Polymeric dispersants via novel terpolymers |
摘要 |
Novel terpolymers are disclosed which comprise the reaction product of a high molecular weight olefin, such as polybutene or polypropylene, with an unsaturated acid reactant, such as maleic anhydride and a di-or polyunsaturated reactant. The terpolymers are useful as dispersants in lubricating oils and fuels and are also used to prepared polysuccinimides and other post-treated additives useful in lubricating oils and fuels.
