The experimental results show that hydrophobic association increases obviously with increasing polymer concentration, hydrophobe content, hydrophobic side chain length and temperature. The Critical aggregate concentration of P (AM/NaAA/C8AM) with different hydrophobic content is 1.5~3g/L. Strong association between surfactant sodium dodecyl sulfate and P (AM/NaAA/C8AM) occurs through the formation of mixed micelles. The CMC of SDS is 8×10^(-3)mol/L. Moreover, because of the presence of-COOH group, the terpolymers have pH-responsive characterization. The hydrophobical association changes greatly with increasing pH.
