Conclusions
-
1.
The authors study the kinetics of formation of polyaziridines when aromatic bisazides react with ethylene glycol dimethacrylate: Δ2-triazolines are formed as an intermediate product, and then lose nitrogen to form aziridines.
-
2.
The rate constants, activation energies, probability factors, and entropies of both stages of the reaction are found. The formation of Δ2-triazolines is a second-order reaction; the transition from Δ2-triazoline to aziridine obeys a first-order reaction and has more than one stage.
