ABSTRACT:
Compositions useful as multi-purpose lubricant and functional fluid additives and as thickeners and anti-sag additives for resins, paints and the like are prepared by free radical polymerization of at least one ethylenically unsaturated monomer in the presence of an oil-soluble dispersant. The carboxylic dispersants are preferred, especially esters of hydrocarbon-substituted succinic acids wherein the substituent contains at least about 30 carbon atoms and the reaction products of such acids or their derivatives with amines, usually polyalkylene polyamines.
