Polybutadiene crosslinked by 1,3-dipolar cycloaddition: Pyrolysis mechanism, DFT studies and propellant burning rate characteristics

The burn rate of the propellant was evaluated and a lower pressure exponent is exhibited. This could be directly correlated to the thermal decomposition pattern of the cured binder and propellant. This study provides insight for processing energetic solid propellants wherein the basic decomposition mechanism of the new triazole-triazoline crosslinked polybutadiene based propellant binder and ballistics of the solid propellant processed using the new binder.
