    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.

    摘要: The invention relates to a nonflake coated coloring pigment which consists of an inorganic or organic, amorphous or partially crystalline material and which is provided with at least one coating, where each layer comprises at least one cured melamine-formaldehyde resin or consists of one such resin. The pigment is particularly readily suitable for producing cosmetic products. It confers a pleasant skin sensation to the user of the cosmetic products.
