| titleOfInvention | 3-methacrylamide dopamine and acrylamide mixed polymer and preparation method and application thereof |
| abstract | The invention discloses a 3-methacrylamide dopamine and acrylamide mixed polymer, a preparation method and application thereof. The mixed polymer is prepared by the following steps: dissolving 3-methacrylamide dopamine and acrylamide in deionized water, and adjusting the pH value of the system to 7-11; adding an initiator and a catalyst into the aqueous solution obtained in the step (1) under an anaerobic condition, and reacting for 4-16 hours at the temperature of 30-60 ℃; adding ethanol or methanol, drying and dehydrating under heating, repeating for several times until the reaction product is dried, and grinding to obtain powdered product. The polymer of the invention has the performances of shear resistance, hydrolysis resistance at high temperature and hypersalinity resistance, and can greatly improve the oil displacement efficiency. |
