| 제목 | Synthesis and thermal properties of glycidyl azide polymer based polyurethane |
| 초록 | Energetic thermoplastic elastomers contain polymer chain with highly energetic moiety such as azide (-N3) and nitrate(-NO3), which release high energy due to the exothermic scission. These elastomers have been studied and developed as a new generation binder for propellants and explosives. α, ω- hydroxyl telechelic glycidyl azide polymer (GAP) , which is one of the energetic binders, can react with isocyanates materials resulting in GAP-based polyurethanes. Thermosetting GAP-based polyurethanes had been researched. But the polyurethanes have some disadvantage that is not able to recycle. Otherwise thermoplastic GAP –based polyurethanes are recyclable. But GAP has secondary –OH groups that have less reactive than H2O. so the synthesis of GAP based thermoplastic polyurethane required fine controlled condition. In this study, thermoplastic GAP-based polyurethanes are synthesized and investigated the thermal properties of the GAP-based polyurethanes. |
