Adducts of quinone compounds and amine-containing polymers for use in lubricating oils and in fuels

A process for producing a composition useful as a fuel additive or lubricating oil additive comprising the steps of:

• (A) providing at least one quinone compound having at least one hydrogen on the quinone ring;
• (B) providing an amine-containing polymer having within its structure at least one reactive amino group selected from the group consisting of primary amino groups, secondary amino groups and mixtures thereof, wherein the amine-containing polymer comprises a Mannich condensation product of at least one alkyl substituted hydroxy aromatic compound formed by the alkylation of a hydroxy aromatic compound with a hydrocarbon polymer having a number average molecular weight of from about 300 to 20,000, an aldehyde reactant, and an amine compound having at least two reactive amino groups selected from the group consisting of primary amino groups, secondary amino groups, and mixtures thereof;
• and
• (C) contacting the quinone compound with the amine-containing polymer under conditions and for a time sufficient to react the quinone compound with at least a portion of the reactive amino groups to form a product mixture containing an oil soluble adduct of the quinone compound and the amine-containing polymer.
