Definitions

  • the present disclosure provides borate activators, a process for producing borate activators in aliphatic and alicyclic solvents, catalyst systems comprising such activators, and processes for polymerizing olefins using such activators.
  • non-coordinating anion type activators comprising a benzimidazolium moiety.
  • Polyolefins are widely used commercially because of their robust physical properties. Polyolefins are typically prepared with a catalyst that polymerizes olefin monomers. Therefore, there is interest in finding new catalysts and catalyst systems that provide polymers having improved properties.
  • Catalysts for olefin polymerization are often based on metallocenes as catalyst precursors, which are activated either with an alumoxane or an activator containing a non coordinating anion.
  • a non-coordinating anion such as tetrakis(pentafluorophenyl)borate, is capable of stabilizing the resulting metal cation of the catalyst.
  • activators are fully ionized and the corresponding anion is highly non-coordinating, such activators can be effective as olefin polymerization catalyst activators. However, because they are ionic salts, such activators are insoluble in aliphatic hydrocarbons and only sparingly soluble in aromatic hydrocarbons.
  • activators often exist in the form of an oily, intractable material which is not readily handled and metered or precisely incorporated into the reaction mixture.
  • polymer products, such as isotactic polypropylene, formed using such activators can have lower molecular weights (e.g., Mw less than about 100,000) and a high melt temperature (Tm) (e.g., Tm greater than about 110°C).

  • A-methyl-4-nonadecyl- N-octadecylanilinium tetrakis(heptafluoronaphthalen-2-yl)borate (NOMAH-BF28) and N- methyl-4-nonadecyl-N-octadecylanilinium tetrakis(pentafluorophenyl)borate (NOMAH- BF20) were prepared from iV-methy 1-4-nonadecyl-N-octadecy land ini um chloride and their corresponding borates by procedures similar to those described below. All other reagents and solvents were purchased from Sigma-Aldrich. NMR spectra were recorded on a Bruker 500 or 400 NMR with chemical shifts referenced to residual solvent peaks (CDCb: 7.27 ppm for 3 ⁇ 4, 77.23 ppm for 13 C).
  • MBH-BF28 1-Methylbenzimidazole (2.00 g, 15.1 mmol) was dissolved in 100 mL of hexane. A 2 M ethereal solution of HC1 (7.6 mL, 15 mmol) was added slowly, which caused a white precipitate to form. After stirring for 16 hours, the white solid was collected, washed with fresh hexane, and dried under vacuum to give the benzimidazolium salt in 88% yield. The 1 -methylbenzimidazolium HC1 salt (500 mg, 2.97 mmol) was dissolved in 100 mL of dichloromethane and combined with Na-BF28 (3.10 g, 2.97 mmol).
  • l-octadecyl-lH-benzo[d]imidazole Benzimidazole (5.0 g, 42 mmol) was dissolved in 250 mL of THF and cooled to 0°C. Sodium hydride (1.28 g, 51 mmol) was added slowly and the reaction allowed to warm to ambient temperature over 45 min. The reaction was cooled back to 0°C and bromooctadecane (14.11 g, 42 mmol) was added. The solution was heated at 70°C for 2 hours, then allowed to stir at ambient overnight.
  • the 1-octadecylbenzimidazolium HC1 salt (500 mg, 1.23 mmol) was dissolved in 100 mL of cyclohexane and combined withNa-BF28 (1.29 g, 1.23 mmol). The mixture was heated at reflux for 1.5 hours, then cooled to ambient and filtered. The filtrate was concentrated to give the product as a white solid in 15% yield.
  • 1-Hexene polymerization A series of 1 -hexene polymerizations were performed in 20 mL scintillation vials. In these examples, the metallocene rac-dimethylsilyl- bis(indenyl)hafhium dimethyl (MCN-1) was used with various ammonium borate activators. These data and run conditions are shown in Table 3.
  • the general polymerization conditions utilized 2 mis 1 -hexene, 500 nanomoles MCN-1 catalyst, 550 nanomoles of the indicated activator, and 10 micromoles tri(n- octyljaluminum as a scavenger in a total volume of 10 ml isohexane.
  • Solubility study of the activators A saturated solution of the activator was prepared by slowly adding the solvent to a pre-weighed amount of the activator. The final volume was determined as the minimum amount of solvent required to convert the heterogenous mixture into a homogeneous solution. The concentration of the saturated solution is presented in millimoles of activator per liter of solution (mM). Alternatively, a mixture of the activator was prepared by adding the solvent to an excess amount of activator. The resulting heterogeneous mixture was separated from the undissolved solids by decanting the supemate mixture into a tared vial. Solvent was then added dropwise until the mixture became a homogeneous solution. The mass of the final solution was measured and then the solvent was evaporated to dryness to obtain the mass of the activator. The concentration of the saturated solution is presented in millimoles of activator per liter of solution (mM).
  • Tri-n- octylaluminum (TNOAL, neat, AkzoNobel) was typically used as a scavenger. Concentration of the TNOAL solution in toluene ranged from 0.5 to 2.0 mmol/L.
  • Ethylene-Octene Copolymerization (EO). A pre-weighed glass vial insert, and disposable stirring paddle were fitted to each reaction vessel of the reactor, which contains 48 individual reaction vessels. The reactor was then closed and purged with ethylene. Each vessel was charged with enough solvent (typically isohexane) to bring the total reaction volume, including the subsequent additions, to the desired volume, typically 5 mL. 1-octene, if required, was injected into the reaction vessel and the reactor was heated to the set temperature and pressurized to the predetermined pressure of ethylene, while stirring at 800 rpm. The aluminum compound (such as tri-n-octylaluminum) in toluene was then injected as scavenger followed by addition of the activator solution (typically 1.0-1.2 molar equivalents).
  • solvent typically isohexane
  • the catalyst (and activator solutions for Run A) were all prepared in toluene.
  • the catalyst solution typically 0.020-0.080 pmol of metal complex
  • the catalyst solution was injected into the reaction vessel and the polymerization was allowed to proceed until a pre-determined amount of ethylene (quench value typically 20 psi) had been used up by the reaction.
  • the reaction may be allowed to proceed for a set amount of time (maximum reaction time typically 30 minutes).
  • Ethylene was added continuously (through the use of computer controlled solenoid valves) to the autoclaves during polymerization to maintain reactor gauge pressure (P setpt, +/-2 psig) and the reactor temperature (T) was monitored and typically maintained within +/-1°C.
  • the reaction was quenched by pressurizing the vessel with compressed air. After the reactor was vented and cooled, the glass vial insert containing the polymer product and solvent was removed from the pressure cell and the inert atmosphere glove box, and the volatile components were removed using a Genevac HT-12 centrifuge and Genevac VC3000D vacuum evaporator operating at elevated temperature and reduced pressure. The vial was then weighed to determine the yield of the polymer product. The resultant polymer was analyzed by Rapid GPC (see below) to determine the molecular weight, by FT-IR (see below) to determine percent octene incorporation, and by DSC (see below) to determine melting point (T m ).
  • Polymer sample solutions were prepared by dissolving polymer in 1, 2, 4-tri chlorobenzene (TCB, 99+% purity from Sigma- Aldrich) containing 2,6-di- tert-butyl-4-methylphenol (BHT, 99% from Aldrich) at 165°C in a shaker oven for approximately 3 hours.
  • the typical concentration of polymer in solution was between 0.1 to 0.9 mg/mL with a BHT concentration of 1.25 mg BHT/mL of TCB.
  • the system was operated at an eluent flow rate of 2.0 mL/minutes and an oven temperature of 165°C. 1 ,2, 4-tri chlorobenzene was used as the eluent.
  • the polymer samples were dissolved in 1,2, 4-tri chlorobenzene at a concentration of 0.28 mg/mL and 400 uL of a polymer solution was injected into the system.
  • the concentration of the polymer in the eluent was monitored using an evaporative light scattering detector.
  • the molecular weights presented are relative to linear polystyrene standards and are uncorrected, unless indicated otherwise.
  • DSC Differential Scanning Calorimetry
  • the weight percent of ethylene incorporated in polymers was determined by rapid FT-IR spectroscopy on a Bruker Equinox 55+ IR in reflection mode. Samples were prepared in a thin film format by evaporative deposition techniques. FT-IR methods were calibrated using a set of samples with a range of known wt% ethylene content. For ethylene- 1-octene copolymers, the wt% octene in the copolymer was determined via measurement of the methyl deformation band at -1375 cm 1 . The peak height of this band was normalized by the combination and overtone band at -4321 cm 1 , which corrects for path length differences.
  • Ethylene-octene copolymerization (EO). A series of ethylene-octene polymerizations were performed in the parallel pressure reactor according to the procedure described above. In these examples, rac-dimethylsilyl-bis(indenyl)hafnium dimethyl (MCN- 1) was used as the catalyst along with ammonium borate activators.
  • Catalyst and activator were used in a 1 : 1.1 ratio. Each reaction was performed at a specified temperature range between 50 and 120°C, typically 80°C, while applying about 75 psig of ethylene (monomer) gas. Each reaction was allowed to run for about 20 minutes (-1,200 seconds) or until approximately 20 psig of ethylene gas uptake was observed, at which point the reactions were quenched with air (-300 psig). When sufficient polymer yield was attained (e.g, at least -10 mg), the polyethylene product was analyzed by Rapid GPC, described below.
  • RUN B Ethylene homopolymerization (PE).
  • PE Ethylene homopolymerization

  • the percent incorporation of 1-octene was also increased from a range of 48-50 % from the polymer produced by NOMAH-BF28 to 61-65% produced by MBH-BF28. This resulted in a decrease in the peak melt temperature of the polymer from a range of 30-36°C to 26-31°C. Polymers produced by the activator/catalysts system with OdBH-BF28 showed similar trends, with increased molecular weight range of 770-800 kg/mol, 59-64% octene, and 26-27°C melting point.
