We have measured the P-V-T at molten state and swelling ratio at solid state under pressurized CO2 for poly(propylene) and re-determined the parameters of Sanchez-Lacombe (S-L) EOS by using the measured data. The prediction methodology for predicting various thermodynamic properties by using the S-L EOS with appropriate theory was presented. A comparison of prediction accuracy between the parameter sets indicated that the parameter set representing the P-V-T behavior well can predict the other properties such as viscosity, solubility and surface tension.
