| Abstract: | Non-isothermal thermogravimetry was used to study the decomposition kinetics of poly（phenylene oxide）（PPO）.The activation energy（Ea） was calculated.Integral method with 36 types of kinetic function was proposed to define the most probable kinetic function.The decomposition kinetic parameters are determined,the most probable kinetic function is gained,the Ea is 211.64 kJ/mol,the pre-exponential（A） is 6.24×107 s-1, and the corresponding thermal decomposition dynamic function is gained. |
