碩士 === 國立臺灣科技大學 === 纖維及高分子工程研究所 === 88 === Abstract A series of anionic surfactants have been synthesized by the reaction of polyoxyethylenated stearyl ether、polypropylene glycol、 epichlorohydrin, and fumaric acid. 1H-NMR、FTIR and element analysis have been used to confirm the structure of these compounds. These surfactants have been found to exhibit excellent surface active properties including reducing surface tension、pH buffer capacity、wetting power、metallic ions dispersancy and chelating capacity. These surfactants also have been found to exhibit the retardering abilities in direct dye-cotton dyeing system.
