Description

Technical Field

[0001] Cross - Reference to Related Applications This application claims the benefit and priority of U.S. Provisional Application No. 63 / 338,167, filed on May 4, 2022, the disclosure of which is incorporated herein by reference. The present disclosure relates to bis(arylphenolate) Lewis base transition metal complexes, catalyst systems comprising bis(arylphenolate) Lewis base transition metal complexes, and polymerization processes for producing polyolefin polymers such as polyethylene - based polymers and polypropylene - based polymers.

Background Art

[0002] Polyolefins such as polyethylene typically have comonomers such as hexene incorporated into the polyethylene backbone. These copolymers provide various physical properties compared to polyethylene alone and are typically produced in low - pressure reactors using, for example, solution polymerization, slurry polymerization, or gas - phase polymerization processes. The polymerization can be carried out in the presence of a catalyst system such as a Ziegler - Natta catalyst, a chromium - based catalyst, or a catalyst system using a metallocene catalyst. Furthermore, since pre-catalysts (neutral, non-activated complexes) are often stored for several weeks before use, the pre-catalysts should be thermally stable at ambient temperature and above. The performance of a given catalyst is closely affected by reaction conditions such as monomer concentration and temperature. For example, solution processes that offer advantages due to being carried out at temperatures above 120 °C are, in particular, a challenge for catalyst development. At such high reactor temperatures, both high catalyst activity and high molecular weight capabilities decline very consistently with increasing reactor temperature, so it is often difficult to maintain high catalyst activity and high molecular weight capabilities. For a wide range of desired polyolefin products ranging from high-density polyethylene (HDPE) to elastomers (e.g., thermoplastic elastomers (TPE); ethylene-propylene-diene (EPDM)), a single catalyst is likely to be unable to address all that is required for the production of these various polyolefin products, so a number of different catalyst systems may be required. Due to the strict set of requirements necessary for the development and production of new polyolefin products, the effort to identify a catalyst suitable for a given product and production process is very difficult.

[0003] Aromatic solvents are typically used to dissolve catalyst components in industrial olefin polymerization processes. However, usually, the solubility of catalyst components in non-aromatic solvents is poor, so replacing aromatic solvents with non-aromatic solvents such as isohexane is a challenge. Further information on the general state of the art regarding non-metallocene olefin polymerization catalysts can be found in Baier, M. C. (2014) “Post-Metallocenes in the Industrial Production of Poly-olefins,” Angew. Chem. Int. Ed., v.53, pp. 9722-9744, the entire contents of which are incorporated herein by reference.

[0004] Further information regarding the complex can be found in Goryunov, G. P. et al. (2021) “Rigid Postmetallocene Catalysts for Propylene Polymerization: Ligand Design Prevents the Temperature-Dependent Loss of Stereo- and Regioselectivities,” ACS Catalysis, v.11(13), pp. 8079-8086; US2020 / 0255556; US2020 / 0255555; US2020 / 0254431; and US2020 / 0255553, each of which is incorporated herein by reference in its entirety.

Embodiments for Carrying Out the Invention

[0007] Exemplary embodiments of the industrial progress of the present invention include pyridine-2,6-bis(phenylene phenolate) complexes that are useful as catalyst components for olefin polymerization and have improved solubility in non-aromatic hydrocarbons (e.g., isohexane). The improved solubility of these complexes was achieved by modifying the ligand framework that provides improved solubility at specific positions, but did not adversely affect the performance of this complex when used as a catalyst for olefin polymerization. For the purposes of this disclosure, the numbering scheme for groups of the periodic table is used as described in Chemical and Engineering News, v.63(5), pg. 27 (1985). Thus, "Group 4 metals" refers to the elements of Group 4 of the periodic table, e.g., Hf, Ti, or Zr. The following abbreviations may be used herein: Me is methyl, Et is ethyl, Ph is phenyl, tBu is tertiary butyl, MAO is methylalumoxane, NMR is nuclear magnetic resonance, t is time, s is second, h is hour, psi is pounds per square inch, psig is pounds per square inch gauge, equiv is equivalent, and RPM is revolutions per minute.

[0008] This specification describes transition metal complexes. The term complex is used to describe a molecule in which auxiliary ligands are coordinated to a central transition metal atom. The ligands are bulky and stably bound to the transition metal so as to maintain their influence during the use of the catalyst, such as polymerization. The ligands can be coordinated to the transition metal by covalent bonds and / or electron-donating coordination or intermediate bonds. Transition metal complexes are generally activated using an activator to exert their polymerization or oligomerization function. The activator, without being bound by theory, often generates a cation as a result of the removal of a leaving group and an anionic group often referred to as such from the transition metal. The terms "substituent", "radical", "group" and "moiety" may be used interchangeably. "Conversion rate" refers to the amount of monomer converted to the polymer product, reported as mol% and calculated based on the amount of polymer yield and the amount of monomer fed to the reactor.

[0009] "Catalytic activity" is a measure of how active a catalyst is, and is reported as the number of grams of product polymer (gP.mmolcat -1 .h -1 ) produced per millimole of catalyst (cat) per hour. The term "heteroatom" refers to any of the Group 13-17 elements excluding carbon. Heteroatoms can include B, Si, Ge, Sn, N, P, As, O, S, Se, Te, F, Cl, Br and I. The term "heteroatom" can include the above elements having attached hydrogen, e.g., BH, BH 2 , SiH 2 , OH, NH, NH 2 . The term "substituted heteroatom" describes a heteroatom in which one or more of these hydrogen atoms have been replaced by a hydrocarbyl group or a substituted hydrocarbyl group.

[0010] Unless otherwise indicated (e.g., definitions such as "substituted hydrocarbyl", "substituted aromatic", etc.), the term "substituted" means that at least one hydrogen atom is replaced by a hydrocarbyl group, a heteroatom, or a heteroatom-containing group, such as a halogen (e.g., Br, Cl, F, or I), or at least one functional group, such as -NR * 2 、-OR * 、-SeR * 、-TeR * 、-PR * 2 、-AsR * 2 、-SbR * 2 、-SR * 、-BR * 2 、-SiR * 3 、-GeR * 3 、-SnR * 3 、-PbR * 3 wherein each R * is independently a hydrocarbyl radical or a halocarbyl radical, and two or more R * may be joined together to form a substituted or unsubstituted, fully saturated, partially unsaturated, or aromatic cyclic or polycyclic ring structure, or at least one hydrogen atom is replaced by at least one non-hydrogen group such as those described above, or at least one heteroatom is inserted within the hydrocarbyl ring.

Examples of suitable thiolate radicals include methanethiolate, ethanethiolate, n-propanethiolate, iso-propanethiolate, n-butanethiolate, iso-butanethiolate, sec-butanethiolate, tert-butanethiolate, benzenethiolate. The term "aryl" or "aryl group" means an aromatic ring and its substituted variants, e.g., phenyl, 2-methyl-phenyl, xylyl, 4-bromo-xylyl. Similarly, heteroaryl means an aryl group in which a ring carbon atom (or two or three ring carbon atoms) is replaced by a heteroatom such as N, O, or S. As used herein, the term "aromatic" also refers to a pseudoaromatic heterocyclic group, a heterocyclic substituent having properties and structure (nearly planar) similar to those of an aromatic heterocyclic ligand but not falling within the definition of aromatic. Similarly, the term aromatic also refers to a substituted aromatic.

[0018] The term "arylalkyl" means an aryl group in which hydrogen is replaced by an alkyl group or a substituted alkyl group. For example, 3,5'-di-tert-butyl-phenylindenyl is indene substituted by an arylalkyl group. When an arylalkyl group is a substituent on another group, the arylalkyl group is bonded to that other group through the aryl. The term "alkylaryl" means an alkyl group in which hydrogen is replaced by an aryl group or a substituted aryl group. For example, phenethylindenyl is indene substituted by an ethyl group bonded to a benzene group. When an alkylaryl group is a substituent on another group, the alkylaryl group is bonded to that other group through the alkyl. The term "ring atom" means an atom that is part of a cyclic ring structure. By this definition, the benzyl group has 6 ring atoms and tetrahydrofuran has 5 ring atoms.

[0019] A heterocyclic ring is a ring having heteroatoms within the ring structure, as opposed to a ring in which hydrogen on a ring atom is replaced by a heteroatom. For example, tetrahydrofuran is a heterocyclic ring and 4-N,N-dimethylamino-phenyl is a heteroatom-substituted ring. Another example of a heterocyclic ring can include pyridine, imidazole, and thiazole.

[0020] The terms "hydrocarbyl radical", "hydrocarbyl group", or "hydrocarbyl" can be used interchangeably and are defined to mean a group consisting of only hydrogen atoms and carbon atoms. For example, a hydrocarbyl can be linear, branched, or cyclic, and in the case of cyclic, can be aromatic or non-aromatic, C 1 -C 100It can be a radical. Examples of such radicals include, but are not limited to, alkyl groups such as methyl, ethyl, propyl (e.g., n-propyl, isopropyl, cyclopropyl), butyl (e.g., n-butyl, isobutyl, sec-butyl, tert-butyl, cyclobutyl), pentyl (e.g., iso-amyl, cyclopentyl), hexyl (e.g., cyclohexyl), octyl (e.g., cyclooctyl), nonyl, decyl (e.g., adamantanyl), undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl, octadecyl, nonadecyl, eicosyl, henicosyl, docosyl, tricosyl, tetracosyl, pentacosyl, hexacosyl, heptacosyl, octacosyl, nonacosyl or tricontyl, and aryl groups such as phenyl, benzyl and naphthyl.

[0021] The terms "adamantyl" and "adamantanyl" may be used interchangeably. Unless otherwise indicated, "C m -C y " refers to the corresponding moiety containing the total number of carbon atoms from m to y. Thus, examples of "C 2 -C 40 substituted hydrocarbyl" without further definition include one or more heteroatom-containing groups containing additional carbon (e.g., -NR * 2 , -OR * , -SeR * , -TeR * , -PR * 2 , -AsR * 2 , -SbR * 2 , -SR * , -BR * 2 , -SiR * 3 , -GeR * 3 , -SnR * 3 , -PbR * 3 ) and are further substituted by C1 It can contain a hydrocarbyl group, and thus the resulting substituted hydrocarbyl moiety contains a total of 2 to 40 carbon atoms. As used herein, Mn is the number average molecular weight, Mw is the weight average molecular weight, Mz is the z average molecular weight, mass % is the mass percentage, and mol % is the mole percentage. The molecular weight distribution (MWD), also referred to as the polydispersity index (PDI), is defined as Mw divided by Mn. Unless otherwise specified, all molecular weight units (e.g., Mw, Mn, Mz) are in g / mol.

[0022] Unless otherwise indicated, as used herein, "high molecular weight" is defined as a number average molecular weight (Mn) value of 100,000 g / mol or greater. "Low molecular weight" is defined as an Mn value of less than 100,000 g / mol. Unless otherwise specified, all melting points (Tm) are the second melting point of differential scanning calorimetry (DSC).

[0023] The "catalyst system" is a combination consisting of at least one catalyst compound, at least one activator, an optional co-activator, and an optional support material. The terms "catalyst compound", "catalyst complex", "transition metal complex", "transition metal compound", "pre-catalyst compound", and "pre-catalyst complex" are used interchangeably. When the "catalyst system" is used to describe such a pair before activation, the "catalyst system" means an unactivated catalyst complex (pre-catalyst) together with an activator, which may be together with a co-activator. When the "catalyst system" is used to describe such a pair after activation, the "catalyst system" means an activated complex and an activator or a moiety that balances other charges. The transition metal compound may be neutral as in the pre-catalyst or a charged chemical species containing a counterion as in the activated catalyst system. For the purposes of the present disclosure and its claims, when the catalyst system is described as including the neutral stable form of the components, it is well understood by those skilled in the art that the ionic form of the components is in a form that reacts with the monomer to produce a polymer. A polymerization catalyst system is a catalyst system capable of polymerizing a monomer into a polymer. Further, the catalyst compounds and activators represented by the formulas herein are intended to include both the neutral and ionic forms of the catalyst compounds and activators.

[0024] In the description herein, the catalyst may be described as a catalyst, a catalyst precursor, a pre-catalyst compound, a catalyst compound, or a transition metal compound, and these terms are used interchangeably. The term "anionic ligand" refers to a negatively charged ligand that donates one or more pairs of electrons to a metal ion. The term "Lewis base" refers to a neutrally charged ligand that donates one or more pairs of electrons to a metal ion. Examples of Lewis bases include diethyl ether, trimethylamine, pyridine, tetrahydrofuran, dimethyl sulfide, and triphenylphosphine. The term "heterocyclic Lewis base" refers to a Lewis base that is also a heterocycle. Examples of heterocyclic Lewis bases include pyridine, imidazole, thiazole, and furan. A bis(arylphenolate) Lewis base ligand is a tridentate ligand that binds to a metal through two anionic donors (phenolate) and one heterocyclic Lewis base donor (e.g., a pyridinyl group). A bis(arylphenolate) heterocyclic ligand is a tridentate ligand that binds to a metal through two anionic donors (phenolate) and one heterocyclic Lewis base donor. The term "continuously" means a system that operates without interruption or stoppage. For example, a continuous process for producing a polymer is one in which reactants are continuously introduced into one or more reactors and the polymer product is continuously withdrawn.

[0054] Activators and optional scavengers, co-activators and chain transfer agents U.S. Patent Application No. 16 / 788,088 (Publication No. US2020 / 254431) describes an activator, an optional scavenger, an optional co-activator, and an optional chain transfer agent that can be used due to the industrial progress of the present invention. In particular, useful activators are also non-aromatic hydrocarbon-soluble activator compounds, such as N-methyl-4-nonadecyl-N-octadecylanilinium [tetrakis(pentafluorophenyl)borate], N-methyl-4-nonadecyl-N-octadecylanilinium [tetrakis(heptafluoronaphthalenyl)borate], N-methyl-N-octadecyl-4-(octadecyloxy)anilinium [tetrakis(pentafluorophenyl)borate], N-methyl-N-octadecyl-4-(octadecyloxy)anilinium [tetrakis(heptafluoronaphthalenyl)borate], N,N-di(tallow)methylammonium [tetrakis(pentafluorophenyl)borate], N,N-di(tallow)methylammonium [tetrakis(heptafluoronaphthalenyl)borate], N,N-di(octadecyl)methylammonium [tetrakis(pentafluorophenyl)borate], N,N-di(octadecyl)methylammonium [tetrakis(heptafluoronaphthalenyl)borate], N,N-di(hexadecyl)methylammonium [tetrakis(pentafluorophenyl)borate], N,N-di(hexadecyl)methylammonium [tetrakis(heptafluoronaphthalenyl)borate], N-octadecyl-N-hexadecylmethylammonium [tetrakis(pentafluorophenyl)borate], and N-octadecyl-N-hexadecylmethylammonium [tetrakis(heptafluoronaphthalenyl)borate], as described in PCT Application No. US2020 / 044865 (Publication No. WO2021 / 086467), U.S. Patent Application No. 16 / 394,174 (published as US2019 / 0330394), and PCT Application No. US2019 / 029056 (published as WO2019 / 210026).

[0055] It is preferred to use an activator that is soluble in the non-aromatic hydrocarbon solvent, but an activator that has poor solubility or is insoluble in the non-aromatic hydrocarbon solvent can be used. When used, these activators can be fed to the reactor as a slurry or as a solid. Particularly useful activators in this class include triphenylcarbenium tetrakis(pentafluorophenyl)borate, triphenylcarbenium tetrakis(perfluoronaphthyl)borate, N,N-dimethylanilinium tetrakis(pentafluorophenyl)borate, N,N-dimethylanilinium tetrakis(perfluoronaphthyl)borate, and the like.

[0056] A typical activator-to-catalyst ratio is a molar ratio of about 1:1. Alternative preferred ranges include 0.1:1 to 100:1, alternatively 0.5:1 to 200:1, alternatively 1:1 to 500:1, alternatively 1:1 to 1000:1. Particularly useful ranges are 0.5:1 to 10:1, preferably 1:1 to 1:10. Particularly useful optional scavengers or co-activators or chain transfer agents include, for example, trialkylaluminums such as triisobutylaluminum, tri-n-hexylaluminum, tri-n-octylaluminum, and dialkylzincs such as diethylzinc. Further, hydrocarbon-soluble aluminoxanes and modified aluminoxanes "free of" trimethylaluminum can be used or may be used.

[0057] Furthermore, one of ordinary skill in the art can select suitable known activators and optional scavengers or co-activators or chain transfer agents for that particular purpose without undue experimentation. Combinations of multiple activators can be used. Similarly, combinations of multiple optional scavengers or co-activators or chain transfer agents may be used.

[0058] Solvent The catalyst constituent components of the present invention can be used together with an aromatic solvent such as toluene. Preferably, however, the catalyst constituent components are absent when used in the polymerization process.

Preferred solvents can include normal paraffins (e.g., Norpar™ solvents available from ExxonMobil Chemical Company (Houston, TX)), isoparaffin solvents (e.g., Isopar™ solvents available from ExxonMobil Chemical Company (Houston, TX)), non-aromatic cyclic solvents (e.g., Nappar™ solvents available from ExxonMobil Chemical Company (Houston, TX)), and combinations thereof.

[0059] Preferably, the aliphatic hydrocarbon solvent is C 4 ~C 10 a linear, branched, or cyclic alkane. Alternatively, it is selected from C 5 ~C 8 linear, branched, or cyclic alkanes. Preferably, the aliphatic hydrocarbon solvent is substantially free of all aromatic solvents. Preferably, the solvent is substantially free of toluene. By "substantially free of all aromatic solvents such as toluene" is meant that the solvent contains substantially no aromatic solvents (e.g., present at 0 mol%, alternatively, present at less than 1 mol%), preferably the polymerization reaction and / or the resulting polymer contains no "detectable aromatic hydrocarbon solvents" such as toluene. Preferred aliphatic hydrocarbon solvents include, in addition to commercially available solvent mixtures such as Nappar6 (trademark) and IsoparE (trademark), isohexane, cyclohexane, methylcyclohexane, pentane, isopentane, heptane, and combinations thereof. However, one of ordinary skill in the art can select other suitable non-aromatic hydrocarbon solvents without undue experimentation. Highly preferred aliphatic hydrocarbon solvents include isohexane, methylcyclohexane, and commercially available solvent mixtures such as Nappar6 (trademark) and IsoparE (trademark).

Chemical Structure

[0180] Complex solubility General considerations: The solubility study for complex 2 was carried out using the recrystallized material. The solubility study for all other complexes was carried out using the synthesized material. Complex 2 was co-crystallized with 1.4 equivalents of methylcyclohexane. Complex 3 was isolated containing 1 equivalent of pentane. Complex 4 was isolated containing 0.18 equivalents of hexane and 0.96 equivalents of toluene. Complex 6 was isolated containing 0.75 equivalents of pentane. Complex 8 was isolated containing 0.5 equivalents of pentane. Complex 14 was isolated containing 1 equivalent of isohexane. Complex 16 was isolated containing 0.39 equivalents of toluene. Complex 20 was isolated containing 2.63 equivalents of hexane and 0.28 equivalents of toluene. Complex 24 was isolated containing 0.69 equivalents of hexane. Complex 25 was isolated containing 1.14 equivalents of hexane. Nitrogen was bubbled through the solvents used (for 30 - 60 minutes) and dehydrated with 3 Å molecular sieves. Unless otherwise specified, all measurements were carried out at ambient temperature (20 °C - 25 °C). General procedure: Solubility was determined using either Method 1 or Method 2 below. For calculations, a value of 0.672 g / mL was used for the density of isohexane.

[0181] Method 1: A small amount of the complex (the actual mass recorded including any residual solvents as specified above, typically 5 - 30 mg) was loaded into a tared vial. Next, a small stir bar (8 mm) was added. Then, the solvent was added and the mixture was stirred rapidly (1000 rpm). If a homogeneous mixture was not formed within 30 minutes, additional solvent was added and the mixture was stirred for an additional 30 minutes. This process was repeated until either a clear solution (no visible solids or turbidity) was obtained or the vial was full. When the mixture approached homogeneity (i.e., little residual solid was observed), the amount of added solvent was maintained at a small amount (<1 mL) to minimize the excess over the solvent necessary to achieve homogeneity. Next, the stir bar was removed and the mass of the mixture was measured. If a clear solution was formed, the solubility of the complex was calculated as a single value based on the mass of the complex and the amount of solvent added to achieve the homogeneous solution. If the mixture was still in a heterogeneous state (visible solids or turbidity), the reported value was indicated as "less than" the calculated value.

[0182] Method 2: The measured amount of the complex (the actual mass recorded including any residual solvents as specified above) was added to a tared vial, and then a stir bar was added. Dry isohexane was added in small portions, and after each portion of isohexane, the resulting mixture was stirred. If a clear solution was formed, the solubility was reported as the range between the lower boundary value of the solubility calculated using all the solvent added to achieve the homogeneous solution and the higher boundary value of the solubility calculated using all the solvent measured before achieving the homogeneous solution. If the mixture was still in a heterogeneous (visible solids or turbidity) state, the solubility of the higher boundary value was calculated using all the solvent added. The equations used to calculate the solubility are listed below. The solvent present in the complex is included in the mass and formula weight of the complex. Solubility (mM) = [10 6 * [(grams of complex) / (formula mass of complex (g / mol))] / [(total volume of solvent (mL))] or Solubility (mM) = [10 6 * ​​[(Gram number of complex) / (formula mass of complex (g / mol))] / [(gram number of solvent) / (density of solvent (g / mL))] Solubility (mass %) =

[0184] Polymerization example Toluene (ExxonMobil Chemical - anhydrous, N 2 stored below) (98%) or isooctane (ExxonMobil Chemical - polymerization grade and purified as described below) was used to prepare a solution of the pre-catalyst. The pre-catalyst solution was typically 0.25 mmol / L. The polymerization grade toluene and / or isooctane used as the solvent was supplied by ExxonMobil Chemical Co. and purified by passing through a series of columns: two 500 cc Oxyclear cylinders in series made by Labclear (Oakland, Calif), then two 500 cc columns in series packed with dried 3 Å molecular sieves (8 - 12 mesh; Aldrich Chemical Company), and two 500 cc columns in series packed with dried 5 Å molecular sieves (8 - 12 mesh; Aldrich Chemical Company).

[0185] Polymerization grade propylene (C 3Using [[ID=]], a series of columns: a 2250 cc Oxiclear cylinder made by Labclear, then a 2250 cc column filled with 3 Å molecular sieves (8 - 12 mesh; Aldrich Chemical Company), then two 500 cc columns in series filled with 5 Å molecular sieves (8 - 12 mesh; Aldrich Chemical Company), then a 500 cc column filled with Selexsorb CD (BASF), and finally a 500 cc column filled with Selexsorb COS (BASF), the above - mentioned polymerization - grade propylene was further purified by passing it through these columns. The activation of the pre - catalyst was by either dimethylanilinium tetrakis(pentafluorophenyl)borate (Boulder Scientific or Albemarle Corp; Act ID = A), or (hydrogenated tallow alkyl)methylammonium tetrakis(pentafluorophenyl)borate (Boulder Scientific; Act ID = B) supplied as a 10 mass% solution in methylcyclohexane. The activator was typically used as a 0.25 mmol / L solution in toluene or isohexane. Tri - n - octylaluminum (TnOAl or TNOA, solvent - free, AkzoNobel) was also used as a scavenger before introducing the activator and the pre - catalyst into the reactor. TNOA was typically used as a 5 mmol / L solution in toluene or isohexane.

[0186] Description and preparation of the reactor: The polymerization was carried out using an autoclave equipped with an external heater for temperature control, a glass insert (C 2 and C 2 / C 8 In the case of, the internal volume of the reactor = 23.5 mL, and in the case of the implementation of C 3 ; 22.5 mL), with a septum inlet for regulating the supply of nitrogen, ethylene, and propylene, and equipped with a disposable PEEK mechanical stirrer (800 RPM), under an inert atmosphere (N 2It was carried out in a dry box of ). The autoclave was prepared by purging with dry nitrogen at 110 °C or 115 °C for 5 hours and then at 25 °C for 5 hours.

[0187] Propylene polymerization (PP): The reactor was prepared as described above, then heated to 40 °C, and then purged with propylene gas at atmospheric pressure. Toluene or isohexane, liquid propylene (1.0 mL), and a scavenger (TNOA, 0.5 μmol) were added by syringe. Next, while stirring at 800 RPM, the reactor was brought to the process temperature (70 °C or 100 °C). The activator solution and then the pre-catalyst solution were injected into the reactor by syringe under the process conditions. The reactor temperature was monitored and typically maintained within + / - 1 °C. Polymerization was terminated by adding a compressed dry air gas mixture at approximately 50 psi for approximately 30 seconds to the autoclave. Polymerization was quenched based on a predetermined pressure drop (maximum quench value) or for a maximum of 30 minutes. The reactor was cooled and vented. After removing the solvent in vacuo, the polymer was isolated. The actual quench time was reported as the quench time (s). The reported yield included the total mass of the polymer and the residual catalyst. Catalyst activity was reported as the grams of polymer per mmol of transition metal compound per hour of reaction time (g / mmol·h). Examples of propylene homopolymerization are reported in Table 2.

[0188] Polymer Characterization Regarding the analytical test, a solution of the polymer sample was prepared by dissolving the polymer in 1,2,4-trichlorobenzene (TCB, 99+% purity, Sigma-Aldrich) containing 2,6-di-tert-butyl-4-methylphenol (BHT, 99%, manufactured by Aldrich) in a shaker oven at 165 °C for approximately 3 hours. The typical concentration of the polymer in the solution was between 0.1 and 0.9 mg / mL, including a BHT concentration of 1.25 mg of BHT per 1 mL of TCB. The sample was cooled to 135 °C for the test.

[0189] High temperature size exclusion chromatography was performed using an automated "high speed GPC" system as described in U.S. Patent Nos. 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 weights (weight average molecular weight (Mw), number average molecular weight (Mn) and z average molecular weight (Mz)), and sometimes also the molecular weight distribution (MWD = Mw / Mn), also referred to as the polydispersity index (PDI) of the polymer, were measured by gel permeation chromatography using a Symyx Technology GPC equipped with an evaporative light scattering detector (ELSD) and calibrated using polystyrene standards (Polymer Laboratories: polystyrene calibration kit S-M-10: Mp (peak Mw) between 5,000 and 3,390,000). Alternatively, the samples were measured by gel permeation chromatography using a Symyx Technology GPC equipped with a dual wavelength infrared detector and calibrated using polystyrene standards (Polymer Laboratories: polystyrene calibration kit S-M-10: Mp (peak Mw) between 580 and 3,039,000). Samples (250 μL of polymer solution in TCB injected into the system) were run at an eluent flow rate of 2.0 mL / min (sample temperature 135 °C, oven / column 165 °C) using three Polymer Laboratories: PLgel 10 μm Mixed-B 300 × 7.5 mm columns in series. Column spreading correction was not used. Numerical analysis was performed using Epoch® software available from Symyx Technologies, or Automation Studio software available from Freeslate. The molecular weights obtained are relative to linear polystyrene standards. Molecular weight data are reported under the headings of Mn, Mw, Mz and PDI as defined above in Table 2.

[0190] Differential scanning calorimetry (DSC) measurements were performed on a TA-Q100 instrument to determine the melting point of the polymer. The samples were pre-annealed at 220 °C for 15 minutes and then cooled overnight at room temperature. Next, the samples were heated to 220 °C at a rate of 100 °C / min and then cooled at a rate of 50 °C / min. The melting point was collected during the heating period. The results are reported below the heading Tm (°C) in Table 2. The polymerization results are collected in Table 2 below. "Example number (Ex#)" represents the number of the example. Example numbers starting with "C" are comparative examples. "Cat ID" identifies the pre-catalyst used in this experiment. The corresponding numbers (also referred to as pre-catalysts, catalysts, complexes or compounds) identifying the pre-catalysts are in the synthesis experiment section. T (°C) is the polymerization temperature typically maintained within a range of + / - 1 °C. "Yield" is the polymer yield and is not corrected for catalyst residues. "Quench time" is the actual time in seconds for which the polymerization was carried out. In the case of propylene homopolymerization, the quench value indicates the maximum set pressure drop (conversion) of propylene during polymerization (in the case of PP). Activity is reported as grams of polymer per mmol of catalyst per hour.

[0191] Standard polymerization conditions include 0.015 μmol of catalyst complex, 1.1 equivalents of activator, 0.5 μmol of TNOA scavenger, 1.0 mL of propylene, 4.1 mL of total solvent, and the quench value is either a pressure drop of 8 psi or a maximum reaction time of 30 minutes. Activator A is N,N-dimethylanilinium tetrakis(pentafluorophenyl)borate activator, and activator B is (hydrogenated tallow alkyl)methylammonium tetrakis(pentafluorophenyl)borate. When activator A is used, the pre-catalyst solution is present in either isohexane or toluene, and the activator solution is present in toluene. When activator B is used, both the pre-catalyst and activator solutions are present in isohexane. A small amount of methylcyclohexane is derived from activator B supplied by the manufacturer as a 10 wt% solution in methylcyclohexane.

The 1-liter autoclave reactor was equipped with a stirrer, a pressure control device, and a water-cooling / steam-heating element by a temperature control device. This reactor was operated under liquid filling conditions at a reactor pressure above the bubble point pressure of the reactant mixture, maintaining the reactants in the liquid phase. Isohexane and propylene were pumped into the reactor by a Pulsa feed pump. The total liquid flow rate was controlled using a Coriolis mass flow controller (Quantim series made by Brooks). Ethylene was flowed as a gas under its own pressure by a Brooks flow controller. The feeds of ethylene and propylene were combined into one stream and then mixed with a stream of pre-cooled isohexane cooled to at least 0 °C. Next, this mixture was fed to the reactor from a single line. A solution of tri(n-octyl)aluminum was added to the above combined solvent and monomer stream immediately before they entered the reactor. The catalyst solution was fed to the reactor from an individual line using an ISCO syringe pump. Isohexane (used as a solvent) and monomers (e.g., propylene and ethylene) were purified over beds of alumina and molecular sieves. Toluene and isohexane used to prepare the catalyst solution were purified by the same technique.

[0193] The polymer produced in the reactor exited through a backpressure control valve that reduced the pressure to atmospheric pressure. As a result, the unconverted monomers in the solution were vigorously flowed into the vapor phase exhausted from the top of the vapor-liquid separator. To recover the polymer, the liquid phase mainly containing the polymer and the solvent was collected. The collected sample was first air-dried in a hood to evaporate most of the solvent, and then dried in a vacuum oven at a temperature of about 90 °C for about 12 hours. The sample dried in the vacuum oven was weighed to obtain the yield. All reactions were carried out at a pressure of about 2.4 MPa / g unless otherwise specified.

[0194] The conditions of the detailed polymerization method and the physical properties of the produced polymer are listed in Table C 1 below. N,N-Dimethylanilinium tetrakis(pentafluorophenyl)borate was used as the activator for all polymerizations. The catalyst solution was prepared by combining the catalyst with the activator in toluene. Examples G01 - G06 are propylene-ethylene copolymers made from catalyst 6. Examples G07 - G11 are propylene-ethylene copolymers made from catalyst 15. Examples G12 - G13 are propylene-ethylene copolymers made from catalyst 14.

[0195] The ethylene content was determined using FTIR in accordance with ASTM D3900.

[0196] The peak melting point Tm (also referred to as the melting point), the peak crystallization temperature Tc (also referred to as the crystallization temperature), the glass transition temperature (Tg), and the heat of fusion (ΔHf or Hf) were determined using differential scanning calorimetry (DSC) manufactured by TA Instruments (model Q200) in accordance with the procedure of ASTM D3418-03.

[0197] MFR is the melt flow rate (g / 10 min) measured at a temperature of 230 °C and a mass of 2.16 kg in accordance with ASTM D1238. HL MFR is the melt flow rate (g / 10 min) measured at a temperature of 230 °C and a mass of 21.6 kg in accordance with ASTM D1238.
