摘要:
A saturated polymer having a terminal aldehyde or hydroxy substituent which may be used directly or in a derivative form as a dispersant for both fuel and lubricating oil compositions, wherein the saturated polymer has a M.sub.n of about 300 to 10,000, and is derived from a polyolefin which is derived from a monomer of the formula H.sub.2 C.dbd.CHR.sup.4, wherein R.sup.4 is hydrogen or a straight or branched chain alkyl radical, and wherein 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.
