Abstract
Investigation of plasticizer levels in solid propellants has been carried out using three FTIR techniques: FTIR-microscopy (FTIR-mic), photoacoustic-FTIR (PA-FTIR), and gas chromatography-FTIR (GC-FTIR). Two plasticizers have been examined; only one of these appears to have a tendency to evaporate from the solid propellants. It was observed that when both plasticizers are present in the same formulation, evaporation of the more volatile plasticizer is notably decreased. Significantly higher levels of plasticizer and polymeric binder have been found at extruded surfaces than have been found in the interior of the grain. Desorption-GC-FTIR analysis revealed a relationship between processing conditions and residual solvent content.
