Azide polymers samples were analyzed by FT-MIR in order to develop a quantitative methodology to determine the C, H and N content in energetic polymers used in propellants. The elemental analysis data were used as reference. The FT-MIR results show a good agreement with CHN analysis. A good linear relationship was obtained suggesting that the methodology developed in the CTA laboratory can be used for quality control of these energetic polymers.
