Features of the Interaction between Dodecyltrimethylammonium Bromide Micelles and Sodium 4-Styrene Sulfonate

Abstract

Spin probe EPR spectroscopy and UV spectroscopy have been employed to study the interaction between a hydrophobic anionic monomer, sodium styrene sulfonate, and micelles of a cationic surfactant, dodecyltrimethylammonium bromide. It has been shown that the interaction with the monomer decreases the critical micelle concentration of the surfactant in aqueous solutions. It has been found that the monomer is incorporated into micelles; therefore, the presence of the surfactant may hinder polymerization of the monomer.
