    Calculation of PFA Isothermal Thermal Stability from a DSC Curve of Its Thermal Degradation

      摘要
    • 摘要: 利用一条非等温的ＤＳＣ曲线，从研究ＰＦＡ热降解的最可几反应机制及其活化能入手，推导出在等温条件下反映热稳定性的降解率，温度和时间之间的简单关联式。结合红外光谱对ＰＦＡ热降解过程作初步探讨。

       

      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.
