| 中文摘要 | the cloud-point temperatures (t-c1's) of ti-ans-decahydronaphthalene (td)/polystyrene (ps, m-w = 270 kg/mol) solutions were determined by fight scattering measurements over a range of temperatures (1-16 degreesc), pressures (100-900 bar), and compositions (4.2-21.6 vol% polymer). the system phase separates upon cooling and the t-c1 was found to increase with the rising pressure for the constant composition. in the absence of special effects this finding indicates positive excess volumes. the special attention was paid to the demixing temperatures as a function of the pressure for the different polymer solutions and the plots in the t-volume fraction plane and p-volume fraction plane. the cloud-point curves of polymer solutions under changing pressures were observed for different compositions, demonstrates that the td/ps system exhibits ucst (phase separation upon cooling) behavior. with this data the phase diagrams under pressure were calculated applying the sanchez-lacombe (sl) lattice fluid theory. furthermore, the cause of phase separation, i.e., the influence of flory-huggins (fh) interaction parameter under pressure was investigated. |
