摘要：
采用电导法对一系列疏水改性聚丙烯酰胺的溶解性进行了研究。考察了疏水基含量、分子量大小、阴离子基团种类及聚合物试样颗粒大小对溶解速度的影响。结果发现,在相同条件下,疏水改性聚丙烯酰胺的溶解时间远远长于聚丙烯酰胺的溶解时间。疏水基含量越高,溶解速度越慢;分子量越高,溶解速度越慢;聚合物颗粒越大,溶解速度越慢。实验结果证实了采用电导法研究疏水缔合聚合物溶解性的可行性。

Abstract:
The solubility of a series of hydrophobic modified poly-acryamides (HMPAM) has been measured by conductometric technique. The influences of some structural parameters such as content of hydrophobic group, type of the anionic group, molecular weight and particle size of HMPAM on its dissolution rate has been investigated. Results show that the dissolution time of HMPAM was much longer than that of polyacryamide; the higher the content of the hydrophobic group, the slower the dissolution time; the higher the molecular weight, or the lager the particle size, the longer the dissolution time will be need. These conclusions have proved the feasibility of the way to measure the solubility of the hydrophobically associating the water-soluble polymer by conductometry method.
Key words: water-soluble polymer, hydrophobic modified polyacryamide, solubility, conductometry
