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 pyrolysis of poly (aryl ether ether ketone) was studied by high resolution pyrolysis chromatography - mass spectrometry. The thermal decomposition products were isolated and identified. Their composition distribution and temperature dependence were investigated. Combined with the thermogravimetry data and thermal decomposition kinetic model analysis, the thermal decomposition mechanism of poly (aryl ether ether ketone) was discussed.
