Glycidyl azide polymer (GAP) is a unique elastomeric binder with high heat of formation and high density due to enhanced thermal and performance properties of composite solid propellants. However, GAP has high glass transition temperature and poor mechanical properties that are limited its application as a binder in a composite solid propellant. In this paper , the efforts carried out on modification of mechanical properties and glass transition temperature of polyurethane based on GAP through preparing copolymer based on GAP using flexible back bone such as Polyethylene glycol (PEG), Polycaprolactone (PCP) and Hydroxyl terminated polybutadiene (HTPB) was reviewed and the results were investigated.
