| 摘 要： | 综述了PC-SAFT状态方程在计算共聚物性质以及共聚物-溶剂相平衡方面的研究进展,介绍了用PC-SAFT状态方程计算的几种共聚物体系的相平衡以及计算值与实验值的比较情况。结果表明PC-SAFT状态方程可以很好地描述二元共聚物-溶剂体系的相平衡。此外,对于由极性和非极性重复单元构成的共聚物,需要用相互作用参数来校正不同类型重复单元之间的相互作用力。

| Abstract: | The recent progress in the calculation of copolymer physical properties and the phase equilibrium of copolymer-solvent system are introduced.The phase equilibrium of several copolymer systems is calculated by PC-SAFT state equation,and its result is compared with corresponding experimental data.Results show that the PC-SAFT state equation can describe the phase behavior of copolymer-solvent system well.Besides,copolymers comprising both non-polar and polar repeat units require an interaction parameter to in... |
