- Abstract
The 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.
