Hydrophobically associating water-soluble polymer is a novel functional polymeric material with a few hydrophobic groups in the hydrophilic macromolecular chain exhibiting excellent viscosifying action, thermal stability, salt tolerance and storage stability in aqueous solution because of its amphiphilic molecular structure. Latest advances in the research of molecular structure model and polymerization method are reviewed. The influences of following factors, such as molecular weight of polymer, ionic group in the polymer, hydrophobe content and type, sequence distribution of hydrophobic groups in the polymer chain, temperature, shear rate, salt and surfactant as well on behavior of polymer solution are reviewed. Applications in oil/gas exploitation, treatment of wastewater and sludge, coatings industry, biomedical field and reducing agent for turbulent drag are forecasted.
