摘要
We report the synthesis and structure determination of PS-block-PEO functionalized by fluorocarbon end-group (C8F17) via an ester bridge. The synthesis as done by an anionic polymerization of PS and POE terminated by grafting 3-perfluorooctylpropanoyle chloride (C8F17-CH4-COCl) onto PS-POE alcoholate. The structure has been characterized by a number of techniques: size exclusion chromatography. elementary analysis, UV spectroscopy, H-1 nuclear magnetic resonance. Those analyses have allowed the determination of the real molar mass of the copolymers and the percentage functionalization. Because of their well-defined structure. these copolymers can be used as model compounds for the determination of structure-property relationships. (C) 2002 Elsevier Science Ltd. All rights reserved.
