Abstract
It has been found that products made by reacting a polyalkenylsuccinic compound with an aromatic secondary amine or hindered phenol containing a hydroxyalkyl group, followed by reaction with an alkanolamine or an aminomethane, give a novel additive having utility as a dispersant and/or an anticorrosion agent when placed in a lubricant.
