Title:
OXYGEN-CONTAINING ORGANOALUMINUM COMPLEXES USED AS COCATALYSTS
Kind Code:
A1
Abstract:
Abstract not available for EP1537128
Abstract of corresponding document: WO2004033466
The invention relates to novel oxygen-containing organoaluminum complexes of general formula (I) in which R<1> independently represents branched or unbranched C1-C7 alkyl, C1-C7 cycloalkyl, C1-C7 alkenyl, C1-C7 cycloalkenyl, C1-C7 aryl, or C1-C7 alkinyl; R<2> represents unsubstituted, monoalkylated or multialkylated, and/or monofluorinated or multifluorinated aromatic hydrocarbons from group; R<3> and R<4> independently represent CH2, CF2, or C(R<1>)2; and m and n each independently represent 0, 1, 2. Said compounds can be used as cocatalysts in olefinic polymer reactions, particularly for producing novel Ziegler-Natta catalysts having improved properties, especially higher activities than conventional Ziegler-Natta catalysts using AIEt3, as a cocatalyst, or novel coordination catalyst systems which have higher activities than conventional Ziegler-Natta catalysts already at temperatures as low as 60 DEG C and at a pressure of 2 bar.
