| 摘要 |
A process is described for fixing an inorganic species in an organic matrix, which comprises bringing a compound of the formula MRn in which M is selected from sub-group metals, lanthanides, actinides, Al, Sn, B and Si, and the radicals R can be replaced by a complexing agent, into contact with a complexing agent, the complexing agent containing a functional group which is capable of participating in a polymerization or polycondensation reaction. After complexing, hydrolysis and condensation are preferably first carried out, followed by polymerization or polycondensation.
