The thermal degradation of poly(ether sulfone) (PES) and polysulfone (PSF) was studied with a combination of thermogravimetric analysis and stepwise pyrolysis-gas chromatography/mass spectrometry techniques with consecutive heating of the samples at fixed temperature intervals (100 °C) to achieve na
## Abstract The thermal degradation processes which occur in poly(ether‐sulfone) (PES) and poly(phenylene oxide) (PPO) have been studied by Direct Pyrolysis‐Mass Spectrometry (DPMS). The pyrolysis mass spectra of PES and PPO contain molecular ions up to __m/z__ 700, corresponding to pyrolysis compo
