Abstract

Additives of low and high molecular weight used as performance enhancers in engine oil formulations can interact through their polar functional groups to form associates and complexes. These often have a significant thickening effect that could substitute for viscosity and viscosity-index improvers. We therefore investigated the stability of these associates to thermal degradation, oxidation, and mechanical decomposition, in an attempt to seek information about their feasibility.
