Abstract
Description
[0001] Priority Claim This application is based on and asserts priority to U.S. non-provisional application No. 18 / 931,902, filed on October 30, 2024, as a partial continuation, which is based on parent application No. 18 / 904,859 with the same title, filed on October 2, 2024, the disclosure of which is incorporated herein by reference. Invention Field
[0002] This invention relates to novel compounds, their preparation, and uses. In particular, the novel compounds are novel polyisobutylene compounds, more particularly, polyisobutylene polyether alcohol amines, and more specifically, mono-polyisobutylene polyether alcohol amines, bis-polyisobutylene polyether alcohol amines, tris-polyisobutylene polyether alcohol amines, and tetrakis-polyisobutylene polyether alcohol amines, and mixtures thereof. This invention also relates to novel processes for generating these mono-, bis-, tris-, and tetra-polyisobutylene polyether alcohol amine compositions, and their uses in lubricants, surfactants, emulsifiers, resins, adhesives, and many similar applications. Background of the Invention
[0003] Polyisobutylene (PIB) is well known in the field and is typically produced by polymerizing isobutylene in the presence of a catalyst. PIB consists of long-chain molecules of isobutylene of various lengths and has different number-average molecular weights (Mn) and polydispersity indices (PDI), thus giving it selective properties such as viscosity.
[0004] Traditional PIB compounds and compositions, primarily characterized by internal unsaturation (double bonds), tend to have low reactivity and are mainly derived from isobutylene and typical aluminum-based catalysts. More reactive PIB compounds and compositions, however, exhibit a higher percentage of unsaturation at the ends of the PIB molecule and are primarily generated from more selective fluorinated catalysts such as BF3.
[0005] As is well known, variations in PIB compounds and compositions, and differences in unsaturation (more specifically, α-vinylene content), depend on process conditions such as isobutylene concentration, temperature, catalyst, and solvents used.
[0006] In most cases, the reactivity of PIB determines its application and ultimately the performance of the final product. Traditional PIB is used in applications such as sealants, caulking agents, adhesives, packaging materials, and greases. More reactive PIB is primarily used in lubricants and fuel additives; however, traditional PIB can also be used. Other applications include sizing, ethylene oxide derivatives, and uses in rubber compositions.
[0007] PIB, preferably more reactive, is primarily used to generate well-known lubricants such as polyisobutylene succinimide or polyisobutylene succinamide (PIBSI). PIBSI is formed by reacting polyisobutylene succinic anhydride (PIBSA) or polyisobutylene succinic acid (an intermediate of PIBSI) with a monoamine or polyamine (especially a primary amine). PIB, being mostly nonpolar, requires reaction with, for example, maleic anhydride to form a polar group, enabling the linking group (i.e., succinic anhydride) to react and form PIBSA. This technique is well known in the art and described in numerous patents and publications, including U.S. Patent Nos. 7,339,007 and 9,315,761, which are incorporated herein by reference in their entirety.
[0008] Most commercial PIBSIs are produced using a thermal process that begins with PIBs having a relatively high proportion of terminal vinyl bonds (referred to in the industry as "reactive" or "highly reactive" PIBs). Highly or moderately reactive PIBs are well known in the art and are further described in U.S. Patent Nos. 6,562,913 and 9,309,339, which are incorporated herein by reference in their entirety. Conventional PIBs typically have a relatively low amount of terminal vinyl bonds, see, for example, U.S. Patent No. 3,272,746.
[0009] The aforementioned thermal and halogen-assisted reactions often produce significant amounts of haze and highly colored deposits, which must be filtered off before use in the final product (PIBSI). Tar is often generated during thermal processes, which coats the reactor walls, necessitating frequent, time-consuming, and therefore costly cleaning of the reaction vessel. The formation of deposits and tar is believed to be at least partly due to the decomposition and / or polymerization of unsaturated enophiles (typically maleic anhydride). Efforts have been made to eliminate the resulting haze and deposits, as documented in U.S. Patent Nos. 7,339,007, 4,958,034, 5,021,169, and 5,241,003.
[0010] U.S. Patent No. 3,794,586 relates to a lubricating oil composition comprising a reaction of a polyolefin epoxide and an amine compound (including polyisobutylene epoxide) to form a reaction product of a mono-polyisobutylene hydroxyalkyl-substituted polyether amine. U.S. Patent Nos. 6,497,736 and 6,346,129 disclose fuel compositions containing mono-polyisobutylene hydroxyalkyl-substituted amines for use as automotive fuel cleaners. Furthermore, Canadian Patent Application CA 2,856,684A1 describes an amine mixture of mono-polyisobutylene amine and aliphatic amines for use in cleaning engine intake valves and nozzles.
[0011] Based on both ether and amine groups, polyetheramines are well-known aliphatic organic species in the industry. Polyetheramines are typically produced by reacting ethylene oxide or propylene oxide with a polyol followed by amination. Commercially available polyetheramines are available in various molecular weights, including monofunctional, difunctional, and trifunctional forms. The main uses of polyetheramines are as epoxy resin curing agents and as fuel additives or cleaners to prevent sludge and other deposits in gasoline engines. For example, see U.S. Patent Nos. 4,975,096, 5,489,630, 7,550,550, and 9,315,761; U.S. Patent Publications 2013 / 00234451A1 and 2018 / 0023020A1; and European Patent EP128715B1.
[0012] U.S. Patent Nos. 7,820,604, 7,928,044, and 7,816,309 and European Patent EP2,797,970B1 discuss the reaction of copolymers and terpolymers of polyisobutylene and maleic anhydride, as well as polyisobutylene / maleic anhydride / hexadecene compositions, with polyetheramines to produce oil additives. U.S. Patent No. 9,315,761 addresses the use of metallocene-made vinyl-terminated polypropylene copolymers and vinyl-terminated atactic polypropylene epoxides and the reaction of these polymers with polyetheramines. U.S. Patent Publication No. US2018 / 002320A1 discloses the typical reaction of PIBSI with polyetheramines to produce polyisobutylene polyetherimides. These compounds have properties very similar to PIBSI, maintaining unsaturation in the final product and are not alcoholic amines.
[0013] The US Patent Publication No. US2014 / 0087983A1, published on March 27, 2014, is for lubricants and fuel dispersants containing amination products of epoxide-terminated macromonomers and amine compounds such as polyalkylene polyamines and ethylenediamines, but does not refer to polyetheramines.
[0014] US Patent Publication No. US2006 / 0063844A1, published on March 23, 2006, discloses a method for generating amine-functionalized polyisobutylene primarily for microemulsion coating applications from a mixture of mono- and bis-polyisobutylene, which is mainly functionalized with monoamine, and mono- and bis-polyisobutylamine.
[0015] While the generation of specific polyisobutylene alcohol amines from polyisobutylene epoxides is known, there is a need to modify the chemical properties of head groups derived from fuel and engine oil lubricant additives, adhesives and sealants, epoxy and polyurea coatings, composites, emulsion stabilizers, paraffin inhibitors, and the like, affecting the solubility, reactivity, and performance standards of the final compounds in a variety of applications. Furthermore, there is a persistent need in the field for highly efficient one-pot synthesis of these compounds with minimal byproducts, thereby improving compounds or compositions that offer enhanced multifunctional chemical and physical properties.

[0027] In one embodiment, the hydrophilic polyetheramine can be a mono-, di-, tri-, tetra-, or polyfunctional polyetheramine. Methods for preparing hydrophilic polyetheramines are well known and can be found, for example, in U.S. Patent Nos. 3,654,370, 3,832,402, 4,990,476, and 2017 / 0362164A1, the contents of which are incorporated herein by reference. Generally, these hydrophilic polyetheramines can be produced by alkylating a mono-, di-, tri-, tetra-, or polyfunctional alcohol or alkylphenol with an alkylene oxide (such as ethylene oxide, propylene oxide, butane oxide, or mixtures thereof) to form an alkylene oxide adduct, followed by catalytic amination of the alkylene oxide adduct in the presence of hydrogen and ammonia to form a polyetheramine. In some embodiments, the hydrophilic polyetheramine can be initiated by an amine, which is alkylated and then amination.
[0028] According to one embodiment, the polyetheramine, preferably a hydrophilic polyetheramine, is a polyether monoamine having formula (13) or formula (14): Equation (13) Where R is hydrogen or methyl, and a and b are independent integers from about 1 to about 150; or Equation (14) Where Y is hydrogen or methyl, Z is an alkyl group from 1 to 40 carbon atoms, or an alkylphenol group from 1 to 40 carbon atoms, and w is an integer from about 1 to about 100.

[0035] Generally, the process for generating the polyisobutylene polyether amine compound of the present invention involves contacting a polyisobutylene epoxide, a hydrophilic polyether amine, a diluent, an optional geological solvent, and an optional catalyst in a reaction vessel at pressures, temperatures, and reaction times sufficient to form the compound of the present invention.
[0036] In one embodiment, the polyisobutylene polyether amine compound of the present invention is produced via a process comprising the following steps: (i) mixing polyisobutylene epoxide with a hydrophilic polyether amine in a reaction vessel at a molar ratio of about 1:1 or less (amine: epoxide); (ii) optionally introducing a diluent into the reaction vessel with or without a catalyst; (iii) optionally adding a protic solvent to the reaction vessel; (iv) heating the reaction vessel under pressure for a period of time; (v) optionally removing the diluent; and (vi) recovering the polyisobutylene polyether amine compound.
[0037] In another embodiment, the process of the present invention is directed to a process for generating a polyisobutylene polyether amine compound, the process comprising the steps of: (i) mixing a polyisobutylene epoxide with a hydrophilic polyether amine in a reaction vessel at a molar ratio of about 1:1 or less (amine: epoxide); (ii) optionally introducing a diluent into the reaction vessel with or without a catalyst; (iii) optionally adding a protic solvent; (iv) heating the reaction vessel under pressure for a period of time; (v) optionally removing the diluent; and (vi) recovering the polyisobutylene polyether amine compound.
[0038] In a preferred embodiment, the present invention relates to a process for generating a PIB-PEAA composition, the process comprising the steps of: (i) contacting a polyisobutylene epoxide with a hydrophilic polyether amine in a reactor at a molar ratio of hydrophilic polyether amine to polyisobutylene epoxide of less than 0.9:1 (amine: epoxide); (ii) optionally introducing a proton solvent; (iii) optionally adding a catalyst to the reactor; and (iv) adding a diluent to the reactor; and (iv) removing the diluent to form a PIB-PEAA composition comprising more than 50 molar percentages (50 mol%) of PIB-PEAA.
[0039] A surprising finding, among other discoveries, is that controlling the molar ratio of polyetheramine (PEA) to polyisobutylene produces very pure compounds with reduced or almost eliminated percentages of minor components.
[0040] In a general embodiment, in the process for generating the PIB-PEAA compound and composition of the present invention, the molar ratio of polyetheramine to isobutylene epoxide is less than 1:1, preferably less than 0.9:1, more preferably 0.8:1, and even more preferably 0.7:1, and even more preferably less than 0.6:1, or 0.5:1 or less. In another preferred embodiment, the molar ratio of polyetheramine to isobutylene epoxide is in the range from less than 1:1 to 0.2:1, more preferably 0.9:1 to 0.2:1, even more preferably from 0.8:1 to 0.2:1, even more preferably from 0.7:1 to 0.2:1, even more preferably from 0.6:1 to 0.3:1, and most preferably from 0.5:1 to 0.2:1.
[0041] Polyetheramines are produced with a target amine content. That is, a polyether may contain one molar equivalent of a primary amine (monoamine) and / or two molar equivalents of a primary amine (diamine) and / or three molar equivalents of a primary amine (triamine) and / or four molar equivalents of a primary amine (tetraamine) and / or possibly more (polyamine). The choice of the amine content of any particular polyetheramine is determined by the specific end-use application or the desired end-use properties.
[0042] In one embodiment, mono-PIB-PEAA is produced using a molar ratio of polyetheramine (one or more mono-, di-, tri-, and tetra-amines) to polyisobutylene epoxide of less than 1.2:1, preferably less than 1.1:1, more preferably less than 1.05:1, and most preferably about 1:1.
[0043] In another embodiment, bis-PIB-PEAA is produced using a molar ratio of polyetheramine (one or more di-, tri-, and tetraamines) to polyisobutylene epoxide of less than 0.7:1, preferably less than 0.6:1, more preferably less than 0.55:1, and most preferably about 0.5:1.
[0044] In another embodiment, PIB-PEAA is produced using a molar ratio of less than 0.5:1 of polyetheramine (one or more tri- and tetramines) to polyisobutylene epoxide, preferably less than 0.45:1, more preferably less than 0.4:1, and most preferably about 0.3:1.
[0045] In another embodiment, 4-PIB-PEAA is produced using a molar ratio of polyetheramine (tetraamine or higher) to polyisobutylene epoxide of less than 0.4:1, preferably less than 0.35:1, more preferably less than 0.3:1, and most preferably about 0.25:1.
[0046] In another embodiment, the molar ratio of polyetheramine to polyisobutylene epoxide is such that the polyisobutylene epoxide used is in slight to slight excess. In another embodiment, the molar ratio of polyetheramine to polyisobutylene epoxide is such that the polyetheramine used is in slight to slight excess. A preferred molar ratio of polyetheramine to polyisobutylene epoxide is such that one, two, three, or four moles of polyisobutylene epoxide are used per mole of polyetheramine to produce mono-, bis-, para-, or tetra-PIE-PEAA, depending on the amount of primary amine contained in the PEA.
[0047] In another embodiment of the above process, when the hydrophilic polyetheramine and polyisobutylene epoxide are as described above, the particular PIB-PEAA composition contains more than 70 mol%, preferably more than 80 mol%, more preferably more than 90 mol%, and most preferably more than 95 mol% of PIB-PEAA.
[0048] Polyisobutylene polyether alcohol amine compounds are used in many applications, including friction modification, dispersant, fuel additive, emulsion stabilizer, surfactant, adhesive, battery, etc.

[0054] Detailed description of the invention
[0055] This document discloses novel polyisobutylene polyether alcoholamines (PIB-PEAA), namely mono-polyisobutylene polyether alcoholamines (mPIB-PEAA), di-polyisobutylene polyether alcoholamines (bPIB-PEAA), tri-polyisobutylene polyether alcoholamines (tPIB-PEAA), and tetra-polyisobutylene polyether alcoholamines (tkPIB-PEAA), as well as processes for generating PIB-PEAA from polyisobutylene epoxides (PIBEP) and mono- or polyfunctional polyether alcoholamines, and numerous uses of PIB-PEAA. For the purposes of this patent specification and the appended claims, the term polyisobutylene polyether alcoholamine (PIB-PEAA) refers independently to each of the mPIB-PEAA, bPIB-PEAA, tPIB-PEAA, and tkPIB-PEAA compounds.
[0056] Polyisobutylene and the formation of polyisobutylene epoxide The polyisobutylene epoxide produced by the PIB-PEAA reaction currently used is obtained by oxidizing the polyolefin with an oxidizing agent to provide an epoxide or epoxide, wherein the ethylene oxide ring is oxidized from the double bond in the polyolefin. Polyisobutylene is a preferred polyolefin.
[0057] Polyisobutylene (PIB) is a long-chain molecule synthesized by polymerizing or linking isobutylene molecules. Many well-known processes for producing PIB exist in the field, including, but not limited to, U.S. Patent Nos. 9,598,655, 9,617,363, 9,309,339, 6,562,913, 8,524,843, 8,946,361, 11,326,004, 9,074,026, and 9,809,665, and EP1381637B2, which are incorporated herein by reference in their entirety.
[0058] Polyisobutylene (PIB) exists in many forms with a wide range of molecular weights, from several hundred to several million. Generally, the preferred number-average molecular weight (Mn) is in the range of 100 to 5000, more preferably 400 to 4000, and most preferably about 500 to about 3500 or less. Furthermore, due to varying chain lengths, PIB also exhibits a wide range of polydispersity indices (PDI) measured using GPC with polyisobutylene standards, typically in the range of about 1.3 to less than 5, more preferably from about 1.4 to less than 4, and most preferably from about 1.5 to less than 3. Mn, along with PDI, are key properties used to determine the useful viscosity and flash point of PIB for a particular application.
[0059] PIBs are available from many commercial manufacturers, such as the TPC Group, INEOS Oligomers, Infineum, Lubrizol, and BASF. Each company offers a variety of combinations of low, medium, and high reactive PIBs, such as GLISSOPAL® and OPPANOL® from BASF in Ludwigshafen, Germany; Indopol® from INEOS Oligomers in London, UK; and LUBRIZOL 3108 from Lubrizol in Wycliffe, Ohio.
[0060] A variety of PIB types are available from TPC Group in Houston, Texas, including highly reactive PIBs (HR-PIBs) such as HR545, HR595 and HR5230; moderately reactive PIBs (LM-PIBs) such as TPC 175 and TPC 1160; and di-isobutylene (DIB) and triisobutylene (TIB).
[0061] The decisive factor for distinguishing between medium and high reactive PIBs is the degree of polymerization based on the concentration of various double bond end group types (i.e., α, β, tetrasubstituted, trisubstituted, and substituted α, etc.). Differences between PIBs can be determined by measuring the α-vinylene content. Conventional or low to medium reactive PIBs have an α-vinylene isobutylene isomer content between 0 and 10%, while high reactive PIBs have an α-vinylene isobutylene isomer content between 60% and 90% or higher.
[0062] Surprisingly, it was further discovered that the PIB-PEAA of the present invention can be generated using conventional or highly reactive PIB as the starting monomer for the formation of polyisobutylene epoxide. In one embodiment, highly reactive PIB is preferred in the process for generating the polyisobutylene epoxide starting monomer to be reacted with polyetheramine in the process of the present invention.
[0063] Epoxidation of olefins and other polymers Epoxidation of a wide variety of olefins, including polymers with double bonds, is well known in the field. Representative prior art showing various procedures for epoxidizing some types of unsaturated materials has been found in: Song et al., *Journal of Polymer Science and Polymer Chemistry*, Vol. 40, pp. 1484-1497 (2002); Shigenobu et al., *Maruzen Petrochemical*; Japanese Patent Application No. JP2001 031716A, published February 26, 2001; Suzuki et al., *Journal of Applied Polymer Science*, Vol. 72, pp. 103-108 (1999); and Li et al., *Macromolecules*, Vol. 38, pp. 6767-6769 (2005). Epoxidation of nonpolymeric materials using catalysts or selected reaction media solvents is also well known in the field. Representative prior art references showing these types of epoxides include: Hellmann et al., Angewandte Chemie International Edition, Vol. 30, No. 12, pp. 1638-1641 (1991); Van Vliet et al., Chem. Commun., pp. 821-822 (1999); and Neimann et al., Organic Letters, Vol. 2, No. 18, pp. 2861-2863 (2000). Examples of different types of intermediate polyisobutylene epoxides produced according to the present invention are illustrated in the following description via the reactions described below, which are always referred to as type I, type II, or type III polybutenes represented by formulas 10, 11, and 12 respectively: , Type 1 Equation (10) , Type 2 Equation (11) , Type 3 Equation (12) Where x is from 1 to about 200, preferably from 1 to about 150, more preferably from 1 to about 100, and most preferably between 1 and 50, and the content of polyisobutylene epoxide species containing type I, type II, and / or type III polyisobutylene epoxides is at least 50 mol%, preferably 60 mol%, and most preferably 80 mol% or higher. In one embodiment of the above general formula, x is 100, and in another embodiment, x is 50. In yet another embodiment of the above general formula, x is an integer in the range of 90 to 110, and in another embodiment, x is an integer in the range of 40 to 60.
[0064] It is generally believed that type 3 epoxides are more reactive to amination than type 1 and type 2 epoxides, and these polyisobutylene epoxides are preferred. However, it has been surprisingly found that type 1 and type 2 epoxides also exhibit reactivity to amination. Therefore, polyisobutylene epoxides containing higher amounts of type 1 and type 2 epoxy groups are also used in this invention. In any case, if a type 3 epoxide is desired, it is produced starting from polyisobutylene containing a high concentration of type 3 double bonds (as shown above).
[0065] In a preferred embodiment, the molar percentage of type 1, type 2, and / or type 3 polyisobutylene epoxides used in the process of the present invention is at least 30 mol%, preferably at least 40 mol%, more preferably at least 50 mol%, even more preferably at least 60 mol%, and most preferably greater than 70 mol% to about 80 mol%, preferably from about 80 mol% to 85 mol% to about 90 mol% to 95 mol%, and most preferably greater than about 95 mol%. In another embodiment, the molar percentage of type 3 polyisobutylene epoxides used is at least 50 mol% to about 60 mol%, preferably from about 65 mol% to about 70 mol%, and most preferably greater than about 70 mol%. In yet another embodiment, the molar percentage of type 3 polyisobutylene epoxides used is at least 70 mol% to about 80 mol%, preferably from about 80 mol% to 85 mol% to about 90 mol% to 95 mol%. In another embodiment, the molar percentage of type 1 and type 3 polyisobutylene epoxides used is at least 85 mol% or up to 98 mol%, and preferably greater than about 90 mol% to 95 mol%.
[0066] In one embodiment, a combination of type I, type II, and type III polyisobutylene epoxides is used in the process of the present invention to generate polyisobutylene polyether alcoholamine. In a preferred embodiment, more than 70 mol%, preferably more than 80 mol%, or even 90 mol%, of type III polyisobutylene epoxide is used.
[0067] In yet another embodiment, the polyisobutylene epoxide (PIBEP) has a number average molecular weight (Mn) in the range of 400 to 5000 and an ethylene oxide oxygen value of 2% to 0.15%, more preferably in the range of 400 to 3500 and an ethylene oxide oxygen value of 2% to 0.22%, and even more preferably in the range of 400 to 3000 and an ethylene oxide oxygen value of 2% to 0.25%.
[0068] Commercially available examples of polyisobutylene containing high concentrations of type III double bonds are TPC 5230, TPC 545, and TPC 595, produced and obtained by TPC Corporation in Houston, Texas. Non-limiting examples of polyisobutylene containing low amounts of type III double bonds but with increased amounts of type I and type II double bonds are Indopol® H-100, H-300, H-1200, H-1500, H-1900, H-2100, H-6000, and H-18000, produced by INEOS Oligomers in London, UK.
[0069] The presence of type 4 tetra-polyisobutylene epoxide is due to the processes used to produce polyisobutylene epoxides, and it exists in various amounts alongside all other types 1, 2, and 3. For example, type 4 exists in highly reactive polyisobutylene epoxides (type 3) in amounts from about 1 to less than 5 mol%, more likely from 1 mol% to less than 3 mol%, and in low to medium reactive polyisobutylene epoxides (types 1 and 2), type 4 is believed to exist in amounts from 25 mol% to 40 mol% or higher, more likely from about 30 mol% to about 40 mol%.
[0070] hydrophilic polyetheramine Generally, these hydrophilic polyetheramines can be produced by alkylation of mono-, di-, tri-, tetra-, or polyfunctional alcohols or alkylphenols with alkyl oxides (such as ethylene oxide, propylene oxide, butane oxide, or mixtures thereof) to form alkyl oxide adducts, followed by catalytic amination of the alkyl oxide adducts in the presence of hydrogen and ammonia to form polyetheramines.
[0071] The polyetheramines used for reacting with polyisobutylene epoxides are preferably hydrophilic polyetheramines, which are mono-, di-, tri-, tetra-, or polyfunctional polyetheramines. Methods for preparing hydrophilic polyetheramines are well known and can be found, for example, in U.S. Patent Nos. 3,654,370, 3,832,402, and 4,990,476, the contents of which are incorporated herein by reference.
[0072] Hydrophilic polyetheramines are mono-, di-, tri-, tetra-, or polyfunctional polyetheramines based on PPG (polypropylene glycol) and PEG (polyethylene glycol) polyether backbones, as well as polytetramethylene glycol (PTMEG)-based polyetheramines or mixtures thereof.
[0073] There are many commercially available hydrophilic polyetheramines that can be reacted with polyisobutylene epoxides to produce the polyisobutylene polyether alcoholamine compounds of this invention. Huntsman Corporation of Woodland, Texas manufactures polyetheramines under the trade name JEFFAMINE® with various molecular weights (MW) and average amine hydrogen equivalents (AHEW) measured in grams per equivalent. While not wishing to be bound by any particular theory, it is believed that selecting an appropriate polyetheramine for a better use or application when producing the polyisobutylene polyether alcoholamine compounds of this invention will improve the desired use or application. For example, it is believed that the use of the polyisobutylene polyether alcoholamine compounds of this invention in epoxy resins may produce epoxy resins with improved water resistance, adhesion, flexibility, and other improved properties.
[0074] Monoamine One type of polyetheramine is called a monoamine, which, for the purposes of this article, is based on a PPG or PEG / PPG backbone. Huntsman manufactures a series of propylene glycol-based monoamines under the trademark JEFFAMINE®, including, for example, JEFFAMINE® M-600 with a molecular weight (Mw) of 600 and an AHEW of 291 g / equivalent, and M-2005 with a MW of 2000 and an AHEW of 1045 g / equivalent, both of which are claimed to be suitable for use with polymers that can be blended with other polymers.

[0098] In one embodiment, the molar ratio of polyetheramine to polyisobutylene epoxide is less than 1:1, preferably less than 0.9:1, more preferably 0.8:1, and even more preferably 0.7:1, and even more preferably less than 0.6:1, or 0.5:1 or less. In another preferred embodiment, the molar ratio between polyetheramine and isobutylene epoxide is in the range of less than 1:1 to 0.2:1, preferably from 0.9:1 to 0.2:1, even more preferably from 0.8:1 to 0.2:1, even more preferably from 0.7:1 to 0.2:1, and even more preferably from 0.6:1 to 0.3:1, and most preferably from 0.5:1 to 0.2:1.
[0099] In another embodiment, the molar ratio of polyetheramine to polyisobutylene epoxide is such that the polyisobutylene epoxide used is in slight to slight excess. In another embodiment, a preferred molar ratio of polyetheramine to polyisobutylene epoxide is such that at least two moles of polyisobutylene epoxide are used for every mole of polyetheramine used.
[0100] The process of production Generally, the process for generating the polyisobutylene polyether amine compound of the present invention is by contacting polyisobutylene epoxide, hydrophilic polyether amine, diluent, proton solvent mixture, and optionally catalyst in a reaction vessel at pressure and temperature sufficient to form the compound of the present invention.
[0101] In one embodiment, the polyisobutylene polyether amine compound of the present invention is produced via a process comprising the following steps: (i) mixing polyisobutylene epoxide with a hydrophilic polyether amine in a reaction vessel at a molar ratio of about 1:1 or less; (ii) optionally introducing a diluent into the reaction vessel with or without a catalyst; (iii) optionally adding a protic solvent to the reaction vessel; (iv) heating the reaction vessel under pressure for a period of time; (v) optionally removing the diluent; and (vi) recovering the polyisobutylene polyether amine compound.
[0102] In another embodiment, the process of the present invention is directed to a process for generating a polyisobutylene polyether amine compound, the process comprising the steps of: (i) mixing a polyisobutylene epoxide with a hydrophilic polyether amine in a reaction vessel at a molar ratio of about 1:1 or less; (ii) optionally introducing a diluent into the reaction vessel with or without a catalyst; (iii) optionally adding a protic solvent; (iv) heating the reaction vessel under pressure for a period of time; (v) optionally removing the diluent; and (vi) recovering the polyisobutylene polyether amine compound.
[0103] In another embodiment, the process of the present invention is aimed at generating a polyisobutylene polyetheramine compound by reacting a hydrophilic polyetheramine with a polyisobutylene epoxide, preferably in a molar ratio of about 1:1 to the hydrophilic polyetheramine and the polyisobutylene epoxide. In yet another embodiment, the hydrophilic polyetheramine is a product produced by alkylating a mono-, di-, tri-, tetra-, or polyfunctional alcohol or alkylphenol with an alkylene oxide to form an alkylene oxide adduct, followed by catalytic amination of the alkylene oxide adduct in the presence of hydrogen and ammonia to form a polyetheramine.
[0104] The reaction for producing PIB-PEAA often produces a PIB-PEAA composition, wherein the main component of the composition, i.e., more than 50 mol%, preferably more than 60 mol%, more preferably higher than 70 mol%, and even more preferably higher than 80 mol%, and most preferably more than 90 mol%, is PIB-PEAA. Minor components present in the composition may include isomers of polyetheramines, unreacted polyisobutylene epoxides, and byproducts from the isobutylene-initiated epoxidation reaction, such as mixtures of alcohols, aldehydes, and unreacted polyisobutylene, and very small amounts (if detectable) of monosubstituted polyisobutylamines, which constitute less than 2 mol% of the PIB-PEAA composition, typically less than 1 mol% to 0 or undetectable.
[0105] diluent Due to the high viscosity of polyisobutylene epoxide, it is desirable that the amination reaction be carried out in the presence of at least one hydrocarbon diluent. It is believed that when the viscosity is too high, reactive sites are difficult to access, and the desired reactants are difficult to diffuse to the reactive sites.
[0106] The desired diluent should be stable and non-reactive to the reactants and the resulting end product (PIB-PEAA). In one embodiment, at least one diluent is selected from benzene, toluene, xylene; saturated aliphatic hydrocarbons such as pentane, hexane, heptane; paraffinic, cycloalkanes, aromatic base oils, for example known from Group I, II, III, IV, or V, including polyalphaolefins or any other compound that affects the viscosity of the reaction.
[0107] In a preferred embodiment, at least one diluent may be used in the reaction between polyisobutylene epoxide and hydrophilic polyetheramine to improve (in addition to) the solubility and miscibility in the process. In one embodiment, the at least one diluent is selected from benzene, toluene, xylene; saturated aliphatic hydrocarbons such as pentane, hexane, heptane; paraffinic, cycloalkanes, aromatic base oils, for example known from Group I, II, III, IV or V, including polyalphaolefins or any other compound that affects the viscosity of the reaction.
[0108] The best diluents are those that are easily removed from the final products (toluene, heptane, etc.) or those that remain in the final mixture (i.e., base oil or PAO).
[0109] catalyst Optionally, a catalyst may be used in the process of the present invention to accelerate the reaction rate and improve the overall conversion rate of the PIB-PEAA product to the composition. Such catalysts are well known in the art and are used depending on the process, reactor configuration, reaction conditions, monomers, etc. Non-limiting examples of suitable catalysts include Lewis acids such as aluminum trichloroethylene, boron trifluoroethylene, titanium tetrachloroethylene, and ferric chloride, used alone or as a base adduct such as BF3:ether, BF3:alcohol, or solid catalysts containing both Lewis acid and Brønsted acid moieties, such as silica, silica-alumina, and organic acids and water, such as acetic acid and water.
[0110] In another embodiment, optionally, a Lewis acid or Brønsted acid catalyst may be used, selected to form one or more of aluminum trichlorochloro, boron trifluoro, titanium tetrachloro, and ferric chloride; BF3: ether, BF3: alcohol; or a solid catalyst containing Lewis acid and Brønsted acid moieties, such as silica, silica-alumina, or organic acid and water.
[0111] Based on the total weight of the polyolefin epoxide, the amount of catalyst is typically from about 0.05 to about 10 wt%, preferably from about 0.1 to about 10 wt%. The optimal catalyst is a Lewis acid such as boron trifluoride.
[0112] proton solvent In practice, the catalyst is used in combination with or alone with a protic solvent. In another embodiment, at least one protic solvent is used in the reaction between polyisobutylene epoxide, polyetheramine, and diluent, with or without a catalyst. In one embodiment, the at least one protic solvent is preferably at least one organic hydroxyl compound, preferably an alcohol or water, with the most preferred alcohol being methanol or ethanol. The amount of protic solvent used is typically less than 1% by weight, based on the weight of the polyisobutylene epoxide.
[0113] In another preferred embodiment, at least one proton solvent is used in the reaction between polyisobutylene epoxide, polyetheramine, and a proton solvent, with or without a catalyst. In one embodiment, the at least one proton solvent is preferably at least one organic hydroxyl compound, preferably an alcohol or water, with the most preferred alcohol being methanol or ethanol. It is believed that when a catalyst is used in combination with a proton solvent, the proton solvent acts as an initiator of the reaction.
[0114] Reactor and conditions Reaction conditions may vary depending on the type and configuration of the reactor, as is known to those skilled in the art. In one embodiment, a batch or continuous process is used to produce PIB-PEAA, wherein in a reactor, preferably jacketed, the reactor is heated and stirred to a specific temperature and pressure, PIBEP is introduced into the reactor in the presence of a diluent (if used), followed by the introduction of a polyetheramine along with a catalyst and optionally a protic solvent.

[0149] Test Analysis and Solution The ethylene oxide number of polyisobutylene epoxide (PIB epoxide or PIBEP) is determined using ASTM Test Method D 1652. The quantitative determination of polyisobutylene polyetheramine is based on the stoichiometry of the reagents used, along with... 1 H and 13 Both C and NMR. (By means) 1H NMR is used to determine the amount of unreacted polyisobutylene epoxide, in addition to any additional "free" unsubstituted PIB moiety. This method also quantifies the rearrangement of polyisobutylene epoxide into polyisobutylene vinyl alcohol without reaction with the polyetheramine. The presence of any unreacted primary polyetheramine can be determined by the presence of the CH group and the nearest CH3 group adjacent to the primary polyetheramine. 13 The C NMR peaks determine this. Any unreacted primary polyetheramines may indicate the presence of monoisobutylene polyetheramines or amines that did not participate in the reaction.
[0150] The products are as follows: 1 H NMR and 13 C10 NMR characterization: NMR spectra were recorded at ambient temperature on a Bruker 600 MHz Neo Digital NMR Spectrometer. All chemical shifts were referenced to tetramethylsilane (TMS) as an external standard and CDCl3 as a reference solvent. δ H 7.24 ppm and δ C Residual proton and carbon atom signals of 77.0 ppm. Samples were prepared at 60–100 mg in 0.5 mL of CDCl3 (Sigma Aldrich). Spectra were analyzed by Fourier transform and phase and baseline corrections were performed using the Bruker TopSpin (version 4.0.7) automated program. All spectra were manually integrated and normalized to selected peaks for the desired peak integration. The integration region was at least 25 times the peak linewidth (Hz) in both directions, and the peak integration data were the average of three separate manual measurements to minimize experimental uncertainty.
