蒂恩在形式上与哈金斯一模一样。这为后者在非常广泛的链长范围内提供了极好的支持，比重新烷烃系列中可能的链长大许多倍，Garner4和同事之前的工作表明了对该系列的同意(高达C70)，他们也试图从理论上证明他们的结果是合理的。在这两个系列中，对于少于20个原子的链，该关系都不成立。由此发现，Huggins热力学导出的凝固点方程与较高聚氧乙二醇组分的凝固点数据之间的一致性是这一系列合成聚合物纯度(链长的一致性)的重要补充证据。
tion is identical in form with that of Huggins. This provides excellent support for the latter over a very wide range of chain lengths, many times greater than is possible in the re-alkane series, agreement for which (up to C70) is shown by the previous work of Garner4 and co-workers, who also have attempted to justify their results theo-retically. 5 In both series the relation fails for chains of less than 20 atoms. The agreement thus found between Huggins’ thermodynamically derived freezing point equa-tion and the freezing point datafor the higher polyoxyethylene glycols is important additional evidence for the purity (uniformity of chain length) of this series of synthetic polymers.
