ABSTRACT:
A lubricating oil soluble compound suitable for use as a dispersant additive is obtainable by reacting at elevated temperature an epoxyacrylate with a dispersant having at least one reactive nitrogen-containing moiety.
Intermediates of the general formula IV ##STR1## where Y' is a group derived from the reaction of the epoxyacrylate with reactive nitrogen-containing moieties (ie primary or secondary amines) are novel.
The process for preparing the lubricating oil soluble compounds can be a one step or multistep process.
Lubricating oil compositions comprise a major proportion of lubricating oil and a minor proportion of the lubricating oil soluble compounds.
