Abstract
Abstract Disclosed are polyamino alkenyl or alkyl succinimides which have been modified by treatment with a lactone to yield polyamino alkenyl or alkyl succinimides wherein one or more of the basic nitrogens of the polyamino moiety is substituted with a hydrocarbylcarbonylalkylene group. The additives so disclosed are useful as dispersants in lubricating oils, gasolines, marine crankcase oils and hydraulic oils.
