摘　　要：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-functlonal 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）.一系列新 amphiphilic poly [甲基(3,3,3-trifluoropropyl ) siloxane ]-b-poly(ethylene 氧化物)(PMTFPS-b-PEO ) 把钓饵轻轻放进水里有到吸水的片断的恐水病的片断的不同比率的锁共聚物被联合结束功能的 PMTFPS 和 PEO 人聚合物的反应准备。共聚物被显示由象胶化浸透层析(GPC ) 和 <SUP>1</SUP 那样的描述是明确、狭窄的分子的重量分布(MWD )(1.07 &#8764;1.3 )> H-nudear 磁性的回声(<SUP>1</SUP > H-NMR ) 。
