摘要:

AbstractAshless dispersants of the type of alkenyl‐succinic anhydride derivatives were prepared. The resistance of these compounds to oxidation and thermal decomposition was investigated by thermoanalytical methods. Results were compared to those obtained in a panel coking test of these additives at 300°C in a multifunctional package. It was found that data obtained by DSC could be used for rating the stability of polyisobutenyl‐succinimides against thermo‐oxi
