An oligomer from diarylamines is disclosed which has desirable antioxidant properties in lubricating oils which contain synthetic ester lubricants. The oligomer is desirable for use at higher temperatures where it has less volatility than simple diarylamines. The oligomer has substantial portions of monosubstituted diphenylamine repeat units which result in linear oligomers. Di and polysubstitued diphenylamines may optionally be present as repeat units. These di and polysubstituted diphenylamines generally react as monofunctional reactants in oligomerization and tend to reduce the number of repeat units in the average oligomer.
Oligomère de diarylamine ayant de bonnes propriétés antioxydantes pour les huiles lubrifiantes contenant des lubrifiants synthétiques à base d'esters. Il est souhaitable d'employer l'oligomère à haute température, où il est moins volatil que les diarylamines simples. L'oligomère comporte des parties importantes d'éléments de répétition de diphénylamines monosubstituées donnant lieu à des oligomères linéaires. Des diphénylamines di et polysubstituées peuvent éventuellement servir d'éléments de répétition. Ces diphénylamines di et polysubstituées, qui réagissent généralement comme des réactifs monofonctionnels lors de l'oligomérisation, ont tendance à réduire le nombre d'éléments de répétition dans l'oligomère moyen.
