ABSTRACT:
Compositions useful as multi-purpose lubricant and functional fluid additives and as thickeners and antisag 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.
