利用裂解色谱-质谱对4个同一系列新型咔哚聚芳醚砜样品的裂解规律进行了研究,分别得到了各自链节的裂解特征碎片,证明了各聚合物确实发生了缩聚反应. The cleavage patterns of four novel carbazole polyarylethersulfones were investigated by pyrolysis chromatography-mass spectrometry. The fragmentation characteristics of the respective chain segments were obtained respectively, and it was proved that the polycondensation reactions did occur in all the polymers.
