Abstract: | Chelated aluminumalkoxides have been prepared from the reaction of aluminum-secbutoxide with acetylacetone (AcAc) or ethylacetoacetate (EAA) in different alkoxide/chelating agent molar ratios. These compounds have been used to study the possibility of controlling the rate of hydrolysis of aluminumalkoxides and/or the polycondensation of the related hydroxides. Hydrolysis was followed by NIR-spectroscopy and showed no differences for chelated aluminum-secbutoxide and the pure alkoxide. In contrast the polycondensation of aluminumhydroxides chelated with ethylacetoacetate decreased remarkably and depends on the alkoxide/chelating agent molar ratio. |
