Abstract: A polymer surfactant for improving engine oil emulsion properties of a lubricating composition mixed with water and/or fuel contamination, particularly at very cold temperatures, is described herein. In approaches, selected polymeric and functionalized compounds can impart both robust emulsion properties and simultaneously deliver good low temperature fluidity for lubricating compositions that may contain residual amounts of water and/or fuel contamination. Lubricating compositions including such surfactants demonstrate robust properties at temperatures down to about −30° C.

Abstract: A random copolymer suitable for reducing friction in lubricant compositions is disclosed. The random copolymer can include a short chain acrylate, a long chain acrylate, and a polar acrylate. The random copolymer can have a ratio of short chain acrylate to long chain acrylate of 0 to 2, and a molecular weight number of 1000 to 10000. The disclosure can include a lubricant containing a base oil and the random copolymer. A process for preparing the random copolymer and polymeric friction modifiers is also disclosed.
