Abstract: A hydrophobically modified polyacrylamide P(AM/2-EHA) was synthesized. By means of viscosity measurements, fluorescence, UV spectra, and SEM, the hydrophobic association properties of P (AM/2-EHA) in aqueous solution were studied. The results show that with the increase of P (AM/2-EHA) concentration, hydrophobic domain, super-molecular aggregate and even space network structure can be formed in the solution by the hydrophobic association of P (AM/2-EHA). And SEM analysis verified the formation of network microstructure.

Key words: hydrophobically modified polyacrylamide, solution properties, microstructure, hydrophobic association
