    Abstract: An oxidized, degraded interpolymer of ethylene and propylene is reacted with an unsaturated acid or derivative thereof, preferably maleic acid or anhydride, to form an acidic intermediate. This acidic intermediate is reacted with a polyamine to form a product which is useful as an additive in fuels, lubricant compositions and hydrocarbon oils.
