[0001] Cross - Reference to Related Applications This application claims priority to U.S. Provisional Patent Application No. 62 / 840,88 7, filed on April 30, 2019, the entire disclosure of which is incorporated herein by reference.
[0002] Embodiments of the present disclosure generally relate to alkene - functionalized activators, synthesis of activators, and their application to olefin polymerization processes.
Background Art
[0003] Olefin - based polymers, such as ethylene - based polymers and propylene - based polymers, are produced via various catalyst systems. The selection of such a catalyst system can be an important factor contributing to the characteristics and properties of the olefin - based polymer. Catalyst systems for producing polyethylene - based polymers can include chromium - based catalyst systems, Ziegler - Natta catalyst systems, or molecular (either metallocene or non - metallocene) catalyst systems. Activators are typically used in combination with metal precatalysts to form activated catalyst ion pairs, which are then used in the polymerization of olefins. As part of the catalyst composition in α - olefin polymerization reactions, activators can have beneficial characteristics for the production of α - olefin polymers and the final polymer composition containing α - olefin polymers. Characteristics of activators that increase the production of α - olefin polymers include, but are not limited to, rapid activation of the precatalyst, high catalytic efficiency, high - temperature capability, consistent polymer composition, and selective deactivation.
[0004]
[0005] To generate catalytically active species for the coincidence, a molecular polymerization procatalyst as part of the catalyst system is activated, and this activation can be achieved by any number of means. Such One such method uses an activator or cocatalyst that is a Bronsted acid. For molecular polymerization pro catalysts, particularly those containing Group IV metal complexes, generally Bronsted salts containing weakly coordinating anions are utilized. A fully ionized Bronsted salt can move a proton to form a cationic derivative of such a Group IV metal complex.
[0006] For activators such as Bronsted salts, as the cation component, for example, cations capable of moving hydrogen ions such as ammonium, sulfonium, or phosphonium, or oxidative cations such as ferrocenium, silver(I), or lead(II) cations, or highly Lewis acidic cations such as carbonium or silylium can be mentioned.
Summary of the Invention
Problems to be Solved by the Invention
[0007] However, when the cation of the activator or cocatalyst activates the procatalyst, the activator may remain in the polymer composition. As a result, the cations and anions may affect the polymer composition. Since not all ions diffuse equally different ions have different effects on the polymer composition. Specifically, the size of the ions, the charge of the ions, the interaction of the ions with the surrounding medium, and the ions with available counterions The dissociation energy with respect to N will affect the ability of the ions to diffuse through the surrounding medium such as a solvent, gel, or polymeric material. It will affect the ability of the ions to diffuse through the surrounding medium such as a solvent, gel, or polymeric material.
[0008] Conventional olefin polymerization activators include weakly coordinating or non-coordinating anions. It has been shown that the weak coordination of the anion results in an increase in the catalytic efficiency of the cationic catalyst. However, the non-nucleophilic character of the non-coordinating anion also increases diffusion, so the activator anion remaining in the resulting polymer lowers the electrical resistance of the polymer, thereby increasing electrical losses and reducing the insulating ability of the resulting polymer. It will lower the electrical resistance of the polymer, thereby increasing electrical losses and reducing the insulating ability of the resulting polymer. It will lower the electrical resistance of the polymer, thereby increasing electrical losses and reducing the insulating ability of the resulting polymer.

DETAILED DESCRIPTION OF THE INVENTION
[0019] The term "polymer" refers to a polymer compound prepared by polymerizing α-olefins, regardless of whether they are of the same or different types. Thus, the general term "polymer" encompasses the term "homopolymer", which is commonly used to refer to a polymer prepared from only one type of monomer, and the term "copolymer", which refers to a polymer prepared from two or more different monomers. As used herein, the term "interpolymer" refers to a polymer prepared by polymerizing at least two different types of monomers. Thus, the general term "interpolymer" includes copolymers and polymers prepared from three or more different types of monomers, such as terpolymers. The term "polyethylene" or "ethylene-based polymer" shall mean a polymer containing units derived from ethylene monomer in an amount exceeding 50 mole percent (mol%). This includes polyethylene homopolymers or copolymers (meaning units derived from two or more comonomers). Common forms of polyethylene known in the art include low density polyethylene (LDPE), linear low density polyethylene (LLDPE), ultra low density polyethylene (ULDPE), very low density polyethylene (VLDPE), linear and
[0020] A single-site catalyst linear low-density polyethylene (m-LLDPE) that includes both a calling and a substantially linear low-density resin ), medium-density polyethylene (MDPE), and high-density polyethylene (HDPE).
[0021] The disclosed embodiments include a polymerization process. In one or more embodiments, the polymerization process is to polymerize at least one (C - C 2 - C 12 ) α-olefin monomer in the presence of at least one catalyst and at least one cocatalyst . The cocatalyst has an anion and a cation. The cation of the cocatalyst is inserted into the polymer chain of the polyolefin. The anion of the cocatalyst has a structure that includes a vinyl-terminated alkene, one boron atom or two or more boron atoms, and at least four halogen atoms. In some embodiments, the anion of the cocatalyst has two vinyl-terminated alkene groups. In some embodiments, the polymerization process includes two cocatalysts, and both cocatalysts have an anion with a structure that includes one vinyl-terminated alkene, one boron atom or two or more boron atoms, and at least four halogen atoms. The term "vinyl-terminated alkene" refers to the arrangement of a double bond on a hydrocarbon. A vinyl - terminated alkene is a terminal double bond, e.g., R
[0022] HC=CH , where R E is hydro 2 carbyl. E is hydro carbyl. Scheme 1: Examples of anions that are inserted into or covalently incorporated into the polymer chain of a polyolefin. [Chemical formula]
[0023] In Scheme 1, "A" is the anion of the cocatalyst, "P" is the polymer chain, " M" is the metal center of the catalyst, and "L" is the ligand of the catalyst. The depiction of Scheme 1 illustrates the means by which the anion of the cocatalyst is inserted or covalently incorporated into the polymer chain of the polyolefin. The vinyl-terminal alkene of the anion of the cocatalyst functions as an olefin and is polymerized into the polymer chain. Scheme 1 is illustrative and not intended to be limiting. For example, Scheme 1 depicts a catalyst that is a metal-ligand catalyst (L-M). However, any catalyst activated by an activator or cocatalyst may be suitable in the processes of the present disclosure.
[0024] The term "activator" refers to a compound that chemically reacts with a precatalyst to convert the precatalyst into a catalytically active catalyst. As used herein, the terms "cocatalyst" and "activator" are interchangeable terms. The term "precatalyst" refers to a compound that has catalytic activity when combined with an activator.
[0025] As described above, the residual activator anion in the resulting polymer reduces the electrical resistance of the polymer, thereby increasing electrical losses and thereby reducing the insulating ability of the resulting polymer. Without intending to be bound by theory, since the anion is incorporated into the polymer chain, the migration or diffusion of the anion of the cocatalyst is thought to decrease throughout the composition of the polyolefin. Thus, the anion of the cocatalyst A polyolefin produced from a process that includes incorporation into the polymer chain of the co-catalyst has electrical properties that are better than expected, such as a lower dielectric tangent, when compared to a comparative polymer produced under similar conditions, except that the co-catalyst was not incorporated into the polymer chain of the comparative polymer. has electrical properties that are better than expected, such as a lower dielectric tangent, when compared to a comparative polymer produced under similar conditions, except that the co-catalyst
[0026] In an embodiment, the polymer process includes polymerizing one or more (C -C 2 -C 12 )α-olefin monomers in the presence of at least one catalyst and at least one co-catalyst to produce a polyolefin. The anion of the co-catalyst is then inserted into the polymer chain of the polyolefin. has electrical properties that are better than expected, such as a lower dielectric tangent, when compared to a comparative polymer produced under similar conditions, except that the co-catalyst

The phrase "under the same polymerization conditions" means that the polymerization process occurs under the same conditions in the same type of reactor. The "same type of reactor" does not limit the polymerization process carried out in the reactor that produced the polyolefins of the present disclosure, nor does it limit the polymerization process to the same location. For example, when a polyolefin produced by a cocatalyst having an anion of formula (I) is polymerized in a batch reactor, the corresponding polyolefin composition produced by a cocatalyst having an anion of formula (Ia) is also polymerized in a batch reactor.

In some embodiments, the polymerization process uses at least a small amount to produce a polyolefin. For example, when a polyolefin produced by a cocatalyst having an anion of formula (I) is polymerized in a batch reactor, the corresponding polyolefin composition produced by a cocatalyst having an anion of formula (Ia) is also polymerized in a batch reactor. Furthermore, "the same conditions" means that each reactor is filled with the same molar amount of catalyst, cocatalyst, comonomer (if a comonomer is present), hydrogen (if hydrogen is present), and ethylene pressure (if ethylene is present), filled with the same volume amount of solvent, and each reactor is heated to the same temperature at the same rate of temperature increase.

Chemical formula
[0044] Electrical properties of the polymer The insulating medium should be as efficient as possible. Electrical losses reduce the efficiency with which the medium insulates in the presence of an electric field. Since resistance is inversely correlated with power or electrical loss, the resistance should be as high as possible in both alternating current (AC) and direct current (DC) systems. In a DC system (e.g., a photovoltaic encapsulant), the energy loss appears as leakage current from the encapsulated device to the external environment. This current (I) is correlated with the voltage (V) and is inversely correlated with the resistance (R) of the insulating medium via the equation I = V × R. Therefore, the higher the resistance, the lower the current and leakage current. In an AC system (e.g., a cable insulator), the loss appears as the absorption of energy by the medium in the presence of an electric field. This loss, measured as power (P), is determined by the equation P = V × ω × C × ε′ × tan δ, where ω is the angular frequency, ε’ is the relative permittivity, C is the capacitance, and tan δ is the dielectric tangent, and tan δ = (C × R
[0045] × ω), resulting in the equation P = V × ε′ × R. Since resistance is inversely correlated with power loss, the higher the resistance, the lower the power loss. Equation I = V × R -1 One physical effect that reduces the resistance of the medium is ion diffusion caused by the electric field. In a system where ion diffusion dominates the electrical response, the resistance is given by the equation R ∝ 6 × π × ε′ × ε × η × r × C
[0046] × q × ω), resulting in the equation P = V 2 × ω × C × ε′ × tan δ, where ω is the angular frequency, ε’ is the relative permittivity, C is the capacitance, and tan δ is the dielectric tangent, and tan δ = (C × R × ω), resulting in the equation P = V × ε′ × R -1 Equation P = V 2 × ε′ × R -1 Since resistance is inversely correlated with power loss, the higher the resistance, the lower the power loss. One physical effect that reduces the resistance of the medium is ion diffusion caused by the electric field. In a system where ion diffusion dominates the electrical response, the resistance is given by the equation R ∝ 6 × π × ε′ × ε
[0047] × η × r × C × q 0 × η × r × C -1 × q -2×N -1 For the diffusing ion via 0 is the dielectric constant of a vacuum Rate(8.854×10 -12 F m -1 ), η is the dynamic viscosity of the medium, and r is the where q is the hydrodynamic radius of the ion, q is the charge of the ion, and N is the concentration of the ion. Increasing resistance reduces energy loss, and decreasing ion concentration increases resistance, so Reducing the concentration of ions diffusing through the body reduces energy loss.
[0048] In addition to size and charge, the interaction of the ion with the surrounding medium and with the target molecule are also important. The dissociation energy with available counterions affects the ability of an ion to diffuse through a given medium. This will have an effect on the activator because not all ions diffuse equally. The ability of the ions to diffuse is an important characteristic. has reduced diffusion of the anion and countercation of the cocatalyst of the present disclosure of formula (I) The resulting polymers of the cocatalysts of the present disclosure have reduced energy loss, which is a good It is believed to provide electrical properties.
[0049] In one or more embodiments, the polyolefin produced by any of the processes of the present disclosure. The insulator has a dielectric tangent of less than 0.10 at a frequency of 100 Hz and a temperature of 130°C. In various embodiments, the polyolefin has a thermal expansion coefficient of 1. In another embodiment, the polyolefin has a dielectric loss tangent of less than 1.00 at a frequency of 1.0 Hz. In some embodiments, the polyimide has a dielectric constant of less than 10 at a temperature of 130° C. Olefins have a dielectric loss tangent of less than 100 at a frequency of 0.10 Hz and a temperature of 130°C. Do.
[0050] The dielectric tangent relates to the electrical properties of the resin. Reduction of the dielectric tangent produces a material (e.g., cable insulator or electronic encapsulant) that can be used as a dielectric medium. When the dielectric tangent is mainly caused by ions in the resin, removal or immobilization of these ions can reduce the dielectric tangent and improve the electrical properties of the resin. On a small scale, the polymer produced with the cocatalyst having the anion of formula (I) exhibits a dielectric tangent that is one-tenth that of our standard polymer produced with cocatalyst C1. Without being bound by theory, it is believed that the polyolefin produced with the cocatalyst having the anion of formula (I) will have a dielectric tangent that is one-tenth that of cocatalyst C1 when the polyolefin is produced on an industrial scale. The dielectric tangent of a standard poly(ethylene-octene) copolymer is about 1.0. Accordingly, we predict that the polyolefin polymer produced with the cocatalyst having the anion of formula (I) will exhibit a dielectric tangent of 0.1 or less at 60 Hertz (Hz). When the dielectric tangent is mainly caused by ions in the resin, removal or immobilization of these ions can reduce the dielectric tangent and improve the electrical properties of the resin.

[0082] Add experiments on dielectric loss tangent Batch reactor procedure The experiments in the batch reactor were carried out in a 1-gallon continuous stirred tank reactor. After filling the reactor with Isopar- E hydrocarbon solvent, hydrogen, and an appropriate amount of octene comonomer, it was heated to a specific temperature and pressurized to 450 psi with ethylene. When the reactor was under pressure, polymerization was initiated by adding an activated catalyst solution containing a procatalyst, a cocatalyst of the present disclosure, a solvent, and a triethylaluminum scavenger. The polymerization was allowed to proceed for 10 minutes while maintaining the temperature and pressure of the reactor. After the reaction was completed, the polymer was collected and dried in a vacuum oven overnight before analysis.
[0083] General procedure for 1-octene polymerization: In a nitrogen-filled glove box, neat 1-octene (11 mL) was placed with a stir bar It was added to a 40 mL vial equipped with a polyurethane insulated block placed on a magnetic stirring plate. The vial was placed on the block. A solution of the precatalyst and activator (1.2 - 1.25 equivalents relative to the precatalyst) in toluene was added continuously. The vial was capped and the reactants were stirred for the specified time (3 hours for precatalyst 2 and precatalyst 3, 6 days for precatalyst 3). All volatile substances were removed under reduced pressure to produce a polyoctene resin, which was then characterized by GPC and submitted for electrical testing.
[0084] General procedure for ethylene / 1 - octene copolymerization: Ethylene / 1 - octene screening is carried out in a high - throughput parallel polymerization reactor (PPR) system. The PPR system consists of a series of 48 single - cell (6×8 matrix) reactors in an inert atmosphere glove box. Each cell is equipped with a glass insert having an internal working liquid volume of about 5 mL. Each cell has independent pressure control and is continuously stirred at 800 rpm using a PEEK stirring paddle. The catalyst, ligand, and metal precursor solutions are prepared in toluene. All liquids (i.e., solvent, 1 - octene, scavenger, activator, and precatalyst solution) are added via a robotic syringe. Gaseous reagents (i.e., ethylene) are added via a gas injection port. Prior to each run, the reactor is heated to 80 °C, purged, and aerated with ethylene.
[0085] To produce a sufficient amount of polymer for electrical testing, 24 replicates (half of the 48 reactors) are carried out for each precatalyst and activator combination. The polymers obtained from the 24 replicates are then combined.
[0086] The reactor was heated to 100 °C and then pressurized with ethylene to 25.3 psig, and a portion of Isop ar-E was added. A toluene solution of the reagents was then added to each reactor in the following order: (1 ) 1-octene (1.10 mL for procatalyst 3 and 2.26 mL for procatalyst 2), (2) the scavenging agent triethylaluminum (TEA) (1 μmol), (3) the activator (comparative cocatalyst C1 -C3 or cocatalyst 1-7 (i.e., alkenyl-substituted carborane) (added in an amount of 1.2 molar equivalents relative to the procatalyst), (4) the procatalyst (20 nmol for procatalyst 3 and 80 nmol for procatalyst 2). After the addition of each liquid, a small amount of Isopar-E was added, and after the final addition, the total reaction volume was brought to 5
[0087] mL. When adding the catalyst, the pressure of each cell was monitored with PPR software . The desired pressure (within approximately 2 - 6 psig) was maintained by opening the valve at the setpoint minus 2 psi and closing the valve when the pressure reached 2 psi higher, by the make-up addition of ethylene gas . Any pressure drop was cumulatively recorded as the "uptake" or "conversion" of ethylene, either over the course of the run or earlier, whichever occurred first, until the uptake or conversion demand value was reached. Each reaction was then quenched by the addition of 10% carbon monoxide in argon at a pressure 40 - 50 psi higher than the reactor pressure for 1 - 4 minutes. To prevent the formation of excess polymer in any given cell, the reaction was quenched when a predetermined uptake level (50 psig) was reached. After all the reactors were quenched , they were then vented and the glass tube inserts containing the samples were removed. When they were removed, It was cooled to 70 °C. Polymers containing solutions from 24 reactors containing the same procatalyst and activator solution were combined and stored out of the draft for several days. The resulting resin containing the solution was then dried in a vacuum oven at 80 °C for 3 hours and 140 °C for 4 hours, in one continuous cycle, weighed to determine the polymer yield, and submitted for GPC analysis performed.

[0089] The reaction mixture for the mass spectrometry result of Example 4 was prepared at 5 mg / mL in non-inhibiting tetrahydrofuran (THF ). Each sample was subjected to negative ion mode flow injection mass spectrometry on an Agilent 1290 Infinity II ultra-high performance liquid chromatograph (UHPLC) and an Agilent 6538 ultra high resolution accurate mass quadrupole time-of-flight mass spectrometer (QTOF MS). 20 microliters of the analyte solution was injected into the UHPLC in flow -injection mode, and the mobile phase was 66.7% non-inhibiting THF and 33.3% methanol with 1 g / L ammonium formate (flow rate 0.3 mL / min). The eluate from the liquid chromatograph was introduced into the MS and ionized in negative ion mode by electrospray ionization . A combination of MS and MS / MS data was collected. The mass spectrum was externally calibrated to generate accurate mass information within + / - 10 mDa. After external calibration, accurate mass prediction software (Agilent Using (t Masshunter), the empirical formulas of MS and fragment ions were generated. Both the predicted empirical formulas and dissociation behaviors of each parent ion were utilized to provide the proposed structure. has been provided.
[0090] Unless otherwise specified, all operations were carried out under an Ar atmosphere using standard Schlenk techniques of the glovebox method. Klein was used. Toluene, pentane, C 6 D 6 and T HF was dried with NaK / Ph 2 CO / 18-crown-6, distilled or transferred under vacuum, and stored over molecular sieves in an Ar-filled glovebox. NMR spectra were recorded on a Varian Inova 500 spectrometer ( 1H NMR, 499.703 MHz, 1 13C NMR 13 125.580 MHz), Varian Inova 400 ( 11B NMR, 128 11 .191 MHz) spectrometer, Bruker 400 ( 13C 100, 13 11B 102 MH 11 z).

[0110] Example 4-1-Octene Polymerization Polyoctene was produced by mixing procatalyst 1 and olefin-substituted cocatalyst 1 in 1-octene. The average molecular weight of the final polyoctene product was determined by size exclusion chromatograph. The Mn was previously determined to be 1449 amu by olefin incorporation. In addition, the carborane activator contains 11 boron atoms (black dots in cocatalyst 1), Contains 11 chloride atoms and a fixed negative charge. Polyolefin (polyoctene) To confirm the incorporation of the anion in the reaction mixture and Additional controls were analyzed.
[0111] The polyoctene produced from the catalyst and the olefin-substituted carborane activator was The polyoctyltransferase of carborane was analyzed by active-mode flow injection mass spectrometry. In Figure 1, the distribution of singly charged ions at m / z 112 m / z 786.056 (i.e., O in the mass spectrum) 2 The accurate mass analysis of the compound C, denoted as C, was further investigated and found to have a mass error of 5 mDa. 2 0 H 37 B 11 Cl 11 This coincided with the empirical formula (Figure 2).20 H 37 B 11 Cl 1 1 The theoretical isotope modeling of 1 was consistent with the isotope profiles and relative abundances of the experimental data (Figure 3). Based on the experimental formula and periodicity of 112 amu, m / z 786.05 6 was consistent with the carborane activator polymerized with two octene monomers. The subsequent fragmentation of m / z 7 86.056 was carried out to help confirm the covalent incorporation of the carborane activator. The initial fragmentation conditions required 70 V of energy to generate fragmentation, but there was not enough energy to generate fragment ions (i.e., 35 V). During fragmentation, homolytic cleavage of the carbon-carbon bond in the boron cage olefin linker was observed in the spectrum of Figure 4. This observation, along with substantially higher fragmentation conditions than normal, indicates that the intact olefin-containing carborane starting reagent was not observed as fragment ions, so the carborane activator was covalently incorporated into the polyoctene. In addition to this peak, other ion signals in the mass spectrum were investigated. Overall, the m / z 786.056 peak functioned as a representative example of other ion signals . Accurate mass spectrometry, isotope modeling, and fragmentation of additional ion signals (m / z 890 - 3100) were consistent with increased polymerization of octene, where a maximum of 22 polyoctene chains incorporated with the carborane activator were observed. For comparison purposes, catalyst P1 and a hydrogen-substituted (olefin-free) carborane activator comparison C3 ([B C l were used. Since the intact olefin-containing carborane starting reagent was not observed as fragment ions, it indicates that the carborane activator was covalently incorporated into the polyoctene . In addition to this peak, other ion signals in the mass spectrum were investigated. Overall, the m / z 786.056 peak functioned as a representative example of other ion signals .

[0112] Example 5 - Polymerization Results To obtain the data recorded in Table 1, the polymerization was carried out according to the procedure described in the polymerization section of 1 - octene. To obtain the data presented in Table 2, the polymerization reaction was carried out according to the procedure in the general procedure section of ethylene / 1 - octene copolymerization described above and the activator efficiency and the polymer characteristics obtained were evaluated for cocatalysts 1 - 7. Each anion of cocatalysts 1 - 7 has an anion according to formula (I), and the catalyst (Catalyst 1) was presumed to be formed from a procatalyst with a bis((phenylphenoxy) structure according to formula (X) (Procatalyst 3, herein referred to as "P3" ) and two other catalysts previously described in the present disclosure (Procatalyst 1, herein referred to as " P1", and Procatalyst 2, herein referred to as " P2"). ) and two other catalysts previously described in the present disclosure (Procatalyst 1, herein referred to as " P1", and Procatalyst 2, herein referred to as "

[0113] Each of cocatalysts 1 - 7 and Comparative cocatalysts C1, Comparative cocatalyst C2, Comparative cocatalyst C3, and Comparative cocatalyst C4 (herein referred to as "Comparative C1", "Comparative C2", "Comparative C3", and " Comparative C4") was mixed with one of Procatalyst 1, Procatalyst 2, or Procatalyst 3 Thus, 16 catalyst systems were formed. Comparative C1 was tetrakis(pentafluorophenyl)borate anion, and as the counter cation + NH(Me)(C 18 H 37 ) 2 and had a compound which was successfully used in industrial-scale olefin polymerization reactions .
Table 1
[0114] The density of the polymers produced by cocatalysts 1-7 was measured at 0.86 ± 0.05 g / cm 3 .
[0115] To avoid cross-contamination, 1-octene was polymerized in a glass vial. This procedure was described in the previous paragraph. The polyoctene produced was measured by broadband dielectric spectroscopy . Figures 6-9 are graphs of broadband dielectric spectroscopy. Each polymer produced from the catalyst system showed a slope of -1 at low frequencies, indicating that ionic diffusion is the main factor in the dielectric tangent . The graph in Figure 6 shows that Comparative C1 and Comparative C2 showed similar dielectric tangents, while the polymers produced from the catalyst systems containing cocatalysts 1 , 2, 3, and 4 showed a dielectric tangent that was one-tenth that of the comparative cocatalyst . The difference between Comparative C2 and cocatalysts 1, 2, 3, and 4 is that cocatalysts 1 , 2, 3, and 4 contain vinyl-terminated alkenes at the R 1 position. Comparative C2 and cocatalysts 1, 2, 3, and 4 are of similar size and thus would be expected to have similar diffusion rates . Thus, the ten-fold decrease in the comparative cocatalyst is due to cocatalysts 1 Each of 2, 3, and 4 is incorporated into the polyoctene backbone and cannot diffuse freely, and thus has a lower dielectric tangent when compared to comparative C2 which is not incorporated. This is shown by having a lower dielectric tangent when compared to comparative C2 which is not incorporated. This is shown by having a lower dielectric tangent when compared to comparative C2 which is not incorporated.
[0116] The dielectric tangent test was performed with a Novocontrol Alpha A dielectric analyzer and a custom sample cell. The samples were measured at room temperature from 0.01 Hz to 1 MHz, 1.5 VAC. Briefly, the sample cell was first measured with dry air to obtain background measurements. Next, the highly viscous polyoctene sample was placed on one of the electrodes with a clean spatula and the test cell was closed. Excess polyoctene was pushed out from the electrode into the adjacent channel as designed. The dielectric tangent of the complete test cell was then measured. The test cell was then cleaned with toluene and completely dried before the next measurement. Five different polyoctene samples were provided, three made with cocatalyst comparative C1, one with carborane, and one made with allyl-substituted carborane. To confirm reproducibility, each sample was measured at least twice.
Table 2
[0117] The equivalence of the cocatalyst to the procatalyst was 1.2.
[0118] The dielectric tangents of the ethylene-octene copolymers recorded in Table 2 were measured, and the spectra obtained are shown in FIGS. 8 and 9. FIG. 8 shows the spectra of two comparative examples of ethylene-octene copolymers produced from procatalyst P3 and comparative cocatalyst C1 or C3, and ethylene-octene copolymers produced from procatalyst P3 and cocatalyst 7. The dielectric tangents of the ethylene-octene copolymers recorded in Table 2 were measured, and the spectra obtained are shown in FIGS. 8 and 9. FIG. 8 shows the spectra of two comparative examples of ethylene-octene copolymers produced from procatalyst P3 and comparative cocatalyst C1 or C3, and ethylene-octene copolymers produced from procatalyst P3 and cocatalyst 7. from procatalyst P3 and cocatalyst 7. from procatalyst P3 and cocatalyst 7. Therefore, the dielectric tangent of the resulting polymer is one-tenth of the dielectric tangent.
[0119] Figure 9 shows the spectra of two comparative examples of an ethylene-octene copolymer produced from procatalyst P2 and comparative cocatalyst C1 or C3, and an ethylene-octene copolymer produced from procatalyst P2 and cocatalyst 7. The dielectric tangent of the polymer produced by cocatalyst 7 and procatalyst P2 is, like the dielectric tangent of the polymer shown in Figure 8 and produced by cocatalyst 7 and procatalyst P3, one-tenth of the dielectric tangent of the polymer produced by procatalyst P3 and comparative cocatalyst C1, and of the polymer produced by procatalyst P3 and comparative cocatalyst C3.
