This invention relates to the field of water-soluble polymer materials technology, and discloses a comb-shaped ternary polymer and its preparation process. The polyacrylamide is polymerized from a backbone monomer, anionic monomer, comb-shaped macromolecular monomer, and optional functional reinforcing monomers under the action of a redox and azo-based composite initiation system. The preparation process includes solution preparation and neutralization, deoxygenation and temperature control, adiabatic polymerization, and post-treatment steps, employing a control strategy combining low-temperature initiation and adiabatic temperature rise polymerization. This invention effectively overcomes the defects of traditional linear polymers—low viscosity retention and poor shear resistance—in high-temperature and high-salt environments by introducing comb-shaped side chains to create a steric hindrance effect. The resulting product possesses ultra-high molecular weight, low water-insoluble content, and excellent solubility, exhibiting excellent salt-resistant thickening advantages and mechanical stability, meeting the oil displacement requirements of harsh reservoir environments.
