ABSTRACT OF THE DISCLOSURE A composition comprising at least one compound of the general formula Image (I) 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, R1 is H or a hydrocarbyl group, R2 and R3 are each, independently, H or a hydrocarbyl group, R4 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, (OR5)bOR6 or O- wherein each R5 is independently a divalent hydrocarbyl group, R6 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 a group characterized by the formula Image (II) wherein Rb, Rc, Rd and Re are each independently H, hydroxyhydrocarbyl or hydrocarbyl groups, X is O, S or NRa wherein Ra is H, hydrocarbyl, hydroxyhydrocarbyl, aminohydrocarbyl or a group of the formula ?Y?aR5-D (III) wherein each Y is a group of the formula -R5-?- or -R5O- each R5 is a divalent hydrocarbyl group, each R7 is H, alkoxyalkyl, hydroxyalkyl, a hydrocarbyl group, an aminohydrocarbyl group, or an N-alkoxyalkyl- or hydroxyalkyl- substituted aminohydrocarbyl group, a is 0 or a number ranging from 1 to about 100 and D is a group of the formula Image (IV) In one embodiment, (I) is present in fuel compositions. In another embodiment it is used in lubricating oil compositions.
