Definitions
- the invention relates to the use of an esterified copolymer to improve high-temperature high-shear performance of a lubricating oil for a driveline device.
- Viscosity modifiers also known as viscosity index (VI) improvers
- VI viscosity index improvers
- the viscosity modifier is combined, in the lubricating oil composition, with a base oil, together with other performance additives, such as dispersants, detergents, friction modifiers, corrosion inhibitors, pour point depressants, and so forth, depending on the particular application.
- Typical viscosity modifiers include polymers of alkyl methacrylates, alkyl acrylates, olefins (such as copolymers of ethylene and propylene), copolymers of styrene and conjugated dienes, and copolymers of maleic anhydride with alpha-olefins or styrene, and their esterified derivatives.
- Viscosity modifiers comprising ester groups tend to incorporate ester functional groups in pendent/grafted/branched groups.
- the ester functional groups may be derived from linear or branched alkyl alcohols with 1 to 40 carbon atoms. Examples of such polymers are disclosed in U.S. Patent Nos. 5,435,928 ; 6,174,843 ; 6,419,714 ; 6,544,935 ; and 7,254,249 ; and International Application Nos. WO 07/133999 and WO 2010/014655 .
- Lubricating oils are often subjected to high temperatures and high shear conditions. Under certain conditions, a viscosity modifier can be mechanically degraded by the moving parts and partially lose its ability to increase the viscosity of the base oil. The degradation causes lowered lubricant film thickness, which can, in turn, lead to accelerated wear.
- the shear stability of viscosity modifiers tends to increase as the molecular weight decreases. However, the thickening capability of the viscosity modifier also decreases as the molecular weight decreases.
- Compositions have been formulated to achieve minimum high temperature/high shear rate (HTHS) viscosity to protect against excessive wear in various areas of an automobile, such as driveline devices and in the engine.
- HTHS viscosity lubricating compositions although good for wear protection, tend to suffer from poor fuel economy.
- fluids with relatively low HTHS viscosities typically also exhibit low kinematic viscosity (KV), resulting in formation of a thinner lubricating film, which can improve fuel economy but negatively impact wear protection.
- KV kinematic viscosity
- the present invention concerns the use of an esterified copolymer to improve high-temperature high-shear (HTHS) performance measured according to ASTM D4683-10 of a lubricating oil, the esterified copolymer including a polymeric backbone comprising at least 60% of units (A1) derived from a vinyl monomer and units (A2) derived from a carboxylic acid monomer, wherein the ratio of (A1) to (A2) is from 1:3 to 3:1, the vinyl monomer comprising a vinyl aliphatic monomer, the carboxylic acid monomer comprising an ethylenically unsaturated carboxylic acid or derivative thereof, esterified with a primary alcohol, and no more than 30 mole% of units derived from one or more monomers capable of polymerizing with one or both of the vinyl monomer and carboxylic acid monomer, in a lubricating oil for a driveline device.
- HTHS high-temperature high-shear
- the use is to improve kinematic viscosity performance measured according to ASTM D445 of the lubricating oil as temperature increases. In one embodiment the use is to improve kinematic viscosity performance measured according to ASTM D445 of the lubricating oil as shear rate increases.
- a method for determining viscosity index (VI) of a lubricating composition is according to the procedure outlined in ASTM D2270, "Standard Practice for Calculating Viscosity Index From Kinematic Viscosity at 40 and 100°C," ASTM International, West Conshohocken, PA, DOI: 10.1520/D2270-10E01 .
- KV The kinematic viscosity
- a method for determining the High Temperature High Shear (HTHS) viscosity of a lubricating composition is according to the procedure ASTM D4683-10, "Standard Test Method for Measuring Viscosity of New and Used Engine Oils at High Shear Rate and High Temperature by Tapered Bearing Simulator Viscometer at 150 °C," ASTM International, West Conshohocken, PA.
- This test method determines the viscosity of an oil at 150 °C and 1.0.10 6 s -1 using a viscometer having a slightly tapered rotor and stator called the Tapered Bearing Simulator (TBS) Viscometer.
- Alternate methods for measuring HTHS viscosity include the Tapered Plug Viscometer (TPV, ASTM D4741) and the high pressure capillary viscometer (ASTM D5481).
- the lubricating composition can have a ratio of kinematic viscosity (KV_100) to HTHS of up to 2.6-3.6.
- the viscosity at low temperatures can be measured using the Brookfield Viscosity method as described in ASTM method D2983-09, "Standard Test Method for Low-Temperature Viscosity of Lubricants Measured by Brookfield Viscometer.” According to SAE J306, "Automotive Gear Lubricant Viscosity Classification,” for SAE 75W automotive gear oils, the maximum viscosity measured at -26°C is also 150,000 cP.

The application allows for multiple temperatures and shear rates to be assigned, but as stated individual temperatures and shear rates are used. Once the temperature and shear rate profile has been loaded, the new sample is loaded. Numerous flushing steps of the current test fluid are required before the sample (0.5 mL) is loaded into the test chamber. Once loaded and set to run, the motor and flywheel are set to spin to provide the appropriate shear rate. A clutch engages the rotor and three pulses, approximately five second apart, are applied to the sample. The viscosity is determined by calculating the average of the resistance on the rotor.

Description
- The invention relates to the use of an esterified copolymer to improve high-temperature high-shear performance of a lubricating oil for a driveline device.
- Viscosity modifiers (also known as viscosity index (VI) improvers) are often added to lubricating oil compositions to improve the viscosity index of the lubricant. The viscosity modifier is combined, in the lubricating oil composition, with a base oil, together with other performance additives, such as dispersants, detergents, friction modifiers, corrosion inhibitors, pour point depressants, and so forth, depending on the particular application. Typical viscosity modifiers include polymers of alkyl methacrylates, alkyl acrylates, olefins (such as copolymers of ethylene and propylene), copolymers of styrene and conjugated dienes, and copolymers of maleic anhydride with alpha-olefins or styrene, and their esterified derivatives. Viscosity modifiers comprising ester groups tend to incorporate ester functional groups in pendent/grafted/branched groups. The ester functional groups may be derived from linear or branched alkyl alcohols with 1 to 40 carbon atoms. Examples of such polymers are disclosed in
U.S. Patent Nos. 5,435,928 ;6,174,843 ;6,419,714 ;6,544,935 ; and7,254,249 ; and International Application Nos.WO 07/133999 WO 2010/014655 . - Lubricating oils are often subjected to high temperatures and high shear conditions. Under certain conditions, a viscosity modifier can be mechanically degraded by the moving parts and partially lose its ability to increase the viscosity of the base oil. The degradation causes lowered lubricant film thickness, which can, in turn, lead to accelerated wear. The shear stability of viscosity modifiers tends to increase as the molecular weight decreases. However, the thickening capability of the viscosity modifier also decreases as the molecular weight decreases.
- Compositions have been formulated to achieve minimum high temperature/high shear rate (HTHS) viscosity to protect against excessive wear in various areas of an automobile, such as driveline devices and in the engine. High HTHS viscosity lubricating compositions, although good for wear protection, tend to suffer from poor fuel economy. By contrast, fluids with relatively low HTHS viscosities typically also exhibit low kinematic viscosity (KV), resulting in formation of a thinner lubricating film, which can improve fuel economy but negatively impact wear protection.
- So for either enhanced wear protection, or for improved fuel efficiency, it is advantageous for the ratio of HTHS/KV to be as high as possible. With this relationship it would be possible to formulate, 1) lubricating oils with the same KV but higher HTHS, or in other words, to have the same fuel efficiency but improved wear protection, 2) lubricating oils with the same HTHS but reduced KV, i.e. the same wear protection but improved fuel efficiency, and 3) reduce KV but increase HTHS.
- It would be desirable to provide a lubricating composition that provides good HTHS and shear stability for durability while providing a low kinematic viscosity to reduce friction and improve fuel economy.

- In one embodiment the use is to improve kinematic viscosity performance measured according to ASTM D445 of the lubricating oil as temperature increases. In one embodiment the use is to improve kinematic viscosity performance measured according to ASTM D445 of the lubricating oil as shear rate increases.
- A method for determining viscosity index (VI) of a lubricating composition is according to the procedure outlined in ASTM D2270, "Standard Practice for Calculating Viscosity Index From Kinematic Viscosity at 40 and 100°C," ASTM International, West Conshohocken, PA, DOI: 10.1520/D2270-10E01.
- The kinematic viscosity (KV) is according to ASTM D445. The KV can be expressed as KV_100 or KV_40 (KV refers to Kinematic Viscosity, and 100 or 40 refers to the Celsius temperature at which the viscosity of the oil is measured). Unless otherwise noted, KV values are determined by this method and are reported in Centistokes (cSt). 1 cSt = 1 mm2/s.
- A method for determining the High Temperature High Shear (HTHS) viscosity of a lubricating composition is according to the procedure ASTM D4683-10, "Standard Test Method for Measuring Viscosity of New and Used Engine Oils at High Shear Rate and High Temperature by Tapered Bearing Simulator Viscometer at 150 °C," ASTM International, West Conshohocken, PA. This test method determines the viscosity of an oil at 150 °C and 1.0.106 s-1 using a viscometer having a slightly tapered rotor and stator called the Tapered Bearing Simulator (TBS) Viscometer. Alternate methods for measuring HTHS viscosity include the Tapered Plug Viscometer (TPV, ASTM D4741) and the high pressure capillary viscometer (ASTM D5481).
- For some applications, the lubricating composition can have a ratio of kinematic viscosity (KV_100) to HTHS of up to 2.6-3.6.
- The viscosity at low temperatures can be measured using the Brookfield Viscosity method as described in ASTM method D2983-09, "Standard Test Method for Low-Temperature Viscosity of Lubricants Measured by Brookfield Viscometer." According to SAE J306, "Automotive Gear Lubricant Viscosity Classification," for SAE 75W automotive gear oils, the maximum viscosity measured at -26°C is also 150,000 cP.
- The inventors have found that an esterified copolymer according to embodiments of the invention can provide a lubricant with at least one (or at least two, or all) of acceptable or improved HTHS, KV, shear stability, acceptable or improved viscosity index control, and acceptable or improved low temperature viscosity.

The esterified copolymer is formulated to provide the lubricating composition with a high ratio of high temperature/high shear rate (HTHS) to kinematic viscosity (KV). The resulting lubricating composition can have improved wear protection while providing low kinematic viscosity for improved fuel efficiency.

- An exemplary lubricating composition can include from 0.1 to 50 wt. %, or 1.0 to 20 wt. %, or 1.5 to 10 wt. % of the exemplary viscosity modifier, such as less than 5 wt. % of the viscosity modifier.

The vinyl monomer comprises a vinyl aliphatic monomer. Exemplary aliphatic vinyl monomers include alpha-olefins. By way of example, the exemplary copolymer can include a polymeric backbone derived from 1-dodecene and maleic anhydride, as the carboxylic acid monomer.
- In the exemplary copolymer, at least 70%, or at least 80%, or at least 90%, or at least 95%, such as 70%-95%, and up to 100% of the units in the backbone, is derived from the vinyl monomer and the carboxylic acid monomer. Pendent groups may be grafted to the backbone, such as by esterification and/or amidization/imidization of the units of the backbone that are derived from the carboxylic acid monomer.
- In general, the polymeric backbone can be an alternating structure whereby each carboxylic acid unit is spaced from the next carboxylic acid unit by at least one unit derived from a vinyl monomer, such as an alpha-olefin. The exemplary esterified copolymer can have at least 20 or at least 100 units derived from these monomers in its backbone. In one embodiment, the backbone chain of monomer units derived from the selected monomers is of no more than 10,000 such monomer units, or no more than 1000 such monomer units.

In one embodiment, the molar ratio is about 0.7:1 to 1:1.1 in the copolymer. It is to be appreciated, however, that the molar ratios used in the preparation of the copolymer may differ from those in the copolymer.
- The copolymer backbone optionally includes units derived from monomers other than the vinyl monomer (A1) and carboxylic acid monomer (A2) disclosed herein. For example, the backbone may include units derived from one or more monomers capable of polymerizing with one or both of the vinyl monomer and carboxylic acid monomer such as acrylates or methacrylates. The units derived from these other monomers constitute no more than 30 mole % or no more than 20 mole % or no more than 10 mole % of the monomer derived units in the copolymer. For example, 1-5% of the units in the backbone may be formed from these other monomers.

The Mw of the exemplary polymer, before esterification, can range from 3000 to 50,000, or 5000 to 30,000, or 5000 to 25,000, or 10,000 to 17,000. The Mw of the exemplary polymer, before esterification, can also range from about 5000 to 10,000, or 12,000 to 18,000, or 9000 to 15,000, or 15,000 to 20,000, or 8000 to 21,000, and in one embodiment, may be at least 10,000. The Mw of the exemplary esterified polymer, after esterification and optional reaction with the nitrogen-containing compound, can range from 5000 to 50,000, and in one embodiment, may be 5000 to 35,000.

- Exemplary aromatic amines include those amines wherein a carbon atom of the aromatic ring structure is attached directly to the amino nitrogen. The aromatic amines may be monoamines or polyamines. The aromatic ring may be a mononuclear aromatic ring (i.e., one derived from benzene) but can include fused aromatic rings, especially those derived from naphthalene.

U.S. Patent No. 5,744,429 discloses other aromatic amine compounds useful herein, particularly aminoalkylphenothiazines. N-aromatic substituted acid amide compounds, such as those disclosed inU.S. Pub. No. 20030030033 , may also be used herein. Suitable aromatic amines include those in which the amine nitrogen is a substituent on an aromatic carboxylic compound, that is, the nitrogen is not sp2 hybridized within an aromatic ring. - The aromatic amine may have an N-H group capable of condensing with the pendent carbonyl-containing group. Certain aromatic amines are commonly used as antioxidants. Examples of these are alkylated diphenylamines, such as nonyldiphenylamine and dinonyldiphenylamine. To the extent that these materials will condense with the carboxylic functionality of the polymer chain, they are also suitable for use herein. However, it is believed that the two aromatic groups attached to the amine nitrogen reduce its reactivity. Thus, suitable amines include those having a primary nitrogen atom (-NH2) or a secondary nitrogen atom in which one of the hydrocarbyl substituents is a relatively short chain alkyl group, e.g., methyl. Among such aromatic amines are 4-phenylazoaniline, 4-aminodiphenylamine (ADPA), 2-aminobenzimidazole, and N,N-dimethylphenylenediamine. Some of these and other aromatic amines may also impart antioxidant performance to the copolymers, in addition to dispersancy and other properties.
- In one embodiment, the amine component of the copolymer further includes an amine having at least two N-H groups capable of condensing with the carboxylic functionality of the copolymer. This material is referred to hereinafter as a "linking amine" as it can be employed to link together two of the copolymers containing the carboxylic acid functionality. It has been observed that higher molecular weight materials may provide improved performance, and this is one method to increase the material's molecular weight. The linking amine can be either an aliphatic amine or an aromatic amine; if it is an aromatic amine, it is considered to be in addition to and a distinct element from the aromatic amine described above, which typically will have only one condensable or reactive NH group, in order to avoid excessive crosslinking of the copolymer chains. Examples of such linking amines include aromatic amines having three or more aromatic rings, such as formaldehyde coupled ADPA or similar type aromatic amines disclosed in
WO2011146692 to the Lubrizol Corporation, published November 24, 2011, for example, at paragraphs [0068 to [0080]. Other examples of linking amines can include ethylenediamine, phenylenediamine, and 2,4-diaminotoluene; others include propylenediamine, hexamethylenediamine, and other, α-ω-polymethylenediamines. The amount of reactive functionality on such a linking amine can be reduced, if desired, by reaction with less than a stoichiometric amount of a blocking material such as a hydrocarbyl-substituted succinic anhydride. - In one embodiment, the amine includes nitrogen-containing compounds capable of reacting directly with a copolymer backbone. Examples of suitable amines include N-p-diphenylamine, 4-anilinophenyl methacrylamide, 4-anilinophenyl maleimide, 4-anilinophenyl itaconamide, acrylate and methacrylate esters of 4-hydroxydiphenylamine, and the reaction product of p-aminodiphenylamine or p-alkylaminodiphenylamine with glycidyl methacrylate.
- In one embodiment, the exemplary copolymer provides for oxidation control. Typically, the copolymer with oxidation control contains an incorporated residue of an amine-containing compound such as morpholines, pyrrolidinones, imidazolidinones, amino amides (such as acetamides), β-alanine alkyl esters, and mixtures thereof. Examples of suitable nitrogen-containing compounds include 3-morpholin-4-yl-propylamine, 3-morpholin-4-yl-ethylamine, β-alanine alkyl esters (typically alkyl esters have 1 to 30, or 6 to 20 carbon atoms), or mixtures thereof.

- The ester group and/or nitrogen containing group may be sufficient to provide 0.01 wt. % to 1.5 wt. % (or 0.02 wt. % to 0.75 wt. %, or 0.04 wt. % to 0.25 wt. %) nitrogen to the copolymer.
- The esterified copolymer (A) can be formed by a method which includes:
- (1) reacting (i) a vinyl monomer and (ii) a carboxylic acid monomer comprising an α,β-ethylenically unsaturated dicarboxylic acid or derivative thereof, to form a copolymer backbone, wherein the carboxylic acid monomer optionally has ester groups,
- (2) optionally, esterifying the copolymer backbone of step (1) to form an esterified copolymer, and
- (3) optionally, reacting the copolymer of step (1) or (2) with an nitrogen-containing compound in an amount to provide an esterified copolymer with at least 0.01 wt. % nitrogen; and whereby the resulting copolymer (A) is esterified in at least one of (1), (2), and (3).
- The copolymer backbone of the esterified copolymer (A) may optionally be prepared in the presence of a free radical initiator, solvent, or mixtures thereof. It will be appreciated that altering the amount of initiator can alter the number average molecular weight and other properties of the exemplary copolymer.
- The copolymer backbone may be prepared by reacting the carboxylic acid monomer with the vinyl monomer.
- The solvent can be a liquid organic diluent. Generally, the solvent has as a boiling point that is high enough to provide the required reaction temperature. Illustrative diluents include toluene, t-butyl benzene, benzene, xylene, chlorobenzene, various petroleum fractions boiling above 125°C, and mixtures thereof.
- The free radical initiator can include one or more peroxy compounds, such as peroxides, hydroperoxides, and azo compounds which decompose thermally to provide free radicals. Other suitable examples are described in J. Brandrup and E. H. Immergut, Editor, "Polymer Handbook", 2nd edition, John Wiley and Sons, New York (1975), pages II-1 to II-40. Examples of a free radical initiator include those derived from a free radical-generating reagent, and examples include benzoyl peroxide, t-butyl perbenzoate, t-butyl metachloroperbenzoate, t-butyl peroxide, sec-butylperoxydicarbonate, azobisisobutyronitrile, t-butyl peroxide, t-butyl hydroperoxide, t-amyl peroxide, cumyl peroxide, t-butyl peroctoate, t-butyl-m-chloroperbenzoate, azobisisovaleronitrile, and mixtures thereof. In one embodiment, the free radical generating reagent is t-butyl peroxide, t-butyl hydroperoxide, t-amyl peroxide, cumyl peroxide, t-butyl peroctoate, t-butyl-m-chloroperbenzoate, azobisisovaleronitrile or mixtures thereof. Commercially available free radical initiators include classes of compound sold under the trademark Trigonox®-21 from Akzo Nobel.
- An exemplary backbone polymer can be formed as follows: alpha-olefin is reacted with maleic anhydride in the presence of radical initiator and optionally in the presence of solvent. A solvent such as toluene can be used to lower backbone length by diluting the monomer concentration and through chain transfer to the benzylic protons.
Scheme 1 shows an example where the alpha-olefin is 1-dodecene, the initiator is tert-butyl peroxy-2-ethylhexanoate (sold under the tradename Trigonox 21S by Akzo Nobel), and the solvent is toluene. - Copolymerization of 1-dodecene and maleic anhydride in toluene under conventional free radical polymerization techniques leads to a low molecular weight copolymer.
- Esterification (or transesterification, when the copolymer backbone already contains ester groups and those of a different type are desired) of the exemplary copolymer backbone can be accomplished by heating any of the copolymers described above and one or more desired alcohols and/or alkoxylates under conditions typical for effecting esterification. Such conditions include, for example, a temperature of at least 80°C, such as up to 150°C or higher, provided that the temperature is maintained below the lowest decomposition temperature of any component of the reaction mixture or products thereof. Water or lower alcohol is normally removed as the esterification proceeds. These conditions may optionally include the use of a substantially inert, normally liquid, organic solvent or diluent, such as mineral oil, toluene, benzene, xylene, or the like, and an esterification catalyst, such as one or more of toluene sulfonic acid, sulfuric acid, aluminum chloride, boron trifluoride-triethylamine, methane sulfonic acid, trifluoromethanesulfonic acid, hydrochloric acid, ammonium sulfate, and phosphoric acid. Further details of conducting the esterification can be found in
U.S. Patent No. 6,544,935 , atcolumn 11. - In one embodiment, at least 2%, or at least 5%, or in
certain embodiments 10% to 20%, of the carboxy functions of the copolymer remain un-converted to ester groups. Most of these will subsequently be converted to nitrogen-containing groups. An excess of alcohols and/or alkoxylates over the stoichiometric requirement for complete esterification of the carboxy functions may be used in the esterification process provided the ester content of the polymer remains in an appropriate range, e.g., within the 90 to 99% range. The excess of alcohols and alkoxylates or unreacted alcohols and alkoxylates need not be removed as such alcohols and alkoxylates can serve, for example, as diluent or solvent in the exemplary lubricating composition. Similarly, optional reaction media, e.g., toluene, need not be removed as they can similarly serve as diluent or solvent in the lubricating composition. In other embodiments, unreacted alcohols, alkoxylates and diluents are removed by well-known techniques, such as distillation. - The nitrogen-containing compound may be directly reacted onto the copolymer backbone by grafting of the amine, or other nitrogen-containing functional group, onto the copolymer backbone either (i) in a solution using a solvent, or (ii) under reactive extrusion conditions in the presence or absence of solvent. The amine-functional monomer may be grafted onto the copolymer backbone in multiple ways. In another embodiment, the grafting is carried out in solution or solid form through a free radical initiator. Solution grafting is a well-known method for producing grafted copolymers. In such a process, reagents are introduced either neat or as solutions in appropriate solvents. The desired copolymer product may then be separated from the reaction solvents and/or impurities by appropriate purification steps.
- In one embodiment, the nitrogen-containing compound may be directly reacted onto the copolymer backbone by free radical catalyzed grafting of the copolymer in a solvent, such as an organic solvent such as benzene, t-butyl benzene, toluene, xylene, hexane, or a combination thereof. The reaction may be carried out at an elevated temperature in the range of 100°C to 250°C or 120°C to 230°C, or 160°C to 200°C, e.g., above 160°C, in a solvent, such as a mineral lubricating oil solution containing, e.g., 1 to 50, or 5 to 40 wt. %, based on the initial total oil solution of the copolymer and optionally under an inert environment.
- In one embodiment, the amine can have more than one nitrogen and can be selected from aliphatic amines and aromatic amines such that the R group attached to the amine that reacts with the carboxylic acid monomer derived groups contains at least one nitrogen atom, optionally substituted with hydrocarbyl groups.

These examples are non-exhaustive and are not intended to limit the scope of the invention.
- A 5L reaction flask was charged with 490.3 g of maleic anhydride (MAA), 841.6 g of 1-dodecene and 860.2 g of toluene. A molar ratio of the 1-dodecene:maleic anhydride was 1:1. The flask was fitted with a PTFE gasket and a 5-port flange lid equipped with an overhead stirrer, stirrer guide, thermocouple, nitrogen inlet (250 cm3/min nitrogen), silicon septa with peristaltic pump attached via cannula and a water condenser. The reaction flask and its contents were heated to 105 °C.
- A mixture of 6.55 grams of Trigonox®C (a commercially available tert-butyl peroxybenzoate initiator from Akzo Nobel), and 124.5 g of toluene were mixed together and added to the reaction flask over 480 min. via the peristaltic pump. The reaction mixture was stirred at 105 °C for several hours.
- An additional mixture of 19.65 grams of Trigonox®C (a commercially available tert-butyl peroxybenzoate initiator from Akzo Nobel), and 373.35 g of toluene were mixed together and added to the reaction flask over 480 min. via the peristaltic pump. The reaction mixture was stirred at 105°C for several hours.
- The reaction flask was fitted with a Dean-Stark trap and the reaction mixture heated to 110 °C with stirring. 725 g of Alfol 810™ was added over 80 min and the resulting reaction mixture stirred for 1 hr. An additional 725 g of Alfol 810™ and 34.3 g of a 70% aqueous solution of methane sulfonic acid were added to the reaction flask over 80 min while gradually increasing the reaction temperature to 145°C. After several hours 72g of n-butanol and 17.2 g of 70% aqueous solution of methane sulfonic acid were added and stirred for 3 hr. An additional 72g of n-butanol was added and the reaction stirred for 2 hours. An additional 72g of n-butanol was added and the reaction stirred for several hours. An additional 72g of n-butanol was added and the reaction stirred for 3 to 4 hours. An additional 72g of n-butanol was added and the reaction stirred for 2 to 3 hours. Sufficient sodium hydroxide (50% aqueous sodium hydroxide solution) was added to quench the methane sulfonic acid and the mixture was stirred for 1 hour followed by the addition of 10.15 g of 3-(dimethylamino)-1-propylamine and stirred for an additional 2 hours. 309.1 g of Nexbase 3050 was added and stirred. The reaction flask was fitted for vacuum stripping and the resultant product vacuum-stripped (-26 in Hg) at 150°C and held for 3 hours. The vacuum was removed and the flask was cooled to 120°C.
- The resulting reaction mixture was filtered twice using fax-5 and filter cloth. GPC run in tetrahydrofuran against polystyrene standards showed a Mw of 24,100, Mn of 16,000.
- Table 1 shows gear oil fluids prepared to meet SAE 75W-90 or 80W-90 grades targeting a kinematic viscosity of 17.5 cSt fluid at 100°C. Brightstock would not be capable of thickening
PAO 4 sufficiently to make the particular viscosity and is formulated as a typical 80W-90 fluid with a pour point depressant (PPD) to enable improved cold flow properties.TABLE 2 Fluid 1Fluid 2Fluid 3Fluid 4Fluid 5VIS Grade SAE 75W-90 SAE 80W-90 SAE 75W-90 SAE 75W-90 SAE 75W-90 Base oil 143.72 62.06 45.23 68.14 Base oil 247 Additive Package 10 10 10 10 10 PPD 2 VM1 46.28 VM2 41 VM3 27.94 VM4 44.77 VM5 21.86 VM1=esterified copolymer prepared similar to Example 1 but having a lower molecular weight (Mw) of about 15,000-16,000

VM5=ethylene propylene copolymer - The fluids are compared in a number of key viscosity evaluations.
Fluid 1 has the most favorable VI and HTHS. The viscosity reduction as temperature increases can be linked to VI but as shear rate increases the impact of the non-Newtonian behavior can manifest in differing levels of shear thinning at high shear rate. Comparison offluid 3 andfluid 5 shows equivalent HTHS, equivalent KV100, but a substantial difference in VI OnlyFluid 1 is according to the invention.TABLE 3 Fluid 1Fluid 2Fluid 3Fluid 4Fluid 5VIS Grade SAE 75W-90 SAE 80W-90 SAE 75W-90 SAE 75W-90 SAE 75W-90 KV40 102.6 186.3 127.2 112.8 108.0 KV100 17.55 17.57 17.63 16.92 17.52 Viscosity Index (VI) 189 102 153 164 179 HTHS 6.02 5.05 5.56 5.36 5.54 - High shear rheology is also conducted on these fluids. The PSC Instruments USV (Ultra-Shear Viscometer) is used to determine the viscosity of the fluids at shear rates higher than the typical 1x106s-1 as run in the HTHS using a tapered bearing or plug simulator (TBS or TPS). Similar to the traditional HTHS-capable instruments, USV uses a classic rotor-stator design to apply a very quick pulse to the rotor providing shear rates up to 10,000,000 s-1. Due to the susceptibility of some polymer-containing solutions to be affected by permanent shear loss during testing, fresh sample is run at each individual shear rate.
- The procedure for testing the samples is as follows: temperature and shear rate parameters are assigned in the computer. The application allows for multiple temperatures and shear rates to be assigned, but as stated individual temperatures and shear rates are used. Once the temperature and shear rate profile has been loaded, the new sample is loaded. Numerous flushing steps of the current test fluid are required before the sample (0.5 mL) is loaded into the test chamber. Once loaded and set to run, the motor and flywheel are set to spin to provide the appropriate shear rate. A clutch engages the rotor and three pulses, approximately five second apart, are applied to the sample. The viscosity is determined by calculating the average of the resistance on the rotor.
-
Figures 1 to 4 summarize the responses of the fluids to high shear from 50 to 150°C. At lower operational temperatures under low load the higher viscosity or thicker films can be detrimental to operational efficiency.Fluid 1 has lower viscosity at 50°C under high shear conditions than the comparative fluids which have an impact on the operational efficiency under low load and high shear rates. - At high temperatures fluid film support can be compromised and can negatively impact durability. For non-Newtonian fluids the rate of drop in viscosity will depend on the polymer type and
Figure 2 shows that as temperature increased to 100°C (fluids normalized to KV at 100°C) fluid 5 shows the most substantial reduction in viscosity,fluid 2 shows the least reduction indicating the least and most Newtonian in nature respectively. -
Figures 3 and 4 show the fluid response to high shear at 125°C and 150°C. At these temperatures viscosity is substantially lower than at 100°C. Thus, fluid film protection under these conditions can be compromised.Fluid 1 shows the lowest drop in viscosity at high temperature (>100°C) and high shear rate. - Unless otherwise indicated, each chemical or composition referred to herein should be interpreted as being a commercial grade material which may contain the isomers, by-products, derivatives, and other such materials which are normally understood to be present in the commercial grade. However, the amount of each chemical component is presented exclusive of any solvent or diluent oil, which may be customarily present in the commercial material, unless otherwise indicated. As used herein, the expression "consisting essentially of" permits the inclusion of substances that do not materially affect the basic and novel characteristics of the composition under consideration. As used herein any member of a genus (or list) may be excluded from the claims.
- As used herein, the term "(meth) acrylic" and related terms includes both acrylic and methacrylic groups.
- As used herein, the term "a primary alcohol branched at the β- or higher position" relates to an alcohol with branching at the 2- position or a higher position (e.g., 3-, or 4-, or 5-, or 6-, or 7- position, etc.).
- As used herein, the term "hydrocarbyl substituent" or "hydrocarbyl group" is used in its ordinary sense, which is well-known to those skilled in the art. Specifically, it refers to a group having a carbon atom directly attached to the remainder of the molecule and having predominantly hydrocarbon character. Examples of hydrocarbyl groups include:
- a. hydrocarbon substituents, that is, aliphatic (e.g., alkyl or alkenyl), alicyclic (e.g., cycloalkyl, cycloalkenyl) substituents, and aromatic-, aliphatic-, and alicyclic-substituted aromatic substituents, as well as cyclic substituents wherein the ring is completed through another portion of the molecule (e.g., two substituents together form a ring);
- b. substituted hydrocarbon substituents, that is, substituents containing non-hydrocarbon groups which, in the context of this invention, do not alter the predominantly hydrocarbon nature of the substituent (e.g., halo (especially chloro and fluoro), hydroxy, alkoxy, mercapto, alkylmercapto, nitro, nitroso, and sulfoxy);
- c. hetero substituents, that is, substituents which, while having a predominantly hydrocarbon character, in the context of this invention, contain other than carbon in a ring or chain otherwise composed of carbon atoms; and
- d. heteroatoms include sulfur, oxygen, nitrogen, and encompass substituents as pyridyl, furyl, thienyl and imidazolyl. In general, no more than two, in one aspect no more than one, non-hydrocarbon substituent will be present for every ten carbon atoms in the hydrocarbyl group; typically, there will be no non-hydrocarbon substituents in the hydrocarbyl group.
