Abstract
The mechanism and kinetic parameters of the non isothermal thermal degradation of PFA were studied by a differential scanning calorimetry (DSC) curve and infrared spectra.According to the results of alternation of non isothermal degradation with isothermal degradation the simple equation of the relationship between fraction degraded,time and temperature under the isothermal condition is introduced.
