth methods have been applied for the calculation of kinetic parameters. The thermogravimetric analysis (TGA) was performed to evaluate the thermal degradation characteristics and to ascertain its thermal stability. The residue left over after complete decomposition was found to be negligible (0.90% found and 1.07% calculated).

Terpolymeric resins (2,2′-DHBPBDF) (DHBP = dihydroxybiphenyl; BD = butylenediamine; F = formaldehyde) were synthesized by the condensation of 2,2′-DHBP, 1,4-BD and formaldehyde in the presence of an acid catalyst with varied molar ratios of reacting monomers. Resin composition was determined on the basis of its elemental analyses. Their number-average molecular weight was determined by conductometric titration in non-aqueous media. The viscosity measurements were carried out in N,N-dimethylformamide at room temperature. Ultraviolet–visible, infrared and proton nuclear magnetic resonance spectral studies were undertaken to elucidate the structure of these resins. The thermal stability and kinetics of the thermal decomposition of these newly synthesized resins have been evaluated on the basis of thermogravimetric analysis and differential thermal analysis. The ion-exchange properties of these resins were studied for different metal ions. A batch equilibrium method was employed to study the selectivity of metal ion uptake. The study was carried out over a wide range of pH and ionic strengths of different electrolytes.

Background: Terpolymer having 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 polycondensation method and to evaluate thermal properties of terpolymer. 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 indicates that the thermal decomposition would be a slow reaction. Conclusion: The thermal energy of activation calculated by using Sharp-Wentworth and Freeman-Carroll methods are found to be nearly identical. The terpolymer 8-HQ-5-SAAF starts degradation at high temperature, showing that this polymer resin is thermally stable.
