【Abstract】 The molecular thermodynamic model for chainlike fluids has been extended to the correlation of pVT relationships for the following systems : polystyrene with poly(2,6dimethyl phenylene oxide), polystyrene with poly(vinyl methyl ether), polystyrene with polybutadiene, polyethersulphone with poly(ethylene oxide), polyisobutylene with benzene, polyisobutylene with cyclohexane and polydimethylsiloxane with cyclohexane, respectively. It is shown that this model can be used to correlate the pVT relationships of binary polymer mixtures with only one adjustable temperature independent interaction parameter. Good agreement can also been obtained between predicted the specific volume and experimental data for the selected systems.更多还原
