The application of GAP in energetic thermoplastic elastomers(ETPE), energetic plasticizers and energetic curing agent were reviewed. A view was given on the modification of GAP by co-polymerization, end-capping and use special initiator method. The thermoplastic elastomers based on GAP, the copolymers of GAP, ester group or alkyl group terminal, azide group terminal GAP plasticizers and high molecular GAP has excellent application foreground.
