  • Abstract

    The novel terpolymer resins (2,2-BPTEPAF- I, II, III) have been synthesized by condensation polymerization of 2,2-biphenol (2,2-BP) and tetraethylenepentamine (TEPA) with formaldehyde (F) in presence of 2 M NaOH as a catalyst using varying molar ratios of reacting monomers. The composition of resins has been determined by elemental analysis. Spectral studies such as UV-Visible, FT-IR and 1H NMR spectra have been used to confine the most probable structures of newly synthesized terpolymer resins. Non-isothermal thermogravimetric analysis has been carried out to determine their mode of decomposition and relative thermal stability. Kinetic parameters such as energy of activation (Ea), order of reaction (n) and frequency factor (z) has been calculated by applying Friedman, Chang and Sharp-Wentworth methods. The computed results are compared and elaborated.
