Synthesis of poly[methyl(3,3,3-trinuoropropyl)siloxane]b-poly(ethylene oxide)block copolymers

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).
