Abstract: The present invention relates to novel lubricant additives for improving the tribological properties, novel lubricants containing these additives, processes for the preparation thereof and the use thereof.

Abstract: A composition including a) rubber, b) crosslinking agent, c) metals and/or chalcogenides of metals as crosslinking aids and/or antiaging agents is described, wherein at least one of components b) or c) is in the form of composite particles composed of carrier particles to whose surface particles of the active material having an average diameter of less than 25 ?m are applied and layers thereof having an average layer thickness of less than 25 ?m and/or conglomerates of multiple carrier particles to whose surface particles of active material having an average diameter of less than 25 ?m are applied or layers thereof having an average layer thickness of less than 25 ?m and d) optionally other conventional additives. The composite particles make it possible to lower the active material content while achieving comparable properties or improving the aging resistance of elastomers and/or increasing productivity.

Abstract: A sheet consisting of a carrier medium, where at least one antimicrobial substance is incorporated into the carrier medium, is, in view of the task of specifying a sheet that exhibits high reactivity of the antimicrobial substance, characterized by the fact that the substance is in colloidal and/or nanoscale form. Moreover, the sheet is characterized by the fact that the substance is contained in a layer that is at least area wise interrupted or consists of unconnected partial layers. Moreover, a use of the sheet as a cleaning article or in a cleaning article is described.
