Abstract (en)
[origin: US4747964A] New dispersing additive compositions for lubricating oils, an object of the invention, have an improved efficiency. Said compositions may be either (1) the products obtained by reacting alkenylsuccinimides with aromatic dianhydrides, or (2) the products obtained by reacting alkenylsuccinimides with an anhydride or a dianhydride of mono- or poly-carboxylic aliphatic, alicyclic or aromatic acid of low molecular weight, the obtained product being then reacted with at least one organic compound having several hydroxyl and/or amine groups. These dispersing additive compositions may be added to lubricating oils in a proportion, for example, from 0.1 to 20% by weight.
