    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 (10) comprising: (i) one or more core particles (20) wherein the core particle is an inorganic particle having a dimension less than about 5 μm; and (ii) one or more multi-block copolymers (30) attached to the inorganic particles, wherein the multi-block copolymer comprises a) at least one nonpolar polymer block (51 ); b) at least one first polar polymer block (41 ); and c) at least one second polar polymer block (42); wherein the nonpolar polymer block is interposed between the first polar polymer block and the second polar polymer block, the first polar polymer block is attached to the core particle, and at least a portion of the second polar polymer block is not attached to the core particle. When used in a lubricant to lubricate a metallic surface of a workpiece (60), the capped particle preferably adhere to the metallic surface of the workpiece.

    Abstract: A composition comprising (a) fine spherical particles of an inorganic substance such as alumina, (b) an aqueous adhesive agent such as a petroleum resin emulsion, and water. It is preferred for better effect that the composition further comprises one or more selected from among (c) a wisker, (d) a powder of an inorganic substance in a form of a scaly crystal, (e) a powder of a metal hydroxide or an inorganic substance having bound water, and (f) a lubricant aid. The composition is free from problems of the occurrence of environmental pollution and the risk of misoperation of an automatic machine, which accompany a conventional graphite lubricating and releasing agent, and that of the danger of smoking or firing, which accompanies a conventional lubricating and releasing agent dispersed in an oil, and is useful as an aqueous lubricating and releasing agent for hot or cold forging using a non-graphite inorganic substance, which is free from occurrence of the deposition on a mold and an under fill phenomenon.
