ABSTRACT:
Poly(oxyalkylene) hydroxyaromatic esters having the formula: ##STR1## or a fuel-soluble salt thereof; where R.sub.1 and R.sub.2 are each independently hydrogen, hydroxy, lower alkyl having 1 to 6 carbon atoms, or lower alkoxy having 1 to 6 carbon atoms; R.sub.3 and R.sub.4 are each independently hydrogen or lower alkyl having 1 to 6 carbon atoms; R.sub.5 is hydrogen, alkyl having 1 to 30 carbon atoms, phenyl, aralkyl or alkaryl having 7 to 36 carbon atoms, or an acyl group having the formula: ##STR2## wherein R.sub.6 is alkyl having 1 to 30 carbon atoms, phenyl, or aralkyl or alkaryl having 7 to 36 carbon atoms; R.sub.7 and R.sub.8 are each independently hydrogen, hydroxy, lower alkyl having 1 to 6 carbon atoms, or lower alkoxy having 1 to 6 carbon atoms; n is an integer from 5 to 100; and x and y are each independently an integer from 0 to 10.
The poly(oxyalkylene) hydroxyaromatic esters of formula I are useful as fuel additives for the prevention and control of engine deposits.
