From the author: The thermophysical properties of mixtures of thermoplastic resins and blowing agents, together with the knowledge of the solubilities of these components, are the basis for the manufacturing of plastic foams. In this work, the solubilities of blowing agents trichlorofluoro-methane, dichlorodifluoromethane, chlorodifluorome-hane, and 1,2-dichloro-1,1,2,2-tetrafluoroethane in thermoplastic resins poly(styrene), high density poly(ethylene), low density poly(ethylene), poly(propylene), poly(vinyl chloride), poly(carbonate) and poly(propylene oxide) were modeled by using the Perturbed Chain-Statistical Associating Fluid Theory (PC-SAFT) and the Sanchez-Lacombe equations of state (EoS), fitting a single temperature-dependent binary interaction parameter. PC-SAFT is a theoretically based equation of state with three pure component parameters that describe efficiently the thermodynamics of complex systems. Earlier works with this EoS have already predicted the phase coexistence properties of various refrigerants and higher order alkane series compounds, along with their mixtures. The pure component parameters for the blowing agents were obtained by regression of vapor pressure and liquid density data, while the pure component parameters for the thermoplastic resins were obtained by regression of pure liquid PVT data. The parameter estimation was performed by using a modified maximum likelihood method. The solubility results obtained with both EoS have been compared; the results from PC-SAFT showed a higher accuracy in terms of solubility pressure deviations. POLYM. ENG. SCI., 50:365-372, 2010.
