Abstract: 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.

Abstract: A lubricant composition comprising an oil of lubricating viscosity, an amino-functionalized acrylic or methacrylic-containing polymer, comprising about 2 percent to about 8 by weight of an amine moiety bearing a tertiary amino group, attached to said polymer through an ester, amide, or imide linkage; and a nitrogen-containing dispersant, provides reduced friction to an internal combustion engine and improved fuel economy.
