Thermal Degradation Studies and Kinetic Parameter of Biphenol and Butanediamine
Abstract: The present paper informs the thermal degradation studies of 2, 2? - biphenol - butanediamine - formaldehyde terpolymer. Initially this terpolymer was synthesized from 2, 2? - biphenol, butanediamine with formaldehyde by the polycondensation reaction in the presence of acid catalyst at temperature 150 0C. The terpolymer after purification were characterized by elemental analysis and spectral studies such as UV - Visible, FT - IR and 1H - NMR spectra which were used to confine the most probable structure of synthesized terpolymer. Characterization was carried out by different physicochemical techniques viz. Number average molecular weight determines by Non - aqueous conductometric titration and Intrinsic viscosity by Ubbelohde Viscometer. Non isothermal thermogravimetric technique has been carried out for thermogravimetric study. Freeman - Carroll methods have been applied for the calculation of kinetic parameters. Thermal study of the terpolymer was carried out to determine their mode of decomposition and relative thermal stability by calculating activation energy, order of reaction and frequency factor. By studying above method we concluded that this newly prepared terpolymer is thermally stable at high temperature.
