Oil soluble dispersant additives modified with monoepoxy monounsaturated compounds

摘要

An oil soluble dispersant comprising the reaction products of: (1) at least one of (i) oil soluble salts, amides, imides, oxazolines, esters, or mixtures thereof of long chain hydrocarbyl substituted mono- and dicarboxylic acids or their anhydrides or esters, (ii) long chain hydrocarbon having a polyamine attached directly thereto, and (iii) long chain hydrocarbyl-substituted Mannich condensation products containing at least one reactive group selected from reactive amino groups and reactive hydroxyl groups; and (2) at least one monoepoxide monounsaturated linking reactant.
