Patent number: 10190071Abstract: The present invention relates to functional fluid compositions containing friction modifiers, and specifically stable compositions containing friction modifiers with limited solubility in and/or limited compatibility with the functional fluids with which they are used. In particular the present invention deals with functional fluids used in internal combustion engines, such as engine oils, and friction modifiers derived from hydroxy-carboxylic acids, where the friction modifier is present in the functional fluid composition at levels that would otherwise cause the composition to be unstable and/or hazy.Type: GrantFiled: October 19, 2015Date of Patent: January 29, 2019Assignee: The Lubrizol CorporationInventors: Ewan E. Delbridge, John J. Mullay, James D. Burrington, Jonathan R. Sharpe, John W. Dunkerley

Publication number: 20180030366Abstract: The invention provides a lubricating composition containing an oil of lubricating viscosity and a block copolymer. The block copolymer may contain (a) a hydrophobic first block having C1-30 alkyl (meth)acrylic units, wherein at least 50 wt % of the C1-30 alkyl (meth)acrylic units are C12-15 alkyl (meth)acrylic units, and up to 50 wt % of the C1-30 alkyl (meth)acrylic units are C16-20 alkyl (meth)acrylic units, with the proviso that alkyl groups of the C1-30 alkyl (meth)acrylic units have an average total number of carbon atoms of at least 8; and (b) a second block having (meth)acrylic units further having a heteroatom-containing group providing a polar group. The invention further relates to a method of lubricating an internal combustion engine by lubricating the engine with the lubricating composition. The invention further relates to the use of the block copolymer as an emulsifier and/or pour point depressant.Type: ApplicationFiled: October 12, 2017Publication date: February 1, 2018Inventors: Haihu Qin, Ying Wang, Marina Baum, Jack C. Kelley, Patrick E. Mosier, Michael J. Covitch, John J. Mullay
