摘要 采用高分辨裂解气相色谱 -质谱 (HRPyGC -MS)研究了在不同裂解温度下氰酸酯树脂裂解产物分布以及主要裂解物的产率与裂解温度的关系 ,根据热分解产物的组成及其温度依赖性 ,讨论了氰酸酯树脂的热分解机理。 The thermal degradation of bisphenol a dicyanate resin(CR)was investigated by high-resolu- tion pyrolytic gas chromatography-mass spectrometry(HRPyGC-MS).The pyrolytic products of CR at temperatures ranging from500℃to1040℃were identified.The relation between pyrolyzate yields and pyrolytic temperatures was established.On the basis of the pyrolyzate profile and the dependence of py- rolyzate yields on pyrolysis temperature,the thermal degradation mechanism of CR was proposed.
