| Abstract: | 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.= |
