AbstractCompositions useful as lubricant and fuel dispersants are prepared by reacting a hydroxyaromatic compound containing an aliphatic or alicyclic substituent which has at least about 6 carbon atoms with an aldehyde in the presence of an alkaline reagent and at a temperature up to about 125°C., substantially neutralizing the resulting intermediate at a temperature up to about 150°C., and then reacting with a primary or secondary amino compound.
