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).

测定了二元混合物二甲醚（DME）+正戊烷（C ₅）的等容-等容实验相平衡数据 。三元混合物：DME + C ₅  +聚丁二烯（PB）；四元混合物DME + C ₅  + PB +氢（H ₂）。在变化的总密度（ρ）和变化的C ₅量下进行了二元实验。在每种光溶剂的ρ和相对量变化的情况下进行了三元实验。在四元混合物的情况下，聚合物的质量分数保持恒定，并且H ₂的量和ρ是变化的。使用扰动链统计缔合流体理论（PC-SAFT）状态方程（EoS）对二元和三元混合物获得的实验数据进行关联。
