Poly 2-vinylpyridine and its homogeneous composites wing different alkali metal salts were synthesized and charaterized by molecular weight determination, infrared spectroscopy, scanning electron micrography and thermogravimetry. Pyrolysis studies by TG, DTG and DTA under ambient condition of static air or argon suggest decomposition of the polymer and composites in more than one step. Kinetic parameters i.e., order of reaction, rate of thermal decomposition of reaction and energy of activation were evaluated from TG isotherm using Horowitz and Redfarn methods. It was found that the pair of composites having the same anions follows the same thermal and kinetic stability order.
