In recent years, much attention was paid to new energetic binders used in high-energy solid propellants,which were synthesized from ring opening of oxirane and oxetane with different energetic groups. The relationships between the different energetic groups and physical and chemical properties，such as densities,heats of formation,melting point and mechanical properties,were reviewed. Finally, the possibility of this type of energetic binders used in PBX explosives was discussed by comparing their strongpoint and disadvantages.
