Title (EN) DISPERSANTS DERIVED FROM HYDROXY FATTY ACID POLYESTERS AND POLYALKYLENE GLYCOL DISPERSANTS
(FR) DISPERSANTS DÉRIVÉS DE POLYESTERS D'ACIDES GRAS HYDROXYLÉS ET DISPERSANTS À BASE DE POLYALKYLÈNE GLYCOL
Abstract:
(EN) The disclosed invention relates to a dispersant composition comprising at least one block derived from (i) a polyester of a hydroxy substituted carboxylic acid and at least one block derived from (ii) a polyalkylene glycol terminated by a amine group or a hydroxyl group. The invention also provides lubricating compositions containing the described dispersant as well as methods of making and using the described dispersant, including method of making the dispersant, methods of lubricating an engine with a lubricant containing the described dispersant, and methods of reducing sludge formation in an engine.
(FR) La présente invention concerne une composition de dispersants contenant au moins une séquence dérivée (i) d'un polyester d'acide carboxylique à substitution hydroxy et au moins une séquence dérivée (ii) d'un polyalkylène glycol terminé par un groupe amine ou un groupe hydroxyle. L'invention concerne également des compositions de lubrification contenant le dispersant de l'invention, ainsi que des procédés de préparation et d'utilisation du dispersant de l'invention, notamment un procédé de préparation du dispersant, des procédés de lubrification d'un moteur avec un lubrifiant contenant le dispersant de l'invention et des procédés de réduction de la formation de dépôts dans un moteur.
