| 摘要 |
The present invention relates to a process which comprises the non-hydrolytic transformation of an aluminoxane precursor composition, comprising carbon-to-oxygen bonds which can be alkylated by an alkylaluminum moiety, into a catalytically useful aluminoxane composition. In one embodiment of this invention, the catalytically useful aluminoxane composition is a polymethylaluminoxane composition substantially free of trimethylaluminum. The intermediate precursor is formed by the reaction of a trialkylaluminum compound, or a mixture of trialkylaluminum compounds, and a compound containing a carbon-to-oxygen bond, such as an alcohol, ketone, carboxylic acid, or carbon dioxide. Either unsupported or supported polymethylaluminoxane compositions can be formed. |
