Abstract: The rheology and association behavior of Hydrophobically modified poly (acrylic acid) (HMPA) solution under the condition of the existence of nonionic surfactant(TX-10) are investigated.The results show that the rheological behavior is related to the cluster overlapping concentration and the established network concentration C**.With the concentration increasing,the liquidlike behavior of HMPA solution transits to that of gellike.It is shown that HMPA interacts with the surfactant TX-10 in the solution.Surfactant induces the factors that change the number and strength of hydrophobic functions thus the associative network strength,and plays a major role in changing the solution rheology.

Key words: association, rheology behavoir, surfactant, solution properties, poly(acrylic acid)
