Polyethylene glycol dinitrates (PEGN) with molecular weights between 400 and 20 000 gźmol-1 were prepared from polyethylene glycols by esterifcation with nitric acid/sulfuric acid in dichloromethane. The products were characterized by gel permeation chromatography. The yield of PEGN increases with increasing reaction temperature (0-40 °C) however large liberation of nitrogen oxides was observed at 40 °C. No infuence of reaction temperature (0-40 °C) on the cleavage of the polyethylene glycol chain during esterifcation was observed. The dependence of melting point on the molecular weight of PEGN was determined. Polyethylene glycol dinitrates with molecular weights Mn above 454 are not sensitive to impact. Heat of combustion of PEGN increases with increasing molecular weight. All samples tested decompose in a similar way during thermal exposition.
