Loci of isochoric - isoplethic experimental phase equilibrium data, were determined for the binary mixture dimethyl ether (DME) + n-pentane (C5); the ternary mixture: DME + C5 + polybutadiene (PB); and the quaternary mixture DME + C5 + PB + hydrogen (H2). Binary experiments were performed at varying overall density (ρ) and varying quantity of C5. Ternary experiments were performed at varying ρ and varying relative quantities of each light solvent. In the case of quaternary mixtures, the mass fraction of polymer was kept constant, and the amount of H2 and ρ were varied. The experimental data obtained for binary and ternary mixtures were correlated using the Perturbed-Chain Statistical Associating Fluid Theory (PC-SAFT) equation of state (EoS).
