Summary: | 碩士 === 國立臺灣科技大學 === 高分子系 === 94 === In this study, Polyoxyethylenated stearyl ether was used as a main material to change the length of oxyethylenes ( n=7,15,20,30 ) and synthesized a series of ortho ester surfactants with TPG and TEOF. The structure of end product was confirmed by FT-IR, 1H-NMR and elemental analysis. The properties of cleavable ortho ester surfactants degraded in pH 4 , 7, 10 Buffer solution were studied. These properties contain surface tension, contact angle, foaming and emulsifying power .
