    摘要: 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.
