    Abstract: Polyolefins, paraffins and polar compounds containing a gemstructured hydrocarbon ''''backbone'''' are useful as traction fluids or as components of traction fluids. For example, compositions, useful as additives to libricants (e.g., components of traction fluids), are produced by oxonolysis of polyolefins, particularly of polyisobutylene oligimers containing at least one pair of maximally crowded geminal methyl groups. For example, ozonolysis of the novel polyisobutylenes can produce oxygenated derivatives (ketones, esters, acids, aldehydes, alcohols, etc.) which are useful as components of traction fluids. Blends of the ketones or of mixtures of the acids and ketones with a base oil (e.g., a paraffinic lube, naphthenic lube, a hydrogenated naphthenic or paraffinic lube, polyolefins or hydrogenated polyolefins) are especially useful as traction fluids or as a lubricant for a friction drive or a limited slip differential. Other polar compounds, useful as additives to lubricants or other mineral oil products (e.g., rubber process oils) can be obtained by conversion of polyisobutylene oligimers to polar compounds containing such functional groups as amine, imine, thioketone, amide, thioester, phosphate esters of the alcohols, ether, oxime, acyl halide, acyl hydrazide, chloride, bromide and maleic anhydride adducts. Salts of the carboxylic acids can also be useful as lubricant additives. A tin complex can also be made which has antiwear properties.

Gates, novel polyolefin and hydrogenated polyolefin oils are described which are useful as traction fluids, or as components of traction fluids. In particular, said application discloses oils consisting essentially of isobutene oligomers in the C.sub.12 -C.sub.48 carbon number range. The novel polyolefin oils or the individual olefins therein are also disclosed as being useful as chemical intermediates to prepare novel polar components (such as alcohols, acids, esters, ketones, thioketones, amides, amines, thioesters, phosphate esters of the alcohols and thioesters). The ketones, and other non-acidic ozonolysis products are disclosed as being useful as traction fluids or as components of traction fluids. Said application also contains a declaration that such derivatives, and their use as traction fluids or as antiwear additives in lubricants are the invention of Gary L. Driscoll and Marcus W. Haseltine, Jr., the present applicants.SUMMARY OF THE INVENTIONAn organo-tin compound, useful as an antiwear additive to a fuel or lubricant, is obtained by polymerization of isobutylene in the presence of stannic chloride. The antiwear additive can be recovered from such reaction products by such means as extraction with a solvent for the tin compound.Certain of the novel polyolefin oils of Ser. No. 52,301 consist essentially of "true isobutylene oligomers". Such oligomers are gem-structured, have crowded geminal methyl groups and are further described hereinafter. Substantially pure olefins of a single carbon number can be obtained as distillate fractions of such oils. The fractions or the oils are useful as lubricants (as for traction drives or for a controlled slip differential) and can be converted, by hydrogenation or other well known reactions, into gem-structured paraffins or polar compounds, which are useful as lubricants or components of blended lubricants.Such reactions are disclosed, for example, in the aforementioned applications Ser. No. 52,300; Ser. No. 52,301, Ser. No. 135,295; Ser. No. 137,556; Ser. No. 144,165 and Ser. No. 152,303.More generally, novel polyolefin oils of monomers of the formula: ##EQU1## wherein R is -CH.sub.3 and -C.sub.2 H.sub.5 and R.sub.1 is an alkyl group of from 1 to 10 carbon atoms, have exceptionally high viscosity indices and high coefficients of traction and consist essentially of unisomerized, true oligomers, such as true polyisobutylene oligomers (e.g., C.sub.16 H.sub.32, C.sub.20 H.sub.40, C.sub.24 H.sub.48 . . . . C.sub.48 H.sub.96). The novel oils are useful as electrical oils, as chemical intermediates or as tractants (i.e. as traction fluids or as components of traction fluids). The hydrogenated oils are novel and especially useful as tractants, particularly when hydrogenated to a bromine number less than 10 (more preferably, less than 5). The unique character of these novel oils, whether olefin and/or paraffin, can be proved by a combination of gas chromatography and nuclear magnetic reasonance spectroscopy (NMR). These olefins, and the paraffins produced by hydrogenation thereof, are characterized by "crowded" and sterically hindered geminal methyl and isolated methylene groups. The individual species in the range of C.sub.16 to C.sub.48 can be separated from the whole oil by vapor phase chromatography. One such novel polyolefin oil having an ASTM viscosity index greater than 85, consists essentially of monoolefins of carbon numbers C.sub.24, C.sub.28, C.sub.36 and C.sub.40 and having repeating isobutylene structures.In general, improved traction fluids and components of traction fluids can be obtained by putting a polar group on a gem-structured hydrocarbon (such as the gem-structured polyisobutylenes), preferably, the compound contains no aromatic or olefinic unsaturation. The resulting polar molecule appears to be more strongly attracted to metal surfaces (compared to the parent hydrocarbon) and thus produces higher traction. That such traction fluids exhibit high traction is unexpected since the literature (see Rounds, J. Chem. & Eng. Vol. 5 (No. 4) October, 1960, and included references) teaches that hydrocarbons containing polar groups on one end reduce the static and dynamic friction of mineral oils.For example, compounds which are useful as traction fluids or as components of traction fluids or other lubricants can be represented by the following structural formula: ##EQU2## wherein n is an integer from 1-30, n' is 0 or 1, R, R.sub.1 and R.sub.2 are one or a combination of the following radicals: methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tert-butyl, isopentyl, neopentyl, cyclohexyl, methylcyclohexyl, indanyl, hydrindanyl, cyclohexylindanyl, cyclohexyl hydrindanyl; and where Y would be any of the following functional groups: ketone, carboxylic acid, acid salts, ether, alcohol, ester, acyl halide, acyl hydrazide, mercaptan, epoxy, thioester, thiolester, thioether, phosphate (including coesters), phosphite (including coesters), sulfate, sulfite, sulfonate, halide, oxime, imine, amide, amine or maleic anhydride adduct. More than one functional group can be present in a given molecule (e.g. imine and amine). Also, the indanyl compounds and/or their cyclohexyl moieties, may be C.sub.1-6 lower alkylsubstituted, as for example, with a methyl group. Tin complexes, as hereinafter described, are also polar compounds within the scope of this invention. ##EQU3## where n, n' and Y are as previously described.Such polar compounds are particularly useful as tractants when added in major (e.g. 50-90 volume percent) quantities or minimum effective amounts (e.g. 1 percent, more preferably 3 percent, and typically at least 6 percent) to such as paraffinic lubes (preferably solvent refined and/or dewaxed), naphthenic lubes (preferably naphthenic acid free), polyolefin fluids and synthetic (e.g. see U.S. Pat. No. 3,287,259) naphthenic lubes. All of the above-referred to base oils can be partially or fully hydrogenated to improved chemical and/or thermal stability and to permit longer periods of high traction under use conditions. Particularly useful lubricants comprise such a hydrogenated base oil which contains less than 5 weight percent of gel aromatic compounds and less than 10 weight percent of olefins and which also contains from 0.520 percent of a gem-structured polar compound, preferably, corresponding to the above formula.In one embodiment, the present invention involves lubricant compositions comprising chemical compounds which can be produced by the action of various chemical reagents on the polyolefins or polyolefin oils. Similar reactions can be performed on other gem-substituted olefins to obtain the polar component of the present invention. Such compounds are useful as lubricant additives, particularly lubricants for tractive drives, friction drives and limited slip differentials.One typical toric traction transmission is that described in Hewko et al., "Tractive Capacity and Efficiency of Rolling Contacts," Proceedings of the Symposium on Rolling Contact Phenomena Elsevier Amsterdam, 1962, pp. 159-161.Circulation of the lubricant throughout the drive unit can be accomplished by spray lubrication or by splash effect. In a further embodiment, the lubricant is applied in mist or aerosol form. For mist lubrication, the lubricant can contain, to improve reclassification and/or reduce stray mist, an effective amount (e.g. 0.01-2 weight percent polymer) of a polymeric additive selected from one or a mixture of acrylic, methacrylic, olefin (e.g. isobutylene) and styrene (e.g. .alpha.-methylstyrene) polymers having a viscosity average molecular weight in the range of 10,000-2,000,000 (preferably 100,000 to 500,000). Such additives are described in the prior art. Of the above noted polar additives the more preferred are the polyolefins and the polar polyolefins (e.g. poly(methyl methacrylate)).The substituted polybutene components of the present invention are usually liquids and have good solubility in petroleum oils. Therefore, these derivatives can be especially useful as lubricant additives or as additives to other oils, or petroleum products (such as rubber process oils, hydraulic fluids, fuels, refrigeration oils, textile machinery lubricants, coolant for a nuclear reactor, paints, etc.). By choice of the molecular weight (or viscosity) of the polyolefin starting material, the derivatives can be "tailored" to a desired viscosity or molecular weight.DESCRIPTION OF THE DRAWINGThe accompanying drawing is typical of a vapor phase chromatogram, in the C.sub.16 -C.sub.32 region, of a novel polyisobutene oil of the present invention, and, by nearly baseline resolution (the broken line is the base line), indicates the very minor content therein of cracked, isomerized or other non-isobutene oligimer species. The vapor phase chromatogram of the same oil after hydrogenation will also be similar to that of the figure with respect to the virtual base line resolution.Each peak in the drawing is produced by a unique hydrocarbon species (e.g. C.sub.20), characterized by maximally "crowed" and sterically hindered geminal methyl and isolated methylene groups.Vapor phase chromatograms of commercially available polybutene oils show that such oils do not consist essentially of true oligimers of isobutene but contain appreciable amounts of virtually all of the carbon number species which could be present within the carbon number range of the oil. For example, a commercially available polybutene oil produced distinct VPC peaks within the C.sub.16-C.sub.29 range which could be identified as C.sub.16, C.sub.17, C.sub.19, C.sub.20 , C.sub.23, etc. This oil also had far from base line resolution (i.e. an "envelope"), thus, indicating the presence of many isomeric forms of the other possible carbon number species (e.g. C.sub.18, C.sub.22, C.sub.26).The novel polyisobutylene and hydrogenated polyisobutylene oils of the present invention have a higher viscosity index (usually at least 10 percent higher) than oils of the same viscosity at 210.degree.F prepared from polyisobutylene by prior art techniques. Although the present invention includes oils consisting essentially of isobutene oligimers in the C.sub.12 -C.sub.48 carbon number range, the more preferred polyisobutene oils described herein, have a viscosity index in the range of 90-130 (typically at least 95) and consist essentially of true polyisobutene oligimers in the 20-40 carbon number range. As used herein viscosity index (unless specified as "ASTM") refers to Viscosity Temperature Function Viscosity Index (VTF-VI) as determined by the technique of W. A. Wright as set forth in ASTM Bulletin No. 215, 84, (1956). This value is similar to that obtained by ASTM D 2270 which is reported herein as ASTM-VI.FURTHER DESCRIPTIONThe proper selection must be made of solvent and catalyst in order to produce oligimers of the olefin starting material with a minimum of the disproportionation and isomerization that are found in oils of the prior art processes. The solvent serves as a polar solvent to solvate the intermediate carbonium ions formed during the reaction, and to complex the catalyst to give a catalytically active species which remains in the solvent phase. The nitromethane and nitroethane also dissolves appreciable amounts of monomer but little of the oils. This last property is believed to be partly responsible for the narrow molecular weight distribution obtained in the product when using these preferred solvents, which results in a more favorable product distribution. Suitable solvents for meeting the requirements for this purpose have been found to be nitromethane, nitroethane, nitropropane, nitrobenzene, benzene, lower alkyl benzenes and mixtures thereof. Suitable lower alkyl benzenes include toluene, the xylenes and ethyl benzene. Of these nitro compounds are preferred (with nitroethane being the especially preferred solvent). Reasonable yields of polyisobutylene oils having KV.sub.210 =1.5-20 and VTF-VI=95-115 can be prepared.The preferred process for the preparation of these fluids involves the use of substantially anhydrous stannic chloride as catalysts and nitromethane (or nitroethane) as solvent. However, small amounts of water can act as reaction promoters.The catalyst used in the preferred process (for making oils having an average molecular weight up to about 1000) is stannic chloride. The stronger Lewis acid catalyst such as aluminum chloride, aluminum bromide, titanium tetrachloride and antimony pentachloride, do not cause any appreciable polymerization of the monomers in nitromethane. Boron trifluoride in nitromethane gives an oil product from isobutene having a viscosity index of about 75. Stannic chloride does not catalyze the polymerization of these monomers satisfactorily in such solvents as ether, water, dioxane, acetic acid, acetone, acetonitrile, acetic anhydride, diethylene glycol monoethyl ether, chloroform, methyl acetate, dimethoxyethane, N-methyl-pyrolidione, and hexamethylphosphormaide.This system is operated at low pressure near ambient temperature, gives high ratios of product to catalyst consumed, is highly selective for isobutylene while tolerating a wide variety of feed compositions, is easily controlled to give the desired products, and is well suited for continuous recycle operation.Product isolation involves simple phase separation. The product distribution is suffciently narrow that simple vacuum topping is required so no heavy by-products are formed. By-product dimer, trimer and tetramer have some commercial uses and are also readily cracked to isobutylene for recycle.The most important reaction variables are the temperature and the rate of feed relative to the amount of catalyst present (which determines the reaction rate).In general the temperature can be varied from -30.degree.C to +100.degree.C with from -30.degree.C to 50.degree.C being the preferred range 0.degree. to 35.degree.C being an especially preferred range. Electrical oils are generally obtained at lower temperatures than those used in obtaining tractants. The volume of oil prepared is generally at least equal to the volume of solvent for a given run but the ratio of volume of oil prepared to volume of solvent present may easily exceed 10:1. When carrying out the process in a continuous operation by continuously removing the reaction medium and separating the product from the catalyst and solvent; the ratio of solvent to product generally is maintained at from 2:1 to 1:2.The catalyst may be used in an amount equal from 0.1 to 40 volume percent of the solvent present, and preferably from 1 to 20 volume percent of the solvent present.The concentration of the free monomer in the reaction medium is relatively small and can be controlled by the pressure maintained at given temperature for gaseous feeds, and by rate of addition for liquid olefin feeds, thus, controlling the molecular weight of the product. Generally pressures of from about 1 to 275 psi absolute have been found most suitable with from 10 to 100 psia being the preferred range.The feed stock can vary from 5 to 100 percent vinylidene monomer (e.g. isobutylene), the remainder being any inert hydrocarbons. The presence of hydrocarbon non-vinylidene compounds is not detrimental since the vinylidene monomers as defined herein are selectively polymerized by the catalyst system. For instance, the efficiency of isobutene removal from mixtures of isobutene and other butenes and/or butanes depends on the particular process but is relatively insensitive to small amounts of impurities such as air, water, organo-sulfur or organo-nitrogen compounds.Distillation to produce different oil compositions can give varying results depending on the vacuum, the apparatus, the distillation rate and the composition of the reaction product which is distilled. Under some conditions, considerable (>15%) trimer can be left when the oil is topped to 80.degree.C, under other conditions little (
