<p>Polyalkenylsuccinimide-maleic anhydride reaction products are used as effective antifoulants in a liquid hydrocarbonaceous medium, during processing of such liquids at elevated temperatures. The reaction products can be formed via a two-step reaction in which a polyalkenylsuccinic anhydride precursor is reacted with an amine to form polyalkenylsuccinimide intermediate which, in turn, is reacted with maleic anhydride.</p> |
