| 中文摘要 | the cloud-point temperatures (t-cl's) of trans-decahydronaphthalene(td)/polystyrene (ps, (m) over bar (w) = 270 000) solutions were determined by light scattering measurements over a range of temperatures (1-16degreesc), pressures (100-900 bar), and compositions (4.2-21.6 vol.-% polymer). the system phase separates upon cooling and t-cl was found to increase with rising pressure for constant composition. in the absence of special effects, this finding indicates positive excess volume for the mixing. special attention was paid to the demixing temperatures as a function of pressure for different polymer solutions and the plots in the t-phi plane (where phi signifies volume fractions). the cloud-point curves of polymer solutions under different pressures were observed for different compositions, which demonstrated that pressure has a greater effect on the td/ps solutions when far from the critical point as opposed to near the critical point. the sanchez-lacombe lattice fluid theory (sllft) was used to calculate the spinodals, the binodals, the flory-huggins (fh) interaction parameter, the enthalpy of mixing, and the volume changes of mixing. the calculated results show that modified ps scaling parameters can describe the thermodynamics of the td/ps system well. moreover the sllft describes the experimental results well. |
