| titleOfInvention | Acrylamide copolymer and preparation method and application thereof |
| abstract | The invention relates to the field of petrochemical industry, and discloses an acrylamide copolymer and a preparation method and application thereof. The acrylamide copolymer comprises a structural unit A, a structural unit B and a structural unit C, wherein the structural unit A is a unit with a structure shown in a formula (1), the structural unit B is at least one of units with structures shown in formulas (2) to (7), the structural unit C is a unit with a structure shown in a formula (8), and the weight ratio of the three structural units is 1: 0.001-10: 0.001 to 10, and the viscosity average molecular weight of the acrylamide copolymer is 100 to 4000 ten thousand. The copolymer has good water solubility and low residual monomer content, and the apparent viscosity, thickening performance and oil dispersing capacity of the solution are greatly improved compared with the conventional polyacrylamide particularly under the conditions of high temperature and high salt. |
