Popis:	Phase behavior measurements of the (poly(lactic-co-glycolic acid) + dichloromethane + carbon dioxide) ternary system were taken using a variable-volume view cell at temperatures between 313.15 K and 363.15 K and at pressures up to 340 bar in poly(lactic-co-glycolic acid) weight fraction = 1.0 %, 2.0 %, and 3.0 %, respectively. To explain these systems, the hybrid equation of state (Peng–Robinson equation of state + SAFT equation of state) was applied with the van der Waals one-fluid mixing rule. The binary interaction parameters were obtained from the simplex method.
