Abstract: A series of hydrophobically associating polyampholytes[poly(AM/DMC/C11AM)] was synthesized by the free radical polymerization in water. In this process, C11AM was synthesized by Ritter reaction, and used to copolymerize with acrylamide(AM) and [2-(methacryloyloxy)ethyl] trimethylammonium chloride. The structure of C11AM and poly(AM/DMC/C11AM) were confirmed by 1H NMR. Moreover, the rheology measurement and fluorescent characterization show that poly(AM/DMC/C11AM) possessed both of the hydrophobic association and antipolyelectrolyte behavior, which resulted in the super salt-resistance of the obtained polymers.

Key words: Anionic hydrophobic monomer, Hydrophobically associating polyampholyte, Hydrophobic association, Anti-polyelectrolyte behavior, Salt-resistance
