Abstract

Polyisobutylene (PIB)-succinic-anhydrides were synthesized from commercially available PIB with different molecular weight and reactivity. Then mono-, bis-, and polysuccinimides were synthesized from these intermediate products. The reactivity of the PIB determined the conversion and the properties of the intermediate products. There was no difference realized in the performances of the polysuccinimides based on the two higher reactivity PIB in engine oil formulas. The effectiveness of the polysuccinimide synthesized from the lower reactivity PIB was significantly worse. With low reactivity PIB because of the lower conversion ratio, the finished products would have lower efficiency. This kind of finished product could be used in places where a lower performance level was required (formulation of lower performance level engine oils) and where the non-reacted PIB had an advantageous effect like in 2T applications-combustion improvement. This is an abstract of a paper presented at the 15th International Colloquium Tribology - Automotive and Industrial Lubrication (Ostfildern, Germany 1/17-19/2006).
