Description :
Terpolymeric material was synthesized by the condensation of 2,6-dihydroxy acetophenone, paraphenylenediamine, and formaldehyde in the presence of acid catalyst with 1:1:2 molar ratio of reacting monomers. The polymer has been characterized by UV–visible, IR and 1H-NMR spectra. Thermal degradation curve has been discussed in order to determine its mode of decomposition, order of reaction, apparent activation energy, frequency factor and free energy change. Freeman-Carroll and Sharp-Wentworth methods have been applied for the calculation of kinetic parameters while the data from the Freeman-Carroll method have been used to determine various thermodynamic parameters. This polymer is also found to possess optimum antibacterial activities.
