DOCUMENT TYPE: Journal CA Section: 50 (Propellants and Explosives) An investigation of LOVA (low-vulnerability ammunition) propellant aging was performed to identify the cause of stabilization periods in certain propellant lots. Two important observations were made: (1) the level of residual solvent in propellant grains slowly decreased in storage, and (2) during the drying process and while the grains were in storage, plasticizer "co-migrated" with solvent, resulting in plasticizer accumulation at grain surfaces. During storage, residual solvent may be oxidized to generate org. acids. Based on these results, it was proposed that stabilization periods resulted from processes related to migration, evapn., and oxidn.In this experiment, several chemicals are used like 25103-52-0 and 64-19-7 of residual solvent. .
