| 摘 要： | 本文以快速动态渗透压法,测定了磺化聚砜钠盐试样在无外加盐和有外加盐(NaNO_3)的二甲基甲酰胺中25±0.02℃时的渗透压,对实验现象进行了讨论,确认外加盐大于0.07N时,用渗透压法可以测得磺化聚砜的分子量。

| Abstract: | The osmotic pressure of Na-salts of sulfonated polysulfone with or without added salt were measured by rapid dynamic osmometry in DMF at 25±0.002℃. The phero-mona of experiment have been discussed. A method of determining molecular weight of sulfonated polysulfona with added salt above 0.07 N by Osmometry has been established. |
