The present invention relates to formulations comprising a) at least two different ZnO cubanes of which at least one ZnO cubane is present in solid form under SATP conditions and at least one ZnO cubane is present in liquid form under SATP conditions, and b) at least one solvent, to processes for producing semiconductive ZnO layers from these formulations, to the use of the formulations for producing electronic components and to the electronic components themselves.

Formulations comprising a mixture of ZnO cubanes and process using them to produce semiconductive ZnO layers

The invention relates to the use of nitrogenous aluminium organyl complexes of general formula (I) as co-catalysts in heterogeneous polymerisation reactions of propene. In said formula: R, R', Rand R&#x2032; independently of one another represent branched or unbranched C-Calkyl, cycloalkyl, alkenyl, cycloalkenyl, aryl or alkynyl; Rrepresents unsubstituted, monoalkylated or polyalkylated and/or monofluorinated or polyfluorinated aromatic hydrocarbons from group (II); Rand Rindependently of one another represent CH, CFoder C(R); m stands for 0, 1 or 2; n stands for 0, 1 or 2; o stands for 0 or 1, all independently of one another. Said systems exhibit improved characteristics in terms of activity and stereoselectivity in comparison to conventional co-catalysts such as AlEtand can act simultaneously as co-catalysts and stereoselectivity promoters 

Catalyst systems for Ziegler-Natta propene polymerisation

Disclosed are compounds of formula (I) which compounds are useful as cocatalysts in olefinic polymerisation reactions, e.g., as Ziegler-Natta catalysts.
