Abstract
AbstractThe phase‐behavior data are presented for three kinds of commercial polymer‐bonded explosive (PBX) elastomers in dimethyl ether (DME). Ethylene‐co‐vinyl acetate (with vinyl acetate contents of 40 % (EVA40) and 60 % by mass (EVA60)) and alkyl acrylate (ACM) copolymers were used as the PBX elastomers. For each elastomer/DME system, the cloud‐ and/or bubble‐point (phase‐boundary) pressures were measured as a function of temperature and elastomer composition using a high‐pressure phase‐equilibrium apparatus equipped with a variable‐volume view cell. For the EVA60/DME system, the cloud‐point pressure increased as the EVA60 composition increased. The ACM elastomer was readily soluble in saturated liquid‐state DME at most temperature and elastomer composition ranges.
