Polyalkenyl succinimides and use thereof as detergents for fuels |
abstract |
Polyalkenyl succinimides which can be obtained with a process which comprises: a. reacting a reactive low molecular weight polyalkene with maleic anhydride at a temperature higher than 180 °C; b. carrying out the reaction thermally for a time sufficient for having a conversion of the terminal vinylidene groups higher than 10%; c. completing the thermal reaction in the presence of a reaction accelerator consisting of a Lewis acid; d. reacting the reaction product of step (c) with an amine which has at least one primary aminic group capable of forming an imide group. |
