摘要：
The pyrolysis of a poly( phthalazinone ether sulfone ketone) (PPESK) film in N-2 atmosphere was investigated by thermogravimetric analysis. Results show that the thermal stability of the PPESK film is very high. The thermal degradation of PPESK film is very violent in the temperature range 400 similar to 600 degreesC which is a crucial temperature zone for pyrolytic carbonization. The reaction is first order. The dynamic data analyzed using the Kissinger peak maximum technique give an apparent global activation energy, E of 211.35 kJ/mol. When the isoconversion procedure developed by Ozawa is used, E is increased from 152.31 kJ/mol to 274.43 kJ/mol with an increase of the conversion from 10 % to 30 % and the frequency factor LnA is increased from 21.98 to 38.75 min(-1).
