ABSTRACT:
A lubricant additive composition and method for production is disclosed comprising the adduct of an olefinic oligomer and an enophile, said olefinic oligomer comprising the product of the oligomerization of C.sub.2 to C.sub.24 alpha-olefin feedstock, or mixtures thereof, under oligomerization conditions in contact with a reduced valence state Group VIB metal catalyst on porous support. Maleic anhydride is a preferred enophile. The maleic anhydride adduct is reacted with polyamines such as tetraethylene pentamine to form the corresponding alkenyl bis-succinimide.
