Abstract Using acrylamide as the core monomer, polyacrylamide was initiated and catalyzed to prepare in the presence of coordination agents, dispersants, crosslinking agents or coupling agents. Polyacrylamide has active acyl groups and other molecular structures. The application performance of polyacrylamide could be improved through methods such as emulsification, flocculation, and composite crosslinking. Polyacrylamide was known as a "versatile additive" and a "universal product", widely used in thickening, stabilizing colloids, reducing drag, bonding, film-forming, biomedical materials, and other fields. Several preparation methods of ionic polyacrylamide in recent years were introduced, and elaborated on the latest progress in the development and application of polyacrylamide in petroleum mining, paper reinforcement, industrial water treatment, soil improvement, textile printing and dyeing, mineral utilization, and other fields.
