摘要：
There are disclosed macrocyclic and polycyclic polyamine lubricating oil additives formed by acylation of macrocyclic polyamines with hydrocarbon susbstituted succinic anhydride or carboxylic acids. These compounds are useful as dispersants and dispersants-V.I. improvers in both gasoline and diesel engine lubricating oil compositions and are also useful fuel additives.
