ABSTRACT:
The present invention is directed to lubricating oil and fuel dispersants comprising hydroxy aromatic succinimide Mannich Base condensates of heavy polyamine. A heavy polyamine is a mixture of polyalkylenepolyamines comprising small amounts of lower polyamine oligomers such as tetraethylene pentamine and pentahexamine but primarily oligomers with 7 or more nitrogens, 2 or more primary amines per molecule, and more extensive branching than conventional polyamine mixtures.
