摘要:
Antioxidant-containing viscosity index (VI) improvers for high temperature service are disclosed and claimed. These viscosity index improvers are particularly useful at high temperature. Therefore, they are particularly useful with lubricating oils used in diesel engines.

Polymers containing post-reacted hindered phenol anti-oxidant functionality as viscosity index (VI) improvers for high temperature service, particularly for lubricating oils used in diesel engines.
摘要:
Polymers containing anti-oxidant functionality have been found to be useful as viscosity index (VI) improvers for high temperature service. The anti-oxidant moiety prevents extensive oxidative decomposition of the polymer making the polymers particularly useful with lubricating oils used in diesel engines.
