    摘要: Additives useful as dispersants and/or detergents in lubricating oils, gasolines, marine crankcase oils and hydraulic oils are polyamino alkenyl or alkyl succinimides which have been modified to contain carbamate functionalities by converting one or more of the amino nitrogens to a hydrocarbyl carbamate, hydroxyhydrocarbyl carbamate or hydroxy poly(oxyalkylene) carbamate group. These additives can be prepared by reacting a polyamino alkenyl or alkyl succinimide with a cyclic carbonate, or a linear mono-or poly-carbonate, or a chloroformate.
