中文摘要 | cloud point curves reported in the literature for five representatives of the system poly(vinyl methyl ether)/polystyrene were evaluated theoretically by means of the sanchez-lacombe lattice fluid theory. the measured phase separation behavior can be described within experimental error using only one adjustable parameter (quantifying the interaction between the unlike mers). the flory-huggins interaction parameters calculated from this theoretical description depend in good approximation linearly on composition (volume fractions) and on the inverse temperature. an evaluation of these data yields a maximum heat effect which is almost one order of magnitude less (ca. -0.25 j/cm(3)) than obtained via hess's cycle (dissolution of the components and of the blend) from calorimetric measurements. model calculations on the basis of the present theory demonstrate that the critical points shift to a different extent upon a certain relative change in the molar mass of the blend components. the sensitivity of the calculated phase diagrams against changes in the scaling parameter decreases in the following order: interaction energies between unlike mers, differences in the scaling temperatures, pressures and densities. |
