Characterization of diglycidylamine epoxy resins based on bis-hydrazones

A series of hydrazones based viscous epoxy resins having N–N bonds in their backbones have been developed as energetic binders for composite solid propellants. A few typical resins have been characterized by their molecular weight distribution, 13C NMR spectra and glass transition temperature. The gel permeation chromatography studies carried out show the composition profile in the glycidyl amine synthesis. Spectral studies confirm the epoxidation of the hydrazones. The cured dicarboxyl bishydrazone based resins have glass transition temperatures in the range −13 to 55°C
