| Abstract: |
| The kinetics of thermal degradation of NR/BR vulcanizate in the range from room temperature to 500℃ was studied with TG .The activation energy and the reaction order at two degradation stages were obtained with Coats-Redfern method.The relationship between k(reaction rate constant) and T(temperature) was obtained through the calculation of the apparent activation energy and the frequency factor of the blend degradated in different degrees with Doyle method.The oxidation activation energy was calculated with Fuoss Formula. |
