Polymers having terminal hydroxyl, aldehyde, or alkylamino substituents and derivatives thereof |
摘要 |
A polymer having a terminal hydroxyl, aldehyde or alkylamino substituent which may be used directly or in a derivative form as a dispersant for both fuel and lubricating oil compositions, wherein the polymer has a Mn of about 300 to 10,000, and is derived from a polyolefin which is derived from a polyene (diene, e.g.), monomer of the formula H2C=CHR4, wherein R4 is hydrogen or a straight or branched chain alkyl radical. Preferably, the polyolefin has at least about 30% terminal vinylidene unsaturation. Particularly desirable amine derivatives can be formed by either a single step aminomethylation process or a two step hydroformylation and reductive amination process.
