| 摘要 |
The present invention relates to a process for the preparation of oligomeric alkylaluminoxanes of the general formulae: <IMAGE> +TR <IMAGE> in which R=C1-C6-alkyl, preferably methyl, and n=2-40, preferably 10-20, by reacting aluminum salts containing water of crystallization, preferably aluminum sulfate containing water of crystallization, with an aluminum trialkyl, preferably aluminum trimethyl. Aluminoxanes of this type can be used as a catalyst component in the preparation of high-activity, homogeneous Ziegler catalysts. |
