## 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
## Abstract The mechanisms of thermal degradation of poly(ether‐ketone) (PEK) and four poly(ether‐ketone)/poly(ether‐sulfone) copolymers (PEK/PES) have been investigated by direct pyrolysis‐mass spectrometry (DPMS). Several families of pyrolysis compounds with H, OH and CHO end‐groups have been ide
