摘要：
Compounds are described in which a phenolic moiety is linked by a Mannich base linkage to an alkylene-poly(oxyalkylene) moiety, and a polyamine moiety is linked to the alkylene-poly(oxyalkylene) moiety by a urea linkage involving one of the nitrogen atoms of the polyamine moiety. These compounds are highly effective detergent/dispersants for use in fuels and other media.
