摘要
本文用^(13)C-NMR方法研究了间苯二甲酰二(2-甲基氮丙啶)和癸二酰二(2-甲基氮丙啶)的稳定性和固化反应机理。在常温下,这两种化合物均可缓慢重排为(口恶)唑啉,也可同空气中水发生水解反应。在重排和固化反应过程中,它们的N-CH和N-CH_2键断裂情况是不同的。
The stabilities and curing reaction mechanism of 1, 1 -isophthaloyl bis (2 -methylaziridine) ( HX-752) and decanedioyl bis ( 2 -methylaziridine) ( PISA) were studied by 13C-NMR. HX-752 and PISA can slowly rearrange into oxazolines, and react with water in air at room temperature, respectively.
In the processes of rearrangement and curing reaction, the bond break of N-CH and N-CH, in both HX-752 and PISA is different.
