    摘要: Reaction products which provide antioxidant properties to lubricants and fuels while serving as effective dispersants and detergents in these mediums. These products, of the reaction of a hydroxyalkylene substituted polyamines and substituted succinic anhydrides, contain mixtures of esters, amides and imides. Furthermore, preferred embodiments of the reaction products have pendent alcohol groups which provide extra dispersancy and detergency over traditional dispersants which typically do not have alcohol groups.
