ABSTRACT OF THE DISCLOSURE Condensation products made by reacting an alpha-hydroxyalkyl hydroxy-aromatic compound also having at least one non-fused hydrocarbyl substituent with at least one olefinic nitrile, carboxylic acid or carboxylic acid derivative are useful as additives for fuels and lubricants. The total number of carbon atoms in the non- fused hydrocarbyl substituents is at least about seven while the alpha-hydroxyalkyl group contains from one to about 36 carbons and the olefinic cold or nitrile reactant usually contains two to about forty carbon atoms. Pro- ducts made from hydroxymethyl alkyl-substitued phenols and .alpha.,.beta.-olerfinic acid derivatives such a maleic anhydride are particularly useful. Similarly useful post-treated pro- ducts can be made from these condensation products by further reaction with alcohols, amines, metal salts or metals.
