ABSTRACT:
The present invention is directed to oil-soluble lubricating oil additives comprising Mannich Base condensates of (A) an ethylene-alpha-olefin polymer substituted mono- or dicarboxylic acid material, (B) an optionally alkyl-substituted N-hydroxyaryl compound, (C) an aldehyde, and (D) an amine, wherein the polyer moiety of the mono- or dicarboxylic acid material is derived from at least one terminally unsaturated ethylene alpha-olefin copolymer of 300 to 10,000 number average molecular weight, wherein the terminal unsaturation comprises ethenylidene unsaturation. The Mannich Base condensates of this invention are useful as dispersants.
