To enhance the temperature, salt and shear resistance of conventional polyacrylamide oil-displacing agents, a fluorinated hydrophobically associating polymer AM-AA-HDFDMA was synthesized by aqueous solution polymerization. Acrylic acid (AA) and acrylamide (AM) were utilized as comonomers, with perfluorooctylethyl methacrylate (HDFDMA) serving as the fluorinated hydrophobic functional monomer. The synthesis employed an ammonium persulfate-sodium bisulfite (APS-NaHSO3) redox initiation system. The
