ABSTRACT:
A polyamine-containing poly(oxyalkylene) aromatic ester having the formula: ##STR1## or a fuel-soluble salt thereof; where R.sub.1 is a polyamine moiety having about 2 to about 12 amine nitrogen atoms and about 2 to about 40 carbon atoms, wherein the polyamine moiety is connected to the aromatic ring through one of its amine nitrogen atoms, R.sub.2 and R.sub.3 are independently hydrogen or lower alkyl and each R.sub.2 and R.sub.3 is independently selected in each --O--CHR.sub.2 --CHR.sub.3 -unit; R.sub.4 is hydrogen, alkyl having 1 to about 100 carbon atoms, phenyl, aralkyl having about 7 to about 100 carbon atoms or alkaryl having about 7 to about 100 carbon atoms, or an acyl group of the formula: ##STR2## where R.sub.5 is alkyl having 1 to about 30 carbon atoms, phenyl, aralkyl having about 7 to about 36 carbon atoms or alkaryl having about 7 to about 36 carbon atoms; and y is an integer from about 5 to about 100. The polyamine-containing poly(oxyalkylene) aromatic esters of the present invention are useful as fuel additives for the prevention and control of engine deposits.
