Synthesis and Non-Isothermal Degradation Studies of Biphenol and Hexamethylenediamine
Abstract: Polycondensation reaction was employed to synthesize the new 2,2?-BPHMDAF terpolymer from the monomers namely 2,2?-Biphenol (2,2?-BP), Hexamethylenediamine (HMDA) with Formaldehyde (F) in presence of 2M HCl as a catalyst using 1:1:2 molar ratios at temperature 150 0C. The terpolymer after purification was characterized by elemental analysis and spectral studies such as UV-Visible, FT-IR and 1H-NMR spectra which were used to elucidate and confirmed the most probable structure of synthesized terpolymer. The synthesized terpolymer was then further characterized by different physicochemical techniques viz. Number average molecular weight determines by Non-aqueous Conductometric titration and Intrinsic viscosity by Ubbelohde Viscometer. The thermogravimetric study of the prepared terpolymer has been carried out by non isothermal thermogravimetry technique in which sample is subjected to condition of continuous increase in temperature at linear rate. 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. Freeman-Carroll method?s activation energy was further used to determine the thermodynamic parameters such as entropy change, free energy change and apparent entropy change. 2,2?-BPHMDAF terpolymer was synthesized to determine its thermal stability and which were proved to be thermally stable by studying above methods.
