Investigation of Composite Propellant Based on Hydroxyl Terminated Polybutadiene–1-Chloro-2,4-Dinitrobenzene

When attaching 1-chloro-2,4-dinitrobenzene in the hydroxyl terminated polybutadiene backbone, a new energetic prepolymer will be formed without destroying the physicochemical properties, fluidity, and microstructure of hydroxyl terminated polybutadiene. This paper discusses a new composite propellant based on hydroxyl terminated polybutadiene–1-chloro-2,4-dinitrobenzene binder. This solid propellant has been formulated and characterized. The results have shown a 35% increase in burning rate and density. In addition, they exhibited good mechanical and rheological properties over a wide range of temperatures (similar to hydroxyl terminated polybutadiene propellant). Based on the experiments carried out, this prepolymer seems promising as an energetic binder to increase the density-specific impulse for solid propellants and to substitute for both hydroxyl terminated polybutadiene and for recent energetic binders.
