| 摘要 |
The present invention provides a polymeric species comprising a hydrophilic component that is responsive to, and which can bind with, a variety of metals, and a hydrophobic component. The hydrophobic component may be any organometallic polymer with surface-active properties, preferably a silicone polymer with hydrophobic organic radicals bound to the silicon. The hydrophilic component is comprised of multiple binding sites for metals, clustered in segments on the silcone such that more than one ligand (or binding site) can cooperatively bind a metal centre.
