| 中文摘要 | polymer blends of poly(methyl methacrylate) (pmma) and poly(styrene-co-acrylonitrile) (san) with an acrylonitrile content of about 30 wt % were prepared by means of solution-casting and characterized by virtue of pressure-volume-temperature (pvt) dilatometry. the sanchez-lacombe (sl) lattice fluid theory was used to calculate the spinodals, the binodals, the flory-huggins (fh) interaction parameter, the enthalpy of the mixing, the volume change of the mixing, and the combinatorial and vacancy entropies of the mixing for the pmma/san system. a new volume-combining rule was used to evaluate the close-packed volume per mer, upsilon*, of the pmma/san blends. the calculated results showed that the new and the original volume-combining rules had a slight influence on the fh interaction parameter, the enthalpy of the mixing, and the combinatorial entropy of the mixing. moreover, the spinodals and the binodals calculated with the sl theory by means of the new volume-combining rule could coincide with the measured data for the pmma/san system with a lower critical solution temperature, whereas those obtained by means of the original one could not. |
