    Abstract: The present invention relates to additives for use in lubricant compositions to processes for producing the additives, and to the use of the additives in lubricants and in systems that are lubricated. More specifically, the additive includes a capped particle comprising: (i) one or more inorganic core particles; and (ii) one or more multi-block copolymers attached to the inorganic particles. The multi-block copolymer includes at least one nonpolar polymer block interposed between two polar polymer blocks. One polar polymer block is attached to the core particle, and at least a portion of the another polar polymer block is not directly attached to the core particle. When used in a lubricant to lubricate a metallic surface of a workpiece, the capped particle preferably adheres to the metallic surface of the workpiece.

    Abstract: The present invention concerns a high-temperature lubricant for the hot shaping of high-grade and carbon steels, which has a content of graphite, organic blowing agent and inorganic separation agent, and the use thereof. In order to provide a high-temperature lubricant which can be used for a wide range of steel qualities for different wall thicknesses to be rolled and stretching effects and which is moreover stable in respect of temperature, provides constant rolling results upon a change in the wall thickness and/or the quality of steel and does not lead to unwanted cementation of the rolled material, the high-temperature lubricant according to the invention contains at least the following constituents in percent by weight with respect to the solids content: (a) 40 to 90% by weight graphite, (b) 2 to 50% by weight organic blowing agent, and (c) 5 to 50% by weight inorganic separation agent, wherein the organic blowing agent (b) is selected from the group consisting of melamine, melam, melem, melon, phosphate salts and polyphosphate salts of the aforesaid compounds with phosphate chain lengths in the region of n=1 to 1000, reaction products and adducts of the aforesaid compounds with cyanuric acid or isocyanuric acid, and mixtures of the aforesaid, and the inorganic separation agent (c) is a sheet silicate or a mixture of sheet silicates.
