ABSTRACT:
A lubricating oil soluble compound suitable for use as a dispersant additive is obtainable by reacting at elevated temperature a polyacrylate with a dispersant having at least one reactive nitrogen--containing moiety.
Intermediates of the general formula IV ##STR1## where Y.sup.1 is a group derived from the reaction of the polyacrylate with the reactive nitrogen-containing moieties (i.e. primary or secondary amine) 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.
