A novel series of six nonionic polymeric surfactants were prepared by polymerization of acrylated poly(ethylene glycol) (PEG, molecular weight MW = 400, 600 and 2,000) and allyl ester of long chain fatty acid chloride (decanoyl and lauroyl chloride). The unique structural features of these surfactants were confirmed by different spectroscopic tools (IR and 1 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 comparison study was done between the chemical structures and surface properties of such compounds. Biodegradability and stability to hydrolysis in acidic and alkaline media were also determined and evaluated.
