Exudation of plasticizers through a polymeric matrix still remains a persistent problem in the life cycle of polymer-bonded explosives. This article is concerned with the migration of two energetic plasticizers, K10 and GLYN oligomer, which are commonly employed in combination with energetic polymers such as polyGLYN. Isothermal thermogravimetric analysis was used to determine migration rates, where it was found that the oligomer migrates slower than the K10 plasticized binder systems with a polyGLYN binder. Migration rates follow an inverse correlation with molecular weight, as is the case for the oligomer over the K10 plasticizer.
