Production of borated ashless dispersants

A borated reaction product that is useful as a dispersancy enhancing lubricant additive. The product is produced from the maleic anhydride adduct of an olefinic alpha-olefin oligomer. The oligomer (HVI-PAO) comprises the product of the oligomerization of C2 to C24 alpha-olefin using a reduced valenc...

Zusammenfassung:	A borated reaction product that is useful as a dispersancy enhancing lubricant additive. The product is produced from the maleic anhydride adduct of an olefinic alpha-olefin oligomer. The oligomer (HVI-PAO) comprises the product of the oligomerization of C2 to C24 alpha-olefin using a reduced valence state Group VIB metal as the oligomerization catalyst. This adduct of maleic anhydride and HVI-PAO is reacted with a secondary amine such as diphenylamine, an alkanol amine such as triethanolamine, and a borating agent such as boric acid or a borate ester.
