| 中文摘要 | the cloud-point temperatures (t-cl's) of poly(ethylene oxide) (peo) and poly(ethylene oxide)-block-polydimethylsiloxane (p(eo-b-dms)) homopolymer and block-oligomer mixtures were determined by turbidity measurements over a range of temperatures (105 to 130degrees), pressures (1 to 800 bar), and compositions (10-40 wt.-% peo). the system phase separates upon cooling and t-cl was found to decrease with an increase in pressure for a constant composition. in the absence of special effects, this finding indicates negative excess volumes. special attention was paid to the demixing temperatures as a function of the pressure for the different polymer mixtures and the plots in the t-phi plane (where phi signifies volume fractions). the cloud-point curves of the polymer mixture under pressures were observed for different compositions. the sanchez-lacombe (sl) lattice fluid theory was used to calculate the spinodals, the binodals, the flory-huggins (fh) interaction parameter, the enthalphy of mixing, and the volume changes of mixing. the calculated results show that modified p(eo-b-dms) scaling parameters with the new combining rules can describe the thermodynamics of the peo/p(eo-b-dms) system well with the sl theory. |
