Polymeric dispersants having polyalkylene and succinic groups |
| 摘要 |
<p>Novel copolymers of unsaturated acidic reactants and high molecular weight olefins are useful as dispersants in lubricating oils and fuels and also may be used to prepare polysuccinimides and other post-treated additives useful in lubricating oils and fuels. The ratio of anhydride groups to the hydrocarbon groups in these novel copolymers is at least 1.3.</p> |
