Sulfonate lycine type hydrophobic associated polymer and preparation method thereof |
| abstract |
The present invention discloses a sulfonate lycine type hydrophobic associated polymer and a preparation method thereof. A preparation process of the sulfonate lycine type hydrophobic associated polymer comprises the following steps: firstly, mixing acrylamide and acrylic acid in an aqueous solution; adjusting pH of the system to be around 6 to 8; adding 3-(dimethylamino propyl methacrylamide) propanesulfonate, N-aryl-N-alkyl (methyl) acrylamide and lauryl sodium sulfate and stirring till the solution is clear; and after nitrogen is introduced for deoxidization, adding a photoinitiator azobis (isobutylamidine hydrochloride) for performing polymerization under photoinitiation conditions. The sulfonate lycine type hydrophobic associated polymer integrates the advantages of a two-tailed hydrophobic associated polymer and the advantages of a lycine type polymer, such that the viscosifying property, the temperature resistance, the salt resistance and the hydrolysis resistance of the sulfonate lycine type hydrophobic associated polymer are remarkably improved. |
