| description | The invention discloses modified polyacrylamide and a preparation method thereof, and polymer slurry. The preparation method comprises the following steps: dissolving an emulsifier, sodium alpha-olefin sulfonate and acrylamide in deionized water to prepare a first solution; dissolving allyl benzene hexacarboxylate in deionized water to prepare a second solution; dissolving an initiator in deionized water to prepare a third solution; dissolving a hydrophobic monomer and acrylic acid in deionized water to prepare a fourth solution; removing oxygen from the first solution, dropwise adding the second solution into the first solution, and carrying out heating to 60-65 DEG C; dropwise adding the third solution and the fourth solution at the same time and then conducting a reaction for 5-6 h; andadjusting the pH of a system to be 7-8, then continuing the stirring reaction and performing purification to obtain modified polyacrylamide, wherein the process of dropwise adding the second solution, the third solution and |
