摘要:
There are disclosed macrocyclic and polycyclic polyamine lubricating oil additives formed by cyclodehydration of reaction products of hydrocarbon substituted succinic anhydrides or carboxylic acids with poly 3-amino propyl compounds or by acylation of macrocyclic polyamines and polycyclic polyamines with hydrocarbon substituted 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.
