摘要
The process of thermal degradation of sulphonated polyetherketoneketone (SPEKK) was studied by the thermogravimetry (TG) and differential thermal gravinetric analysis (DTG).There were two weight loss steps in TG for SPEKK.The first one was the -SO 3H aparts from the main chain of SPEKK,the activation energy was found to be 67.44kJ/mol.The second,was the polymer main chain degradated of which the activation energy was about 210.4kJ/mol.The thermal degradation of SPEKK was in agreement with the models of random initation.
