The thermal degradation of poly(pphenylenebenzobisthiazole) (PBZT) and poly-(pphenylenebenzobisoxazole) (PBZO) was studied by high resolution pyrolysis-gas chromatography/mass spectrometry (HR Py-GC/MS) and thermogravimetry (TG).The pyrorgams of PBZT and PBZO were obtained at the pyrolysis temperatures between 764 and 1040
and the pyrolyzates were identified by on-line MS.The influence of pyrolysis temperature on pyrolyzate yields is discussed.The thermal degradation mechanisms of PBZT and PBZO are described based on the results of HR Py-GC/MS and dynamic parameters.
