Unsaturated Polymides From β(2-Ethoxy-5-methylphenyl) Glutaconic Acid and Their Characterization

Abstract

Someunsaturated polyamide resins were synthesized by condensing @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 decomposi in the range of -190 to 6OO0C. 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 acti~ration of polycondensates depends upon the presence cf diamine components in the polymer.
