摘要
用高分辩裂解色谱-质谱法研究聚芳醚醚酮的热分解,分离和鉴定了热分解产物,考察其组成分布及温度依赖性。结合热重数据和热分解动力学模型分析,进而讨论了聚芳醚醚酮的热分解机理。
The thermal degradation of poly(aryl ether ether ketone)was studied byhigh resolution pyrolysis gas chromatography-mass spectrometry technique in this work.The composition identification,distribution and temperature dependence of the pyrolysateswere inspected as the information regarding the thermal degradation behaviour.Com-bining the kinetic model analysis based on TG data,finally,the thermal degradation mech-anism of PEEK was discussed.
