[0002] Cross-reference to related applications
[0003] This application claims the benefit and priority of U.S. Provisional Application No. 63 / 561,632, filed March 5, 2024, the disclosure of which is incorporated herein by reference. Technical Field
[0004] This disclosure relates to catalyst compounds, catalyst systems comprising such compounds, and their uses. Background Technology
[0005] Polyolefin materials are widely used in industrial and commercial applications. These materials are ubiquitous in society in a variety of forms, from plastic containers and foodstuffs to various components for automobiles and engineering equipment. The widespread use and application of polyolefin materials highlights the economic incentives for the mass production of these polymers through industrially scalable processes.
[0006] In the field of polyolefin materials, the most commonly associated polymer is polyethylene (PE). Different methods of PE synthesis can be specifically designed to guide materials to exhibit different macromolecular characteristics and physical properties, as exemplified by the production of low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), and high-density polyethylene (HDPE). Furthermore, various polymerization methods can be extended to other olefin monomer systems to produce polymers with diverse chemical compositions, molecular weights, polydispersity, stereoregularity, crystallinity, physical properties, and thermal properties.
[0007] In some cases, it is desirable to controllably adjust and / or regulate various chemical, macromolecular, and physical properties of polyolefin materials to meet specific objectives. Therefore, considerable interest and research have been directed towards developing novel catalyst systems for polyolefin synthesis. Such catalyst systems typically contain at least a catalyst complex and an activator compound. When implemented in polyolefin synthesis, the composition of the catalyst system should be carefully considered, as it can influence various properties of the resulting polyolefin. Furthermore, when developing new olefin polymerization catalyst systems, aspects of the catalyst composition (e.g., catalyst activity, chemical resistance, thermal stability, chemical stability, and shelf life) should be considered.
[0008] Typically, in the synthesis of polyolefins, olefin monomers are contacted with a catalyst system via one or more gas-phase, solution-phase, and bulk-phase polymerization methods. However, it is important to consider that the polymerization should be industrially feasible, producing large quantities of polyolefins with high productivity (e.g., catalyst activity). Additionally, it is desirable to produce polyolefins with higher molecular weights to meet the physical property requirements associated with the intended application.
[0009] While there are reports of catalyst systems capable of producing high molecular weight polyolefins, the resulting polymer materials typically have high molecular weights and broad molecular weight distributions, and therefore may often be difficult to process due to the hardness provided by the small amount of extremely high molecular weight polymer components in the produced polyolefin product. Furthermore, such catalyst systems typically exhibit low catalytic activity (e.g., polymer yield per time period).
[0010] Therefore, there is a need to develop new catalyst compounds and systems that possess high catalytic activity and the ability to form high molecular weight polyolefins without adversely affecting material properties and processability.

[0246]
[0247] catalyst system
[0248] In this article, the terms "co-catalyst" and "activator" are used interchangeably.
[0249] The catalyst system described herein may comprise the catalyst complexes and activators described above, such as aluminoxanes or noncoordinate anions, and may be formed by combining the catalyst components described herein with the activator in any manner known in the art (including optionally combining the catalyst and activator with a support (e.g., silica)). The catalyst system may also be added to or generated in solution polymerization or bulk polymerization (in monomers). The catalyst system disclosed herein may have one or more activators and one, two, or more catalyst compounds. An activator is defined as any compound that can activate any of the catalyst compounds described above by converting a neutral metal compound into a catalytically active metal compound cation. Non-limiting activators may include, for example, aluminoxanes, alkylaluminum, ionized activators (which may be neutral or ionic), and conventional types of co-catalysts. Suitable activators may include aluminoxane compounds, modified aluminoxane compounds, and ionized anion precursor compounds that abstract reactive, α-bound metal ligands, such that the metal compound becomes a cationized and charge-balanced noncoordinate or weakly coordinated anion, such as a noncoordinate anion.
[0250] In at least one embodiment, the catalyst system comprises one or more catalyst compounds and activator compounds represented by formulas (I), (II), (III), (IV), and (V) above. The activator compounds may include, but are not limited to, aluminoxane catalysts and ionized / non-coordinated anionic activators.
[0251] Aluminoxane activator
[0252] Aluminoxane activators are used as activators in the catalyst systems described herein. Aluminoxanes are typically oligomers containing -Al(Ra”)-O- subunits, where Ra”’’ is an alkyl group. Examples of aluminoxanes include methylaluminoxane (MAO), modified methylaluminoxane (MMAO), ethylaluminoxane, and isobutylaluminoxane. Alkylaluminoxanes and modified alkylaluminoxanes are suitable as catalyst activators, particularly when the abstractable ligand is alkyl, halogen, alkoxy, or amino (amide). Mixtures of different aluminoxanes and modified aluminoxanes can also be used. Visually clear methylaluminoxanes are preferred. Turbid or gelled aluminoxanes can be filtered to produce a clear solution, or clear aluminoxane can be decanted from a turbid solution. A useful aluminoxane is modified methylaluminoxane (MMAO) cocatalyst type 3A (commercially available under the trade name Modified Methylalumoxane type 3A from Akzo). Chemicals, Inc. (which is included in U.S. Patent No. 5,041,584, which is incorporated herein by reference). Other available aluminoxanes are solid polymethylaluminoxanes as described in U.S. Patent Nos. 9,340,630, 8,404,880, and 8,975,209, which are incorporated herein by reference.
[0253] When the activator is an aluminoxane (modified or unmodified), at least one embodiment selects a maximum amount of activator of up to 5,000 molar excess Al / M of catalyst compound (per metal catalytic site). The minimum activator-to-catalyst compound ratio can be 1:1 molar ratio. Possible ranges include about 1:1 to about 500:1, for example about 1:1 to about 200:1, for example about 1:1 to about 100:1, for example about 1:1 to about 50:1.
[0254] In alternative embodiments, a small amount or no aluminoxane is used in the polymerization method described herein. For example, the aluminoxane may be present at zero molar %, or alternatively, the aluminoxane may be present at a molar ratio of aluminum to the transition metal of the catalyst compound of less than about 500:1, for example less than about 300:1, for example less than about 100:1, for example less than about 1:1.
[0255] Ionized / noncoordinated anion activators
[0256] The term "noncoordinate anion" (NCA) means an anion that does not coordinate with a cation or only weakly coordinates to a cation, thus retaining sufficient activity to be replaced by a Lewis base. "Compatible" noncoordinate anions are those that do not degrade to neutral when the initially formed complex decomposes. Furthermore, the anion does not transfer anionic substituents or fragments to the cation, resulting in the formation of neutral transition metal compounds and neutral byproducts from the anion. Noncoordinate anions useful according to this disclosure are those that are compatible, stabilize transition metal cations (in the sense of balancing the ionic charge of the transition metal cation to +1), and still retain sufficient activity to allow substitution during polymerization. Ionizing activators available herein typically include NCAs, particularly compatible NCAs.
[0257] In some embodiments, the activator is an ionized activator, neutral or ionic. In some embodiments of this disclosure, the neutral or ionic activator may be used alone or in combination with an aluminoxane or modified aluminoxane activator.
[0258] In some embodiments, the catalyst system of this disclosure may comprise at least one noncoordinate anionic (NCA) activator. In at least one embodiment, a boron-containing NCA activator may be used, wherein the boron-containing NCA activator is represented by the following formula:

These films can be formed by any number of known extrusion or co-extrusion techniques (e.g., blown bubble film processing techniques), wherein the composition can be extruded in a molten state through an annular die and then expanded to form a uniaxially or biaxially oriented melt, which is then cooled to form a tubular blown film, which can then be axially cut and unfolded to form a flat film. The film can subsequently be non-oriented, uniaxially oriented, or biaxially oriented to the same or different degrees. One or more layers of the film can be oriented to the same or different degrees in the transverse and / or longitudinal directions. Uniaxial orientation can be accomplished by using conventional cold stretching or hot stretching methods.

For example, a polyethylene layer can be extruded, coated, or laminated onto an oriented polypropylene layer, or polyethylene and polypropylene can be co-extruded together into a film and then oriented. Similarly, oriented polypropylene can be laminated onto oriented polyethylene, or oriented polyethylene can be coated onto polypropylene, and then optionally the combination can be further oriented. For example, the film can be oriented in the longitudinal (MD) direction at a ratio of up to 15, for example, about 5 to about 7, and in the transverse (TD) direction at a ratio of up to 15, for example, about 7 to about 9.

[0488] Aggregate Examples
[0489] A solution of the precatalyst was prepared using toluene (ExxonMobil Chemical - anhydrous, stored under N2) (98%). The precatalyst solution was typically 0.5 mmol / L.
[0490] Solvents, polymerization-grade toluene, and / or isohexane were supplied by ExxonMobil Chemical Co. and purified by passing through a series of columns: two 500cc Oxyclear tubes in series from Labclear (Oakland, Calif.), followed by two 500cc columns in series packed with dry 3Å molecular sieves (8-12 mesh; Aldrich Chemical Company), and two 500cc columns in series packed with dry 5Å molecular sieves (8-12 mesh; Aldrich Chemical Company).
[0491] 1-Octenene (C8; 98%, Aldrich Chemical Company) was dried by stirring overnight on NaK and then filtering through alkaline alumina (Aldrich Chemical Company, Brockman Basic 1).
[0492] Polymer-grade ethylene (C2) was used and further purified by passing it through a series of columns: a 500cc Oxyclear tube from Labclear (Oakland, Calif.), followed by a 500cc column packed with dry 3Å molecular sieves (8-12 mesh; Aldrich Chemical Company), and a 500cc column packed with dry 5Å molecular sieves (8-12 mesh; Aldrich Chemical Company).
[0493] Polymer-grade propylene (C3) was used and further purified by passing it through a series of columns: a 2250cc Oxiclear tube from Labclear, followed by a 2250cc column packed with 3Å molecular sieves (8-12 mesh; Aldrich Chemical Company), then two 500cc columns in series packed with 5Å molecular sieves (8-12 mesh; Aldrich Chemical Company), then a 500cc column packed with Selexsorb CD (BASF), and finally a 500cc column packed with Selexsorb COS (BASF).
[0494] Activation of the precatalyst was performed using methylaluminoxane (MAO, 10 wt% in toluene, Albemarle Corp.; ActID=M) or dimethylphenylammonium tetra(perfluorophenyl)borate (Boulder Scientific or Albemarle Corp.; ActID=D). MAO was used as a 0.5 wt% or 1.0 wt% solution in toluene. The micromolar numbers of MAO reported in the experimental section are based on the micromolar numbers of aluminum in MAO. The molecular weight of MAO is 58.0 g / mol. Dimethylphenylammonium tetra(perfluorophenyl)borate was typically used as a 0.5 mmol / L solution in toluene.
[0495] For polymerization operations using dimethylphenylammonium tetra(perfluorophenyl)borate, tri-n-octylaluminum (TnOAl, pure, AkzoNobel) is used as a scavenger before introducing the activator and pre-catalyst into the reactor. TnOAl is typically used as a 5 mmol / L solution in toluene.
[0496] Reactor description and preparation :
[0497] Polymerization was carried out in an autoclave equipped with an external heater for temperature control, a glass insert (reactor internal volume = 23.5 mL for C2 and C2 / C8; 22.5 mL for C3 operation), a diaphragm inlet, controlled nitrogen, ethylene, and propylene supply, and a disposable PEEK mechanical stirrer (800 RPM) in an inert atmosphere (N2) drying chamber. The autoclave was prepared by purging with dry nitrogen at 110°C or 115°C for 5 hours, followed by purging at 25°C for 5 hours.
[0498] Ethylene polymerization (PE) or ethylene / 1-octene copolymerization (EO) :
[0499] Prepare the reactor as described above, then purge with ethylene. For MAO (Act ID=M) activation, add toluene, 1-octene (0.100 mL for use), and activator (MAO) via syringe at room temperature and atmospheric pressure. Then bring the reactor to the process temperature (80°C) and charge with ethylene to the process pressure (75 psig = 618.5 kPa or 200 psig = 1480.3 kPa) while stirring at 800 RPM. Then add the pre-catalyst solution to the reactor via syringe under process conditions. For dimethylphenylammonium tetrafluorophenylborate (Act ID=D) activation, add toluene, 1-octene (100 μL for use), and tris(n-octyl)aluminum scavenger (TnOAl, 0.5 μmol) via syringe at room temperature and atmospheric pressure. The reactor was then brought to the process temperature (80°C) and charged with ethylene to the process pressure (75 psig = 618.5 kPa or 200 psig = 1480.3 kPa) while stirring at 800 RPM. The activator solution, followed by the pre-catalyst solution, was then injected into the reactor via a syringe under process conditions. During polymerization, ethylene was introduced into the autoclave (using a computer-controlled solenoid valve) to maintain the reactor gauge pressure (+ / - 2 psig). The reactor temperature was monitored and typically maintained within + / - 1°C. Polymerization was stopped by adding approximately 50 psi of compressed dry air gas mixture to the autoclave for approximately 30 seconds. Polymerization was quenched after the predetermined cumulative amount of ethylene had been added (maximum quenching value psid) or after a maximum of 30 minutes of polymerization time. The reactor was then cooled and vented. The polymer was separated after removing the solvent under vacuum. The reported yield includes the total weight of polymer and residual catalyst. Catalyst activity is reported as grams of polymer per mmol of transition metal compound per hour of reaction time (g / mmol·hr). The ethylene homopolymerization and ethylene / 1-octene copolymerization operations are summarized in Table 1.
[0500] Polypropylene (PP) :
[0501] Prepare the reactor as described above, then heat it to 40°C and purge it with propylene gas at atmospheric pressure. For MAO activation, add toluene or isohexane, MAO, and liquid propylene (1.0 mL) via a syringe. Then heat the reactor to the process temperature (70°C or 100°C) while stirring at 800 RPM. Add the pre-catalyst solution via a syringe while the reactor is under process conditions. For dimethylphenylammonium tetrafluorophenyl borate activation, add toluene or isohexane, liquid propylene (1.0 mL), and tris(n-octyl)aluminum scavenger (TnOAl, 0.5 μmol) via a syringe. Then bring the reactor to the process temperature (70°C or 100°C) while stirring at 800 RPM. Inject the activator solution, followed by the pre-catalyst solution, into the reactor via a syringe under process conditions. Monitor the reactor temperature and typically maintain it within + / - 1°C. Stop the polymerization by adding a mixture of approximately 50 psi of compressed dry air to the autoclave for approximately 30 seconds. The polymerization was quenched based on a predetermined pressure loss of 8 psid (maximum quenching value) or a maximum of 30 minutes. The reactor was then cooled and evacuated. The polymer was separated after the solvent was removed under vacuum. The actual quenching time (s) is reported as quenching time (s). The reported yield includes the total weight of polymer and residual catalyst. Catalyst activity is reported as grams of polymer per mmol of transition metal compound per hour of reaction time (g / mmol·hr). Examples of propylene homopolymerization are reported in Table 2.
[0502] Polymer characterization
[0503] For analytical testing, a polymer sample solution was prepared by dissolving the polymer in 1,2,4-trichlorobenzene (TCB, 99+% purity, from Sigma-Aldrich) containing 2,6-di-tert-butyl-4-methylphenol (BHT, 99%, from Aldrich) at 165°C for approximately 3 hours. Typical polymer concentrations in the solution ranged from 0.1 to 0.9 mg / mL, and BHT concentrations were 1.25 mg BHT / mL TCB. The sample was then cooled to 135°C for testing.
[0504] High-temperature size exclusion chromatography was performed using an automated “rapid GPC” system as described in U.S. Patents 6,491,816; 6,491,823; 6,475,391; 6,461,515; 6,436,292; 6,406,632; 6,175,409; 6,454,947; 6,260,407; and 6,294,388, each of which is incorporated herein by reference. Molecular weight (weight-average molecular weight (Mw) and number-average molecular weight (Mn)) and molecular weight distribution (MWD = Mw / Mn), also known as polymer polydispersity (PDI), were measured by gel permeation chromatography using a Symyx Technology GPC equipped with an evaporative light scattering detector (ELSD) and calibrated with polystyrene standards (Polymer Laboratories: Polystyrene Calibration Kit SM-10: Mp (peak Mw) from 5,000 to 3,390,000). Alternatively, samples were measured by gel permeation chromatography using a Symyx Technology GPC equipped with a dual-wavelength infrared detector and calibrated with polystyrene standards (Polymer Laboratories: Polystyrene Calibration Kit SM-10: Mp (peak Mw) 580 to 3,039,000). Samples were run using three Polymer Laboratories: PLgel 10μm Mixed-B 300x7.5mm columns in tandem at an elution rate of 2.0 mL / min (sample temperature 135°C, oven 165°C / column) (injecting 250 μL of polymer solution from TCB into the system). Column diffusion correction was not employed. Epoch, available from Symyx Technologies, was used. ® Numerical analysis can be performed using Automation Studio software available from Freeslate. The obtained molecular weights are relative to linear polystyrene standards. Molecular weight data are reported in Tables 1 and 2 under the headings Mn, Mw, Mz, and PDI as defined above.
[0505] Differential scanning calorimetry (DSC) measurements were performed on a TA-Q100 instrument to determine the melting point of the polymer. The sample was pre-annealed at 220 °C for 15 min and then allowed to cool to room temperature overnight. The sample was then heated to 220 °C at a rate of 100 °C / min and then cooled at a rate of 50 °C / min. Melting points were collected during heating. The results are reported in Tables 1 and 2 under the heading Tm (°C).
[0506] Samples for infrared analysis were prepared by depositing a stabilized polymer solution onto a silanized wafer (part number S10860, Symyx). Approximately 0.12 to 0.24 mg of polymer was deposited on the wafer unit using this method. The samples were then analyzed on a Brucker Equinox 55FTIR spectrometer equipped with a Pikes' MappIR specular reflection sample accessory. The analysis was performed at 2 cm⁻¹. -1 Data was collected at a resolution of 32 scans covering a depth of 5000 cm. -1 Up to 500cm -1 The spectrum of the spectral range.
[0507] For ethylene-1-octene copolymer, measurements were taken at ~1375 cm⁻¹. -1 The methyl deformation at the position determines the weight percentage of octene in the copolymer. This is achieved through combination and overtone bands (~4321 cm⁻¹). -1 The peak height of this band is normalized (at the location), which corrects for path length differences. The normalized peak height is then compared with that from... 1 Individual calibration curves of H NMR data were correlated to predict the wt% octene content in the concentration range of ~2 wt% to 35 wt% octene. Typically, an R-value of 0.98 or greater is achieved. 2 Relevance. These figures are reported in Table 1 under heading C8 weight %
[0508] The aggregation results are collected in Tables 1 and 2 below. “Ex#” represents the instance number. Under the Ex# column heading, the following abbreviations are defined:
[0509] PE = Polyethylene, EO = Ethylene-1-octene copolymer, PP = Polypropylene, CPE = Comparative Polyethylene, CEO = Comparative Ethylene-1-octene copolymer
[0510] CPP = Comparative polypropylene. Examples beginning with "C", such as CPP and CPE, are comparative examples. "Cat ID" indicates the precatalyst used in the experiment. The corresponding number indicates that the precatalyst (also referred to as a precatalyst, complex, or compound) is located in the synthesis experiment section. "Cat (μmol)" is the amount of precatalyst added to the reactor. For all experiments using dimethylphenylammonium tetra(perfluorophenyl)borate (Act ID = D), the molar ratio of activator / precatalyst is 1.1. For all experiments using MAO (Act ID = M) as the activator, a molar ratio of 500 Al / M is used unless otherwise specified. T (°C) is the polymerization temperature, typically maintained within ±1°C. "Yield" is the polymer yield and is not corrected for catalyst residue. "Quenching time (s)" is the actual duration of the polymerization run in seconds. For ethylene-based polymerization runs, "Quenching value (psid)" is the set maximum (conversion) amount of ethylene absorption in the experiment. If the polymerization quenching time is less than the set maximum time, polymerization continues until the set maximum amount of ethylene absorption is reached. For propylene homopolymer operation, the quench value represents the maximum set pressure loss (conversion) of propylene (for PP operation) during polymerization. Activity is reported as grams of polymer per mmol of catalyst per hour.
[0511] Table 1. Examples of ethylene homopolymerization and ethylene / 1-octene copolymerization
[0512] General reaction conditions The total solvent volume, including catalyst, activator, and diluent, is 5.0 ml toluene (for ethylene homopolymerization) and 4.9 ml toluene (for ethylene-octene copolymerization), with 0.1 mL 1-octene (shown in the table in microliters (µL)); 25 nmol pre-catalyst and 500 equivalents of Act ID M or 1.1 equivalents of Act ID D; polymerization temperature of 80 °C; ethylene absorption at 75 or 200 psi; when using 75 psi ethylene, the quenching value is set to 20 psid ethylene absorption, and when using 200 psi ethylene, the quenching value is set to 15 psid ethylene absorption, or a maximum time of 30 minutes. This indicates that the reported FTIR value is outside the calibration range.

The catalyst compounds of this disclosure can provide high molecular weight polymers with high catalytic activity, which can be used in commercial polymer production.
[0548] Unless otherwise stated, the phrases "consist essentially of" and "consisting essentially of" do not exclude the presence of other steps, elements, or materials, whether or not they are specifically mentioned in this specification, provided that such steps, elements, or materials do not affect the essential and novel features of this disclosure. Furthermore, they do not exclude impurities and variations commonly associated with the elements and materials used.
[0549] For the sake of brevity, only certain ranges are explicitly disclosed in this document. However, a range derived from any lower limit can be combined with any upper limit to describe an unspecified range, and a range derived from any lower limit can be combined with any other lower limit to describe an unspecified range; similarly, a range derived from any upper limit can be combined with any other upper limit to describe an unspecified range. Furthermore, a range includes every point or individual value between its endpoints, even if not explicitly stated. Thus, each point or individual value can serve as its own lower or upper limit, combined with any other point or individual value or any other lower or upper limit, to describe an unspecified range.
[0550] All references cited herein are incorporated herein by reference, including any priority documents and / or testing procedures, provided they are not inconsistent with this text. As will be apparent from the foregoing general description and specific embodiments, various modifications may be made without departing from the spirit and scope of this disclosure, despite the form described and illustrated herein. Therefore, this disclosure is not intended to be limited thereto. Similarly, for the purposes of U.S. law, the term “comprising” is considered synonymous with the term “including.” Likewise, whenever the transitional phrase “comprising” precedes a composition, element, or group of elements, it should be understood that we also contemplate the same composition or group of elements preceding the description of the composition, element, or plurality of elements with the transitional phrases “substantially constitutes,” “consisting of,” “selected from,” or “is,” and vice versa.
[0551] Although this disclosure has been described with respect to various embodiments and examples, those skilled in the art who benefit from this disclosure will understand that other embodiments can be devised without departing from the scope and spirit of this disclosure.
