Opis:: Triblock copolymer polyNIMMO-HTPB-polyNIMMO was synthesized by cationic ring opening polymerization of NIMMO (3-nitratomethyl-3-methyloxetane) in the presence of hydroxyl-terminated polybutadiene catalyzed by BF3·OEt2. The polymer was characterized by FT-IR, 1H NMR, 13C NMR spectroscopy, and GPC. DSC was used to investigate the thermal behaviour of the triblock copolymer and its exothermic decomposition peak was found to be at 215 °C. All of the results indicated that the triblock copolymer polyNIMMO-HTPB-polyNIMMO might serve as a potential energetic propellant binder.

Opis:: Glycidyl azide polymers (GAPs), containing different initiating diol units were prepared by treating the corresponding poly(epichlorohydrins) (PECHs) with sodium azide under microwave irradiation (600 W power) at 80 °C, during 12 min. The PECHs containing different diol units were synthesized by the polymerization of epichlorohydrin using borontrifluoride etherate as initiator in the presence of small amounts of low molecular weight diols. The synthesized PECHs and GAPs, containing different initiating diol units, were characterized by various spectroscopic techniques and by thermal analysis (DSC). These results are reported and discussed.
