| Abstract: | The process of thermal degradation of polyetherketoneketone(PEKK) was studied by thermogravimetry analysis (TG) and differential thermal gravimetric analysis (DTG). The activation energy for thermal degradation of PEKK was found to be 204KJ/mol,the reaction rate is first order. The results indicated that both the PEKK has ex cellent thermal stability and thermal degradation of PEKK were in agreement with the models of iandon initiation. |
