| 摘 要： | 通过自由基接枝共聚的方法，合成了改性的氧化淀粉-BA—MAA—Gd共聚物，采用红外光谱、扫描电镜、同步热分析、x射线粉末衍射等方法对产物进行了结构表征。用接枝物制备了电流变液，测定了在不同接枝物含量和电场强度下体系的电流变效应。实验结果表明：该电流变液体系的剪切应力随着电场强度的增大而增大；而在相同电场强度下，剪切应力则随电流变液中接枝物含量的增加而增大。 |

| Abstract: | To enhance the polarization of starch, the oxidized starch-BA-MAA-Gd copolymer was synthesized by radical graft copolymerization. The structure of the graft copolymer was determined by IR, scanning electron microscopy, state thermal analysis and X-ray diffraction. The electrorheological properties ot me graft copolymer were also investigated. The results show that shear stress increases with the increase of the graft copolymer loadings and the electric field in- tensity. |
| Keywords: | electrorheological fluid graft copolymefization starch rare earths |
