| Abstract: | A molecular thermodynamic model for copolymer systems was developed based on the equation of state for heteronuclear hard-sphere chain fluids presented by Hu et al10].The model consists of two contributions:the equation of state for hard-sphere chain fluids as a reference,a square-well potential term as a perturbation.pVT data of molten pure copolymer was correlated by this model.It was shown that good agreement between experimental data and calculated results could be obtained with only one adjustable interaction parameter. The mean relative deviation was 0.22%~0.80%. |
