摘要
用高分辨裂解气相色谱质谱（ＨＲＰｙＧＣＭＳ）研究了聚亚苯基苯并二噻唑、聚亚苯基苯并二唑的热分解行为，鉴定了相应裂解产物的组成、分布及其与高分子结构的关系，并用热重法（ＴＧ）测定了它们的热分解反应动力学参数。
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.\=
