聚合物共混物的热力学相容性状态及其所得的相行为和机械性能在很大程度上取决于对混合自由能的热力学贡献和熵贡献之间的平衡。最近的应用程序，这热力学的考虑，审查了各种二元和三元共混物的均聚物和共聚物。本文讨论了用改进的Guggenheim准化学模型结合Sanchez格子流体模型从液体混合热数据预测聚合物共混物相容性和低临界溶解温度行为的最新进展。部分相容性思想的定性应用，在多相聚合物共混物的界面粘合。
The state of thermodynamic miscibility of a polymer blend and its resulting phase behavior and mechanical properties is largely determined by the balance between enthalpic and entropic contributions to the free energy of mixing. Recent applications of this thermodynamic consideration are reviewed for a variety of binary and ternary blends of homopolymers and copolymers. Recent advances in predicting polymer blend miscibility and Lower Critical Solution Temperature behavior from liquid heats of mixing data, through use of a modified Guggenheim quasichemical model combined with the Sanchez lattice fluid model are discussed. Qualitative application of partial miscibility ideas to interfacial adhesion in multiphase polymer blends is also presented.
