Abstract: A series of new amphiphilic poly[methyl(3,3,3-trifluoropropyl)siloxane]-b-poly(ethylene oxide) (PMTFPS-b-PEO) diblock copolymers with different ratios of hydrophobic segment to hydrophilic segment were prepared by coupling reactions of end-functional PMTFPS and PEO homopolymers. Copolymers were shown to be well defined and narrow molecular weight distribution (MWD) (1.07~1.3) by characterizations such as gel permeation chromatography (GPC) and ¹H-nudear magnetic resonance (¹H-NMR).
