Copolymerization of 3,3‐bis (nitratomethyl) oxetane and 3‐azidomethyl‐3‐methyloxetane was carried out in the presence of the triisobutyl‐aluminum‐water catalyst system. The structure of synthesized high‐molecular copolymers was proven with 13 C and 1 H NMR, IR‐Fourier spectroscopy, GPC, and elemental analysis. The data on relaxation and phase transitions as well as the thermal decomposition of copolymers were obtained using the DSC method.
