In accordance with the present invention, there is provi- ded a composition comprising the reaction product of par- ticular (1).alpha.,.beta.-unsaturated dicarboxylic acid esters and (2) olefinically unsaturated compounds, wherein the resulting com- position comprises a substantial amount of an intermediate molecular weight reaction product which is neither the well- known lower molecular weight alkenyl or alkyl succinic reac- tion product, nor the well-known polymerization reaction product, of (1) and (2). The compositions of the present invention are particularly suitable for use as lubricants and lubricant additives. In accordance with the present invention, there is also provided a process for the preparation of such compositions suitable for use as a lubricant or lubricant additive wherein components (1) and (2) axe reacted in the presence of an effective amount of a polymerization inhibitor and/or in the absence of oxygen.
