| 摘 要： | 研究了不同分子结构的疏水缔合聚合物和部分水解聚丙烯酰胺在45、55和65 ℃下的静态吸附特征。 实验结果表明，疏水缔合聚合物的疏水基含量和微嵌段长度可以改变聚合物在石英砂表面的最大吸附量，而其中疏水基含量是主要影响因素，等温吸附曲线出现2个平台区。 随着温度的升高， 部分水解聚丙烯酰胺吸附量增大，而缔合聚合物则表现出相反的规律；缔合聚合物通过改变疏水基含量和微嵌段长度来影响其吸附性能。

| Abstract: | The static adsorption properties of several water soluble polymers, including different kinds of partially hydrolyzed polyacryamide(HPAM) and hydrophobically associative water soluble polymers(HAWSPs), have been studied at 45 ℃, 55 ℃ and 65 ℃. The results show that the maximum adsorption of HAWSPs on sand is affected by the hydrophobe contents and the lengths of micro-block, with the former one playing the major role. The isothermal adsorption curves show two platform areas. The maximum adsorption of HPAM rises with the increase of temperature, but the situation for HAWSPs is in the contrary. It indicates that the hydrophobe contents and the lengths of micro-block may affect the adsorption. |
