【Abstract】 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.更多还原
