Abstract
Abstract Reaction products prepared by reacting (a) interpolymers of ethylene, one or more C 3 -C 8 α-monoolefins, and one or more polyenes selected from non-conjugated dienes and trienes, with (b) one or more olefinic carboxylic acid acylating agents to form an acylating reaction intermediate which is further reacted with (c) an amine, are disclosed. These reaction products have been found useful as multi-functional additives to a variety of lubricating oils for enhancing their dispersancy as well as improving their viscosity-temperature relationship.
