摘要: 对ANPE-HAWP的增粘、耐温、抗盐和抗剪切性能进行了研究和评价,实验结果表明:ANPE-HAWP溶液具有临界缔合浓度(CAC );其耐温抗盐特性明显不同于P(AMPS-AM)参比样品;ANPE-HAWP的溶液结构具有快速可逆恢复的特点,剪切作用对ANPE-HAWP溶液结构所造成的破坏与自发进行的疏水缔合结构恢复的趋势可以达到动态平衡。拟合直线交点法对不同类型疏水缔合聚合物临界缔合浓度的测试结果说明ANPE-HAWP中的疏水基团能够更有效地参与分子间缔合结构的形成,从而在较低的浓度下形成了空间网络结构,从而初步验证了设计分子间高缔合比例HAWP是合理的和可行的。

Abstract:

The relationship among apparent viscosity, concentration and shear thinning behavior of ANPE-HAWP solution, as well as ability of resisting temperature and salt are studied. The experimental results indicate that ANPE-HAWP solution have obvious critical associating concentration(CAC ) and its ability of temperature tolerance and salt resistance is quite different from sample of reference P(AMPS-AM). Apparent viscosity at different shear rate shows that solution structure of ANPEHAWP can swiftly reversible restore. CAC of different type of HAWP are determined and experimental results verify the new HAWP molecular design idea of high-ratio inter-molecular association.

Key words: solution properties, temperature tolerance, salt resistance, shear thinning behavior, critical associating concentration (CAC), polymer
