Abstract: Amphiphilic graft polymers were synthesized by hydrosilation using hydrophilic alkyl polyoxy-ethylene polyoxypropylene ether，hydrophobic organofluorine compoud or long-chain aliphatic acrylate and hydrophobic poly (methylhydrosiloxane). The structure of the samples were analyzed with FTIR and TEM. The results showed that the samples had favorable hydrophobic association. Moveover，the characteristics such as transmittance, rheological behavior，and surface tension are related to the contents of hydrophilic and hydrophobic groups and the chain length of the aliphatic acrylate.

摘要： 通过硅氢加成法制备了以丙烯酸长链烷基酯及聚硅氧烷为疏水性链段，以聚醚为亲水性链段的双亲水性接枝聚合物。采用红外光谱和透射电子显微镜对有关产物和其水分散物进行了结构分析，结果表明：聚合物水分散物具有良好的疏水缔合性；其透光率、流变性、表面张力等性能与亲水链段和疏水链段的含量及长链烷基酯链段长短等因素都有关系。
