Abstract
Novel polymerizable surface-active monomers were synthesized by successive treatment of polyoxyethylene 4-nonyl-2-prpylene-phenyl ether ammonium sulfate with maleic anhydride in the presence of hydroquinone at temperature of 180 degrees C. The molecular structures of the polymerizable surfactants were confirmed by H-1 and C-13 NMR spectroscopy. The surface tension isotherms on the air-water solution interface were obtained. The critical micelle concentrations (cmc) as well as the surface tension at the cmc were determined for these substances. The micellization and adsorption of the prepared anionic surfactants have been investigated by surface tension, and cloud point measurements. Surface parameters such as surface excess concentration ((max)), the area per molecule at interface (A(min)) and the effectiveness of surface tension reduction ((CMC)) were determined from the adsorption isotherms of the prepared surfactants.
