  • Low-chlorine, polyolefin-substituted, with amine reacted, alpha-beta unsaturated carboxylic compounds
    Patent number: 7238650
    Abstract: A composition of matter comprising an amine acylated with a hydrocarbyl group substituted carboxylic acylating agent containing an average of from 1.3 to 1.6 groups derived from ?,?-unsaturated carboxylic compounds per Mn of the hydrocarbyl group, wherein the hydrocarbyl group has Mn determined by GPC ranging from 1500 to 3000, the amine comprises polyamine bottoms and said acylated amine has total base number (TBN) ranging from 17 to 35. A method for preparing the composition, lubricating oils containing the composition and, in another embodiment, lubricating oil compositions of this invention further comprising a metal overbased sulfonate detergent.
