The thermal degradation behavior of polyether sulfone was examined using a dynamic heating program thermogravimetry analyzer under nitrogen atmosphere. The kinetic model of thermal degradation for the polyether sulfone was evaluated by using the kinetic parameters from dynamic thermogravimetric data. A discussion of the applicability of the model is presented using the four consecutive reactions analytical method. The model proposed correlates the thermograms obtained at thermogravimetric and differential thermogravimetric data with the same set of kinetic parameters. The degrees of decomposition for various components of polyether sulfone under dynamic conditions were simultaneously predicted via mathematical simulation. Moreover, the isothermal condition and the degree of decomposition were also predicted for various temperature conditions of the thermal degradation of polyether sulfone.
