| titleOfInvention | A kind of acrylamide copolymer and its preparation method and application |
| abstract | The present invention relates to petrochemical industry, a kind of acrylamide copolymer and its preparation method and application is disclosed.The acrylamide copolymer contains structural unit A, structural unit B and structural unit C, wherein, the structural unit A is the unit with structure shown in formula (1), the structural unit B is at least one of the unit with structure shown in formula (2)-formula (7), the structural unit C is the unit with structure shown in formula (8), and the weight ratio of three kinds of structural units is 1:0.001-10:0.001-10, the viscosity average molecular weigh of the acrylamide copolymer is 1,000,000-4,000 ten thousand.Copolymer good water solubility of the invention, residual monomer content are low, especially high temperature and it is with high salt under conditions of, apparent viscosity, thickening properties and the dispersed oil ability of solution are substantially improved compared with conventional polypropylene amide. |
