摘要
用薄层层析法定性检测出硝酸酯基聚醒聚氨酯老化降解产物中的胺，推断降解机理为氨基甲酸酯中C—N键的断裂，讨论了影响检测的各种因素。
The amine in ageing degradation resultants of nitrate- polyether - based polyurethane was qualitatively determined by thin-layer chromatography. It refers from the results that the occurrence of degradation is due to broken C-N bond. The factors affecting determination were discussed.
