<p>Nitrogen-containing functionalised polymers may be obtained by reacting olefinically-unsaturated polymers and N-substituted amido or imido compounds in the presence of an acid catalyst. The compounds may be useful as oil additives, for example, as dispersants, in lubricating or fuel oil compositions. C2 to C25 olefins may be reacted with N-substituted amido or imido compounds to obtain dihydrooxazine compounds, which may be useful as chemical intermediates.</p> |
