Abstract:

Hydrophobically associating polymers are distinctive water-soluble polymers with a few hydrophobic groups in the hydrophilic macromolecular chain. Because of its unique amphiphilic molecule structure, it has special rheological properties. Six hydrophobically associating polyacrylamide derivatives with different modification monomers were synthesized. Their intramolecular and intermolecular association behavior by internal factors such as the degree of polymerization, the block copolymer content as well as the size of hydrophobic groups and the external factors of the resistance to shear, salt tolerance were investigated. The hydrophobic chain can improved the viscosity and salt resistance of polymers.

Key words: Hydrophobic association, Polyacrylamide, Associating mechanism, Thickening property
