A Study of n-Dodecylammonium Acrylamido-2-Methylpropanesulfonate Association in Aqueous Solutions

摘要

Association of a micelle-forming monomer, n-dodecylammonium 2-acrylamido-2-methylpro-panesulfonate, in aqueous solutions has been studied in a concentration range of 1.5 ×10~(-3)-2.5 × 10~(-1) M with the use of conductometry, capillary and rotational viscometry, isothermal translational diffusion, and atomic force microscopy. Two critical micelle concentrations have been determined, and the shape of n-dodecylammonium 2-acrylamido-2-methylpropanesulfonate micelles has been proposed.
