Monolithic nitrocellulose-cellulose composites were prepared by separately cross-linking the mixed precursors (NC + C) with hexamethylene diisocyanate (HDI). The syntheses were optimised according to the component mass ratios, HDI, solvent and catalyst concentration. The concentrations of the reactants and cure catalyst are the most important factors. The general method of synthesis involved dissolving HDI and the catalyst in methylene chloride and then wetting an NC-C mixture with the solution. The resulting mixture was placed in a sealed box for cross-linking at room temperature. Finally the solvent was evaporated at ca. 40 C. The NC-C composites obtained were characterized using TG/DTA and sensitivity to friction and drop weight impact, and were used as energetic materials in reactive armour elements.
