Description
technical field [0001] The invention relates to a method for testing the influence of surfactant dosage on the intensity ratio of spectral vibration peaks. 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 the action of ...
