摘要：以共聚硬球链流体的分子热力学模型为基础，通过引入链节间方阱位能相互作用的贡献。建立了实际共聚高分子系统的分子热力学模型，对纯共聚高分子ＰＶＴ的关系结果，平均相对误差为０．２２％－０．８０％。
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 al[10].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%.
