| 中文摘要 | the calculations presented in this paper are based on the sanchez-lacombe (sl) lattice fluid theory. the interaction energy parameter, g*(12)/k, required in this approach was obtained by fitting the cloud points of polystyrene (ps) /methyleyclohexane (mch) polymer solutions under pressure. the sl lattice fluid theory was used to calculate the spinodals, the binodals, and the flory-huggins (fh) interaction parameter of the solutions. the calculated results show that the sl lattice fluid theory can describe the dependences of thermodynamics of ps/mch solutions on temperature and pressure very well. however, the calculated enthalpy and the excess volume changes indicate that the clausius-clapeyron equation cannot be suitable to describe pressure effect on ps/mch solutions. further analysis on the thermodynamics of this system under pressure shows that the role of entropy is more important than the excess volume in the present case. |
