聚合物是复杂的混合物，即使它们只包含具有相同化学组成的成分，它们的组成也可能有很大的不同。定性地描述了链长分布对聚合物溶液在单一溶剂中相行为的影响。为了定量地理解这些现象，发展了一种基于Flory-Huggins关系的混合自由能的数值计算方法。给出了一些算例，并对结果的准确性和可靠性进行了讨论。
Polymers are complex mixtures that may have widely different compositions even if they contain only components having the same chemical constitution. The effect of the chain length distribution on the phase behavior of polymer solutions in a single solvent is described qualitatively. To obtain a quantitative understanding of these phenomena a numerical calculation method is developed which is based on the Flory-Huggins relation for the free energy of mixing. Some examples are presented, and the accuracy and the reliability of the results are discussed.
