MULTIFUNCTIONAL VISCOSITY MODIFIERS WITH IMPROVED DISPERSANCY AND ANTIOXIDANCY DERIVED FROM ADDUCTS OF QUINONE |
摘要 |
An oil-soluble lubricating oil and fuel additive, useful as a multifunctional viscosity modifier comprising succinimide and other amine-containing polymers reacted with a quinone or substituted quinone adducts. Suitable polymers are those containing primary or secondary amine groups such as EPSA-PAM and EPDM-amine polymers. The multifunctional viscosity modifier additive provides improved dispersancy and antioxidancy to a lubricating oil or fuel composition. |
