PARTICLES SUPERFICIALLY MODIFIED BY HYDROPHILIC AND HYDROPHOBIC GROUPS |
| 摘要 |
Particles less than 100 mu m in size and modified by hydrophilic and hydrophobic groups wherein the hydrophilic and hydrophobic groups are distributed anisotropically on the surface of the modified particles. Processes for the preparation of such particles and the use of such particles as surface active products, especially for stabilizing or destablizing emulsions and foams as well as for tertiary oil recovery. |
