Title
(EN) ASHLESS DISPERSANTS
(FR) DISPERSANTS SANS CENDRES
Abstract
(EN) According to the present invention, improved dispersants are provided which comprise adducts of (A) polymer-substituted mono- and dicarboxylic acid or anhydrides and (B) bis(para-amino cyclohexyl) methane oligomers, wherein the reactants are contacted in a reaction zone in the substantial absence of polar organic solvents.
(FR) Dispersants améliorés comprenant des produits d'addition de (A) anhydrides ou acide mono- et dicarboxylique à substitution de polymère, et (B) d'oligomères de di(para-amino cyclohexyl) méthane, dans lesquels les réactifs entrent en contact dans une zone de réaction pratiquement en l'absence de solvants organiques polaires.
