碩士 === 國立臺灣科技大學 === 高分子系 === 94 === A series of novel surfactants containing multi-anionic and nonionic hydrophilic moiety are prepared by reacting fumaric acid with polyoxyethylenated stearyl ether in the presence of a peroxy-type free radical initiator to form a carboxylic acid group-containing addition product. The structure of these surfactants have confirmed by infrared, nuclear magnetic resonance and elemental analysis. These surfactants exhibit excellent functional properties of self-sequestering which mean besides good surfactant properties, including surface tension and fluorescence properties. In application on PET fibers bleaching procedures these surfactants increase the penetration of the fibers of grey fabrics and increase the whiteness of bleached PET fibers.
