Hydroxylalkyl hydroxy-aromatic condensation products as fuel and lubricant additives

Claim 1

An additional concentrate comprising about 20 to 90 percent of a condensation product made by the process comprising reacting (A) at least one alpha hydroxyalkyl hydroxy-aromatic compound of the general formula ##STR22## wherein Ar is a hydrocarbyl aromatic nucleus of 6 to about 30 carbon atoms, said aromatic nucleus substituted with 1 to 3 lower alkoxy, lower alkylthio, chloro, or nitro substituents, each R is a nonfused hydrocarbyl group of about 25 to about 700 carbon atoms, each R' is independently a hydrogen atom, an alkyl group of 1 to 36 carbon atoms, or a halogen-substituted alkyl group of 1 to about 36 carbon atoms, n is 1 to 3 and m is 1 to 5 with the provisos that (i) the total number of carbon atoms in the R' groups does not exceed 36 and (ii) where m exceeds 1, one of the R groups can also be a ##STR23## with (B) at least one hydrocarbyl, alpha-beta olefinically unsaturated compound selected from the group consisting of C 2-40 nitriles, and ammonium and metal salts of C 2-40 carboxylic acids, the reaction of (A) with (B) resulting in the formation of a carbon-to-carbon bond, said bond including the carbon of at least one ##STR24## and an inert solvent/diluent.
