POLYMERIC DISPERSANTS VIA NOVEL TERPOLYMERS

摘要

Novel terpolymers are disclosed which comprise the reaction product of a high molecularweight olefin, such as polybutene or polypropylene, with an unsaturated acid reactant, such asr[err]aleic anhydride and a di-or polyunsaturated reactant The terpolymers are useful as dispersantsin lubricating oils and fuels and are also used to prepared polysuccinimides and other post-treatedadditives useful in lubricating oils and fuels.
