Glycidyl azide polymer (GAP) polyurethanes were synthesized by one step reaction. The results of DSC, DTA and static mechanical measurements, show that the GAP binder has a good miscibility with nitrate ester 1, 2, 4-butanetriol trinitrate (BTTN) and its decomposition peak temperature decreases with increasing the concentration of the plasticizer. The elastomeric modulus and the stress of the crosslinked polyurethane gumstocks increase with increasing the content of the crosslinking agent, while the elongation acts oppositely. The relatively small interfacial interaction between solid filler HMX and the GAP binder gives a sharp decrease of the stress and the elongation of the GAP propellants.
