ABSTRACT:
The present invention is directed to oil-soluble lubricating oil additives comprising Mannich Base condensates of (A) a polymer substituted mono- or dicarboxylic acid material, (B) an optionally alkyl-substituted N-hydroxyaryl compound, (C) an aldehyde, and (D) an amido-amine or thioamido-amine wherein the polymer moiety of the mono- or dicarboxylic acid material is derived from a polymer of 300 to 10,000 number average molecular weight, and wherein the amido-amine and thioamido-amine reactants are derived by reacting polyamines and alpha, beta-unsaturated compounds. The Mannich Base condensates of this invention are useful as dispersants.
