Process for making a polyalkenyl derivative of an unsaturated acidic reagent |
摘要 |
<p>A polyalkenyl derivative of an unsaturated acidic reagent prepared by the process of reacting a polyalkene having a Mn of at least 300 with an unsaturated acidic reagent at elevated temperatures in the absence of a strong acid until at least 25% of the polyalkene is converted to a polyalkenyl derivative of an unsaturated acidic reagent, continuing the reaction of the polyalkene with an excess of the unsaturated acidic reagent at elevated temperatures in the presence of a strong acid to convert at least some of the unreacted polyalkene to additional polyalkenyl derivative of an unsaturated acidic reagent, and removing the unreacted unsaturated acidic reagent.</p> |
