Abstract
Compounds are described in which a phenolic moiety is linked to a polyamine moiety by means of a Mannich base linkage, and the polyamine moiety is linked to an alkylene-poly(oxyalkylene) moiety by means of a urea linkage in which one of the nitrogen atoms of the urea linkage is a nitrogen atom of the polyamine. These compounds useful as detergent/dispersants in fuels and other media.
