Abstract
A series of carboxylate-terminated monochelic polystyrenes were synthesized by anionic polymerization of styrene initiated with sec-butyllitluum, followed by reaction with CO 2 , acidification, and neutralization with different bases, i.e., alkali-metal hydroxyde and tetraalalkylammonium hydroxide. These functionalized polymers were studied by viscometry and light scattering. They were found to form aggregates or reverse micelles in solvents of low dielectric constant, i.e., cyclohexane, carbon tetrachloride, toluene, chloroform, etc. Well-defined aggregation numbers and critical micelle concentration (cmc's) were determined by curve fitting of light-scattering data
