Abstract: The present invention relates to substituted perylene derivatives in which the substituent has a sterically stabilizing and/or electrostatically stabilizing effect. The perylene derivatives of the invention are particularly suitable as pigment dispersants. The present invention additionally relates to pigment preparations in which the perylene derivatives of the invention are used.

Abstract: The invention relates to the use of polyurethanes having hyperbranched structures, selected from hyperbranched polyurethanes with at least one group that has an affinity to pigments and modified hyperbranched polyurethanes, as polymer dispersants for pigments. The invention is preferably further characterized in that a hyperbranched polyurethane having 2 to 100 NCO groups and a molecular weight of 500 to 50.000 g is reacted with one or more polyether derivatives.

Abstract: A method of automated preparation and characterization of liquid multicomponent systems comprising at least two, preferably three components comprises the automated preparation of a mixture by combining at least two, preferably three components in a vessel, at least one component being metered in an automated fashion into the vessel, and the automated homogenization of the mixture with subsequent automated measuring and evaluation. The apparatus for conducting this method comprises at least one metering station, one closing station, one homogenizing station, one measuring station for determining formulation properties, and one evaluation unit.

Abstract: The present invention relates to a stereorigid transition metal compound having as ligands a cyclopentadienyl group and a substituted or unsubstituted heteroatom which are connected to one another via a monocyclic or polycyclic ring system, with the cyclopentadienyl group being fused onto the monocyclic or polycyclic ring system. The transition metal compound of the invention is suitable as a catalyst component for olefin polymerization.
