The stability in a high temperature of hydrophobically associating polyacrylamide in simulated Shengli brine was investigated by measuring its viscosity.
用粘度法研究了用模拟胜利油田盐水配制的疏水缔合聚丙烯酰胺溶液在高温下的稳定性。

Hydrophobically associating polymer (HAP) is a new and ideal polymer at present, which has the characteristics of salt -resistance, thermal endurance and shear-resistance.
疏水缔合聚合物是目前理想的抗盐抗温和抗剪切的新型聚合物。

The addition of small-molecule electrolyte increases the polarity of the solution can enhances the hydrophobically association action, thus making it obviously salt-resistance.
