Abstract:

This invention relates to alcohols and more particularly to energetic polynitroakyldiols. The chief promise of energetic polynitrodiols for practical explosive applications are as monomers for the synthesis of hydroxy termined prepolymers. In practice, the prepolymers are mixed with solid explosive, HOCH2...CH2OH X2R yields HOCH2...CH2ORO-CH2...CH2nOH ex., RDX or HMX, an energetic plasticizer and isocyanate curing agents. The liquid slurry is then cast into a suitable mold and cured to form a rubbery matrix which not only binds the solid explosive and defines the shape, but also contributes energy to the final composition. An object of this invention is to provide new polynitrodiols which are useful as components of energetic polymers. A further object of this invention is to provide new polynitrodiols which are stable to deformylation loss of formaldehyde. Yet another object of this invention is to provide new branched chain polynitrodiols which can improve the hydrolytic stability of energetic polymers such as polyesters. A still further object of this invention is to provide a method of preparing these new energetic polynitrodiols. These and other objects of this invention are achieved by providing branched polynitrodiols.
