Hydroxyl-terminated triblock copolymer poly(glycidyl nitrate-block-butadiene-block-glycidylnitrate) an energetic binder was synthesized by ring opening polymerization of glycidylnitrate in the presence of hydroxyl-terminated poly(butadiene)catalyzed by BF3 · OEt2. The different conditions of synthesis were used to improve the molecular weight and mechanical properties of binder. The resulted triblock copolymer was characterized by FTIR, 1H NMR, GPC and DSC. According to DSC, the glass transition temperature of synthesized block polymer is –27°C, which is suitable for use as an energetic propellant binder.
