Abstract

Abstract Some unsaturated polyamide resins were synthesized by condensing β(2-ethoxy-5-methylphenyl) glutaconic acid with six diamines. The polycondensates were characterized by IR. TG, DSC: VPO and elemental analysis. Most of the polymers were found to decompose in the range of ∼ 190 to 600°C. They are brownblack in nature. The kinetics of decomposition was studied. The kinetic parameters were evaluated by the method of Broido. It was observed that the energy of activation of polycondensates depends upon the presence of diamine components in the polymer.
