Abstract: Glycerol is nitrated with at least one nitrating source in a solvent to form a nitrated glycerol solution containing dinitroglycerin. The nitrated glycerol solution is treated with at least one cyclizing agent to convert the dinitroglycerin into glycidyl nitrate, which is polymerized into poly(glycidyl nitrate) (PGN). Distillation or other vaporization techniques are not required to remove nitroglycerin from the glycidyl nitrate prior to polymerization of the glycidyl nitrate. Rather, the nitroglycerin can be carried along with the dinitroglycerin during polymerization. As a consequence, the glycidyl nitrate is not exposed to elevated temperatures sufficient to cause accidental explosion or deflagration of the nitrate ester. Still more preferably, the glycidyl nitrate is not heated above room temperature at any time prior to polymerization. Moreover, given the high energy performance of nitroglycerin, the nitroglycerin can optionally be retained with the PGN, i.e.

Abstract: Polyethers containing pendant azide groups are cured without a catalyst by yclo-addition with diacetylenes to form triazole cross-linked, energetic binders having improved mechanical properties and stability. The polyethers typically have three hydroxy-terminated chains each of about 5000 to about 50,000 daltons. Ideally, only one azide group per chain reacts by cyclo-addition since the diacetylene is added in a proportion of about one molecule to each two polyether chains. Repeating units of glycidal azide, azidomethylmethyloxetane, bis-azidomethyloxetane/nitratomethylmethyloxetane, and bis-azidomethyloxetane/azidomethylmethyloxetane are believed effective as polyethers when used with the diethynlbenzenes 1,4-bis(ethynl)benzene, 1,4-bis(ethynlcarbonyl)benzene, and 1,3-bis(cyanoethynl)benzene. The polyethers may be further cross-liked at the hydroxyl terminations by urethane bonds.
