实验测定了磺化聚砜钠盐在无外加盐存在下在二甲基甲酰胺溶液中的粘性行为,提出了一个新的经验公式: η_(sp)/C=D+A/(1+BC~n)用以描述聚电解质溶液的比浓粘度与浓度的依赖关系。利用经验式对我们及Fuoss等的实验数据进行处理时,所得结果是满意的。用“电粘滞效应”和聚离子链伸展效应对经验式进行了讨论。
The viscous behavior of sulfonated polysulfone sodium salt in dimethylformamide solution without any added salt was experimentally determined. A new empirical formula was proposed: η sp / C = D + A / 1 + BC ~ n) to describe the dependence of the reduced viscosity and concentration of the polyelectrolyte solution. The empirical results obtained from the empirical data of Fuoss and others are satisfactory. The empirical formula is discussed with the “electrical sticking effect” and the effect of polyion chains stretching.
