Abstract

Dynamic and isothermal thermogravimetry were used to examine under atmospheric pressure the migration of a nitrate ester plasticizer from samples of K-1 model formulation simulating the solid rocket propellant of the NEPE type into the ambient environment (argon). The mass evaporation rate of the plasticizer from the sample surface and the loss of its mass in the stage of migration limited by the diffusion rate were estimated. The diffusion coefficients of the plasticizer were determined at temperatures of 55 to 100°C.
