Hydroxy-terminated polybutadiene is widely studied and most used prepolymer for binder system of composite solid propellants, but it brings down the overall energy because of its inert nature. Polybutadienes containing triazole (PBT) overcome this limitation by introducing energetic groups into PB, so they can act as energetic binder. Furthermore, it is noteworthy that pendant functional group connected to triazole can be applied to further transformation of PBT. We prepared several phenyl-terminated polybutadienes (PtPBs) containing various triazoles via click reaction between azidated PtPB and alkyne derivatives. All of azide groups in polymer converted to triazolyl groups completely with high yield, and products were confirmed by NMR, IR, GPC and DSC.
