| titleOfInvention | Salt-tolerant quinary hydrophobic association polymer and preparation method and application thereof |
| abstract | The invention provides a salt-tolerant quinary hydrophobic association polymer and a preparation method thereof, wherein the quinary hydrophobic association polymer is prepared from acrylamide, acrylic acid, 2-acrylamido-2-methylpropanesulfonic acid, sodium p-styrenesulfonate and a hydrophobic monomer; the preparation process comprises the following steps: mixing acrylamide, acrylic acid, 2-acrylamide-2-methylpropanesulfonic acid, sodium p-styrenesulfonate and hydrophobic monomer to obtain a mixture, adding water into the mixture to prepare an aqueous solution with the mass concentration of the mixture being 25-30%, adding sodium dodecyl sulfate into the aqueous solution, uniformly mixing, then carrying out deoxidization treatment, adding an initiator with the mass of 0.05-0.3% of the mixture into the aqueous solution, continuing to react for 6-8 hours to obtain a pentapolymer, shearing the pentapolymer, soaking in absolute ethyl alcohol, drying and pulverizing to obtain the pentapolymer. The quinary hydrophobic association polymer can effectively solve the problems of poor salt tolerance and low temperature resistance of the existing quaternary hydrophobic polymer. |
