Abstract: 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-CH2, in both HX-752 and PISA is different.

Key words: 13C-NMR, Aziridine derivaties
