发明名称 One-pot process for making multifunctional tetrazole polyols to produce tetrazole based polymers
摘要 A process for making energetic urethane cured binders by making poly-tetrazoles to produce multi-functional tetrazole polyols for producing tetrazole base polymers. Embodiments of the present invention relate generally to a process for preparation of a monomer including reacting an effective amount of nitrile(s) with inorganic azide and a divalent zinc salt in a first solvent, cooling to room temperature producing poly tetrazole purifying the poly tetrazole by recrystallization or precipitation in a second solvent, and reacting an effective amount of the purified poly-tetrazole with a third solvent, a soluble reversible or non-reversible base, and 2-chloro-ethanol, cooling to room temperature producing tetrazole polyol. Embodiments of the present invention further include the monomers produced by the processes described herein.
