✦ Synopsis

The thermal degradation of poly[3dimethyl (methylmethacryloy1)ammonium propanesulfonate], [poly@MAF'S)], waa studied under nitrogen and air atmosphere at various heating rates. The kinetic parameters such aa activation energy, preexponential factor, and reaction order were determined by Ozawa's method. Thermal degradation of such polymer occurs in two and three stages in nitrogen and air atmosphere, respectively. Larger sample weights produce a larger temperature internal (AT), but the weight l w (A W ) between the temperature of the start and the end of degradation is approximately independent of the sample weights.
