Thermoplastic polyurethanes (TPUs) is a linear segmented block copolymer composed of soft segment and hard segment. These polymers are distinguished by excellent mechanical properties as well as a wide spectrum of properties, depending on the nature of the starting materials. In this study, we synthesized energetic polyurethanes for propellants and explosives. Polytetramethylene ether glycol (PTMG) and glycidyl azide polyol (gap) as soft segments and 4,4’-diphenylmethane diisocyanate and chain extender as hard segments were used. Differential scanning calorimetry (DSC) and Dynamic mechanical analyzer (DMA) was used to thermal and mechanical properties. |
