| titleOfInvention | Difunctional associative drag reducer and synthetic method thereof |
| abstract | The invention discloses a bifunctional associative drag reducer and particularly discloses a preparation method of the drag reducer, wherein the method comprises the following steps: 1) synthesis of Polymer colloid: weighing a hydrophobic monomer and a surfactant, mixing, taking distilled water as a solvent, stirring the solution to be transparent, then adding a hydrophilic monomer, a metal ion chelating agent and a cosolvent, stirring to be completely dissolved, adjusting the pH value of the solution to 6-7, introducing nitrogen, continuously stirring, adding an initiating system, continuously introducing nitrogen, and reacting at constant temperature for 6-8 hours to obtain a polymer colloid; 2) synthesis of a drag reducer: shearing the polymer colloid obtained in the step 1), extracting, drying and the like to obtain the drag reducer. The drag reducer has both a tackifying effect and drag reduction performance. |
