A new energetic plasticizer, 2,2-Dinitro-1,3-propanediol (CAS NO.2736-80-3), has been characterized. Its high oxygen balance, +12.5%, and low glass transition temperature, -81.5 °C (midpoint), makes it very attractive as an energetic plasticizer in solid propellants. The ability of 2,2-Dinitro-1,3-propanediol (CAS NO.2736-80-3) to lower the glass transition temperature and viscosity of uncured PolyNIMMO has been studied and compared to other energetic plasticizers, such as BDNPA/F and butyl-NENA. It has a similar plasticizing effect as butyl-NENA, both on depressing the glass transition temperature and lowering the viscosity. To increase the poor thermal stability of NPN, several conventional nitrocellulose/nitroglycerine stabilizers were evaluated. Further work is however needed to find a more effective stabilizer. |
