摘要：Condensation products made by reacting an &agr;-hydroxyalkyl hydroxy-aromatic compound also having at least one non-fused hydrocarbyl substituent with atleast one olefinic nitrile, carboxylic acid or carboxylic acid derivative are useful as additivesfor fuels and lubricants. The total number of carbon atoms in the non-fused hydrocarbylsubstituents is at least about 7 while the &agr;-hydroxyalkyl group contains from 1 toabout 36 carbons and the olefinic acid or nitrile reactant usually contains 2 to about 40carbon atoms. Products made from hydroxymethyl alkyl-substituted phenols and&agr;,&bgr;-olefinic acid derivatives such as maleic anhydride are particularly useful.Similarly useful post-treated products can be made from these condensation productsby further reaction with alcohols, amines, metal salts or metals.
