The thermal degradation of poly[3‐dimethyl (methylmethacryloyl)ammonium propanesulfonate], [poly(DMAPS)], was studied under nitrogen and air atmosphere at various heating rates. The kinetic parameters such as 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 interval (Δ T ), but the weight loss (Δ W ) between the temperature of the start and the end of degradation is approximately independent of the sample weights.
