  • Patent number: 5919869
    Abstract: 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 M.sub.n 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 H.sub.2 C.dbd.CHR.sup.4, wherein R.sup.4 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.

  • Patent number: 5906966
    Abstract: The present invention is based on the discovery that viscosification agents selected from sulfonated and neutralized sulfonated ionomers can be readily incorporated into oil-based drilling muds in the form of an oil soluble concentrate containing the polymer. Thus, one embodiment of the present invention provides an additive concentrate for oil-based drilling muds comprising a drilling oil, especially a low toxicity oil, and from about 5 gm to about 20 gm of sulfonated or neutralized sulfonated polymer per 100 gm of oil. Indeed, oil solutions obtained from the sulfonated and neutralized sulfonated polymers used as viscosification agents are readily incorporated into drilling mud formulations.

  • Patent number: 5783735
    Abstract: A process for preparing polymeric amides is disclosed. The process comprises sequentially reacting a hydrocarbon polymer functionalized (e.g., via the Koch reaction) to contain acid, ester, thioacid and/or thioester groups with a heavy polyamine to form a partially derivatized product in which at least about 85% of the functional groups are converted to heavy (thio)amide groups, and then reacting the partially derivatized product with an excess of light amine to complete the derivatization by converting substantially all of the remaining functional groups to light (thio)amide groups. Products of the foregoing process are also disclosed, which products are useful as additives in fuels and in lubricants.
