摘要:
The present invention is directed to oil-soluble lubricating oil viscosity index improver/dispersant additives comprising Mannich Base condensates of a grafted ethylene copolymer, an optionally alkyl-substituted N-hydroxyaryl compound, an aldehyde, and a monosecondary amine, whereby oil solutions, particularly oil concentrates, of said additives which are characterized by minimal viscosity change over an extended period of time. These additives comprise a copolymer of ethylene with one or more C.sub.3 to C.sub.28 alpha-olefins, preferably propylene, which have been grafted with acid moieties, e.g. maleic anhydride, preferably using a free radical initiator in a solvent such as a lubricating oil, which is then either (a) reacted with an N-hydroxyaryl amine and then condensed with an aldehyde and a monosecondary amine to form the Mannich Base viscosity index improver/dispersant material, or (b) reacted with a preformed Mannich Base condensate of an N-hydroxyaryl amine, aldehyde and the monosecondary amine. The invention also relates to process for preparing the preceding products and their use in oil compositions.

The present invention is directed to an oil-soluble lubricating oil additive comprising at least one terminally unsaturated ethylene/alpha-olefin/diene interpolymer of 300 to 20,000 number average molecular weight substituted with mono- or dicarboxylic acid producing moieties (preferably dicarboxylic acid or anhydride moieties), wherein the terminal unsaturation comprises terminal ethenylidene unsaturation. The mono- and dicarboxylic acid or anhydride substituted interpolymers of this invention are useful per se as additives to lubricating oils, and can also be reacted with a nucleophilic reagent, such as amines, alcohols, amino alcohols and reactive metal compounds, to form products which are also useful lubricating oil additives, e.g., as dispersants.
