To establish the relation between structure and properties of composite solid propellants it is important to know the structure of the elastomeric binder that has been used in the system. Therefore this study is focused on the characterization of polymers containing energetic groups that has been synthesized at ICT. ne characterization uses the wide spectral band of infrared, NIR/NIIR/FIR. This gives an identification of the analytical bands and allows quantitative and kinetic studies of these compounds.
