Description

Trimethylammonium group-attached polyacrylamide gel was synthesized from acrylamide (AAm) and N- (3- (trimethylammonio) propyl) acrylamide chloride salt (TMAPAAC), and its swelling behavior in aqueous surfactant solutions was investigated. In SDS (sodium dodecylsulfate) solution, the gel exhibited a drastic volume decrease at around 10-4mol dm-3 and gave a minimum volume at 8×10-4mol dm-3. In more concentrated solution, however, the gel exhibited an increase in volume. This behavior was caused probably by the different interactions of the surfactant molecules with the polymer-attached cationic groups and the hydorophobic polymer chain.
