溶液中各组分的活度系数及其随温度的变化,是与溶液性质有关的基本物理化学数据,它反映出溶液中溶剂分子和溶质分子之间的相互作用,是研究溶液性质所不可少的。对于高聚物溶液性质的了解,溶液中各组分活度系数的测定也是必要的工作,但迄今在这方面的工作不多,我们认为有必要弥补这一缺陷。
Activity coefficients of components in solution and their changes with temperature are basic physico-chemical data related to the nature of the solution, which reflects the interaction between solvent molecules and solute molecules in solution and is essential for the study of solution properties of. For the understanding of the nature of the polymer solution, it is also necessary to measure the activity coefficient of each component in solution, but so far little work has been done in this area and we consider it necessary to remedy this deficiency.
