A hydrocarbyl-substituted mono- and bis-succinimide having polyamine chain linked hydroxyacyl radicals represented by the formula: <IMAGE> in which R is a hydrocarbyl radical having from about 8 to 400 carbon atoms, X is a divalent alkylene or secondary hydroxy-substituted alkylene radical having from 2 to 3 carbon atoms, A is hydrogen or a hydroxyacyl radical from the group consisting of glycolyl, lactyl, 2-hydroxymethyl propionyl and 2,2'-bis-hydroxymethyl propionyl radicals and in which at least 30 percent of said radicals represented by A are said hydroxyacyl radicals, x is a number from 1 to 6, and R' is a radical selected from the group consisting of -NH2, -NHA, or a hydrocarbyl substituted succinyl radical having the formula: <IMAGE> in which R and A have the values noted above, and a hydrocarbon oil composition containing same are provided. |
