dc.description.abstractOligo{2,20-{1,4-phenylenebis[nitrilomethylylidene]} bis(6-methoxyphenol)} (OPNMMP) was synthesized from o-vanillin and p-phenylene diamine by oxidative polycondensation with NaOCl in an aqueous alkaline. Then, a new Schiff Base epoxy oligomer resin, OPNMMP-epichlorohydrine (EPC), was produced with EPC. The structures of the resulting compounds were confirmed by Fourier transform infrared spectroscopy, ultraviolet-visible spectroscopy, H-1-NMR, and C-13-NMR. Further characterization processes were preformed by thermogravimetry (TG)-differential thermal analysis, gel permeation chromatography, and solubility testing. Also, the kinetics of the thermal decomposition of OPNMMP-EPC were investigated by thermogravimetric analysis. The TG curves showed that the thermal decomposition of OPNMMP-EPC occurred in one stage. The kinetic parameters related to the decomposition kinetics of OPNMMP-EPC were obtained from TG curves with the following methods: Friedman, Flynn-Wall-Ozawa, Kissinger, invariant kinetic parameter, and Coats-Redfern (CR), under an N-2 dynamic atmosphere and different heating rates (5, 10, 15, and 20 degrees C/min). The mechanism function and pre-exponential factor were also determined by a master plots method. The apparent activation energies of the thermal decomposition were calculated from these methods for OPNMMP-EPC. The analysis of the results obtained by the CR and master plots methods showed that the decomposition mechanism of OPNMMP-EPC in N-2 was a deceleration-type mechanism.
