Abstract
A fuel composition comprising a major amount of a normally liquid fuel and a minor amount of at least one compound of the general formula ##STR1## wherein each Ar is independently an aromatic group having from 4 to about 30 carbon atoms and from 0 to 3 optional substituents selected from the group consisting of amino, hydroxy- or alkyl- polyoxyalkyl, nitro, aminoalkyl, carboxy or combinations of two or more of said optional substituents, each R is independently a hydrocarbyl group, R.sup.1 is H or a hydrocarbyl group, R.sup.2 and R.sup.3 are each, independently, H or a hydrocarbyl group, R.sup.4 is a monovalent terminating group, each m is independently 0 or an integer ranging from 1 to about 10, x ranges from 0 to about 8, and each Z is independently OH, lower alkoxy, (OR.sup.5).sub.b OR.sup.6 or O.sup.- wherein each R.sup.5 is independently a divalent hydrocarbyl group, R.sup.6 is H or hydrocarbyl and b is a number ranging from 1 to about 30 and c ranges from 1 to about 3, y is a number ranging from 1 to about 10 and wherein the sum m+c does not exceed the number of valences of the corresponding Ar available for substitution and at least one A is independently an amide or an amid…
