A novel series of three anionic polymeric surfactants was prepared by polymerization of sulfonated styrene and allyl esters of long chain fatty acid chlorides (decanoyl, lauroyl and palmitoyl chloride). The unique structural features of these surfactants were confirmed by different spectroscopic tools (IR and H-NMR). The surface properties of these compounds such as surface tension, interfacial tension, emulsion stability, wetting power, foam height, solubilization and dispersant properties in disperse dye systems were determined and evaluated. A comparative study was done between the chemical structures and surface properties of these compounds. Biodegradability and stability to hydrolysis in acidic and alkaline medium were also determined and evaluated. |
