摘要

介绍了目前国际学术界存在的对高分子溶液体系的溶剂优劣性的两种判断标准，即相互作用参数χ＝1／2和χ＝0，前者基于混合自由能，后者基于混合热。作者阐明了其倾向于采用后者的观点，而后者在目前国内所有高分子物理学教科书中均未被介绍。

Abstract

There are two kinds of judgement to goodness of the solvent in polymer solutions. One is χ=1/2

from the free energy of Flory-Huggins mean-field calculation and the second Virial coefficient in the expansion of the osmotic pressure for dilution solution; another is χ=0

from the mixing heat. The former occurs in the current textbooks about polymer physics in China

but the author prefers the latter and gives his reasons.
