ABSTRACT:
The present invention is directed to oil-soluble lubricating oil additives comprising Mannich Base condensates of a polymer substituted hydroxy aromatic compound with formaldehyde and an amido-amine or thioamido-amine, wherein the polymer substituent is derived from a polymer of 300 to 10,000 number average molecular weight, and wherein the amido-amine and thioamido-amine comprises the reaction product of a polyamine and an alpha, beta-ethylenically unsaturated compound. The Mannich Base condensates of this invention are useful as dispersants in oleaginous compositions, including fuel and lubricating oil compositions, and in concentrates containing these additives.
