摘要: A new instrument for measuring accurate P–V–T relations of polymer solutions and liquid crystals observing their optical properties under pressure microscope has been constructed. The a poly(dimethylsiloxane)–benzene system were measured in the range 303.15–323.15 K at up to 140 bar. isothermal compressibilities (KT) thermal expansion coefficients (αP) determined from then composition dependence KT αP was discussed. We that KT-composition this linear each temperature within experimental plots against concentrations poly(dimethylsiloxane) benzene had curvature with positive deviation linearity. concentration internal pressure, (∂U/∂V)T, also
