    摘要: The present invention relates to novel oxygen-containing organoaluminium complexes of the general formula (I) in which R1, independently of one another, denote branched or unbranched C1-C7-alkyl, -cycloalkyl, -alkenyl, -cycloalkenyl, -aryl or -alkynyl; R2 denotes unsubstituted, mono- or polyalkylated and/or mono- or polyfluorinated aromatic hydrocarbons from the group R3, R4, independently of one another, denote CH2, CF2 or C(R1)2; independently of one another, m denotes 0, 1, 2 n denotes 0, 1, 2. These compounds can serve as cocatalysts in olefinic polymerisation reactions. In particular, they can be employed for the preparation of novel Ziegler-Natta catalysts having improved properties, in particular having higher activities compared with conventional Ziegler-Natta catalysts with AlEt3, as cocatalyst, or of novel coordination catalyst systems which have higher activities than conventional Ziegler-Natta catalysts, even at low temperatures, such as 60° C., and a pressure of 2 bar.
