ETHYLENE/ALPHA-OLEFIN/DIENE INTERPOLYMER-SUBSTITUTED CARBOXYLIC ACID DISPERSANT ADDITIVES |
| 摘要 |
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 <u>per se</u> 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. |
