摘要:
Improved additives/dispersants for lubricant and fuel compositions are obtained by condensing a hydroxyalkyl or hydroxyaryl compound with an amine compound. The condensates according to the present invention are produced by the acid catalyzed condensation of the amine reactant with the hydroxy reactant.
