Beschreibung
Zusammenfassung:	Disclosed is an oil soluble polyester composition, suitable for use as a dispersant in lubricating oils. The oil soluble polyester composition is prepared by reacting (a) a hydrocarbyl -substituted succinic acylating agent and (b) a di- hydroxyalkyl-substituted tertiary amine compound selected from a N,N'-di- hydroxyalkyl-substituted tertiary monoamine and a N,N'-di-hydroxyalkyl-substituted tertiary diamine. L'invention concerne une composition de polyester soluble dans l'huile pouvant être utilisée comme agent dispersant dans des huiles lubrifiantes. La composition de polyester soluble dans l'huile est préparée en faisant réagir (a) un agent d'acylation succinique à substitution hydrocarbyle et (b) un composé d'amine tertiaire à substitution dihydroxyalkyle choisi parmi une monoamine tertiaire à substitution N,N'-dihydroxyalkyle et une diamine tertiaire à substitution N,N'-dihydroxyalkyle.
