Abstract
A new class of dispersant compounds and compositions and a series of novel lubricant compositions are disclosed. Polyalkylene glycol succinimides which may be derived from maleic acids and anhydrides are useful as dispersants in, for example, polyglycol base fluids. Lubricating compositions including such dispersant compositions are also described.
