Problems solved by technology

The hydrophobic part of the hydrophobic association polymer molecule is composed of non-polar groups, and there is only van der Waals attraction between them and water molecules, which is much weaker than the interaction hydrogen bond between water molecules, so it cannot effectively replace the interaction with water molecules. Water molecules interact with each other through hydrogen bonds

Description

technical field [0001] The invention relates to a method for testing the effect of the mass concentration of hydrophobically associated polymers on apparent viscosity. Background technique [0002] Hydrophobic association polymer refers to a water-soluble polymer with a small amount of hydrophobic groups on the hydrophilic macromolecular chain of the polymer. A small amount of hydrophobic groups are introduced into the water-soluble macromolecular chain to make its aqueous solution exhibit unique rheological properties. Above a certain polymer concentration, the hydrophobic parts associate to form a dynamic three-dimensional network structure, thereby forming a large supramolecular chain aggregate, increasing the hydrodynamic volume of the polymer, and significantly increasing the viscosity of the solution. The addition of small molecule electrolytes can increase the polarity of the solvent, enhance the hydrophobic association, and produce obvious salt resistance. Under th...
