NOVEL ALUMINUM ALKYL WITH C₅ CYCLIC AND PENDENT OLEFIN POLYMERIZATION CATALYST

INVENTORS; Matthew W. Holtcamp, Gregory S. Day

FIELD OF THE INVENTION

[0001] This invention claims priority to and the benefit of USSN 61/896,965 filed October 29, 2013 and the EP Application 14153047.7, filed January 29, 2014.

[0002] The present invention relates to organoaluminum compounds, to organoaluminum activator systems, preferably supported, to polymerization catalyst systems containing these activator systems and to polymerization processes utilizing the same. In particular, this invention relates to catalyst systems comprising an ion-exchange layered silicate, an organoaluminum compound and a metallocene.

BACKGROUND OF THE INVENTION

[0003] Metallocene olefin polymerization catalyst systems typically use an activator (also called a co-catalyst) to generate the active catalytic species. In general, there are two catalyst activator families: partially hydro lyzed aluminum alkyl complexes and non-coordinating anions (NCA's). Some of the most commonly employed activators used today are the partially hydrolyzed aluminum alkyls, more specifically, alumoxanes, such as methylalumoxane (MAO). In general, metallocene olefin polymerization systems that utilize NCA-type activators are more active than their MAO counterparts, but are also quite costly and much more sensitive to poisons which present a problem in catalyst synthesis, handling, storage and reactor operation. Alternatively, MAO-based systems are more robust than their NCA-type counterparts, but they suffer from the high cost of MAO production, the fact that MAO is typically used in large excess (relative to the amount of metallocene) and the limited shelf life of MAO.

[0004] In order to enhance polymer morphology, metallocene polymerization catalysts operated in industrial slurry and gas phase processes are typically immobilized on a carrier or a support, such as alumina or silica. Metallocenes are supported to enhance the morphology of the forming polymeric particles such that they achieve a shape and density that improves reactor operability and ease of handling. However, the supported versions of metallocene polymerization catalysts tend to have lower activity as compared to their homogeneous counterparts. In general, metallocene and single-site catalysts are immobilized on silica supports. [0005] Alternative supports for metallocene and single-site catalysts have been the subject of numerous ongoing research projects. In particular, metallocenes supported on clay or ion-exchanged layered compounds have generated interest. Olefin polymerization catalysts using clay, clay mineral or acid/salt-treated (or a combination of both) ion-exchange layered compounds, an organoaluminum compound and a metallocene as components have been reported (see EP 0 51 1,665A2; EP 0 511,665B1 ; and US 5,308,811). Likewise, US 5,928,982 and US 5,973,084 report olefin polymerization catalysts containing an acid or salt- treated (or a combination of both) ion exchange layered silicate, containing less than 1% by weight water, an organoaluminum compound and a metallocene. Furthermore, WO 01/42320A1 discloses combinations of clay or clay derivatives as a catalyst support, an activator comprising any Group 1-12 metal or Group 13 metalloid, other than organoaluminum compound, and a Group 3-13 metal complex. Also, US 6,531,552B2 and EP 1, 160,261A1 report an olefin polymerization catalyst of an ion-exchange layered compound having particular acid strength and acid site densities. US2003/0027950A1 reports an olefin polymerization catalyst utilizing ion-exchange layered silicates with a specific pore size distribution and having a carrier strength within a specific range.

[0006] Likewise, alternative activators for metallocenes and other single-site polymerization catalysts have been the subject of research efforts in recent years. For example, perfluorophenyl aluminum and borane complexes containing one anionic nitrogen- containing group may activate metallocenes. For example, R.E. Lapointe, G.R. Roof, K.A. Abboud, J. Klosin, J. Am. Chem. Soc. 2000, 122, pp. 9560-9561, and WO 01/23442A1 report the synthesis of (C₆F₅)3Al(imidazole)[Al(C₆F₅)3][HNR'R"]. In addition, G. Kehr, R. Frohlich, B Wibbeling, G. Erker, Chem. Eur. J. 2000, 6, No.2, pp. 258-266 report the synthesis of (N-Pyrrolyl)B(C6F₅)₂. Supported activators containing a Group 13 element and at least one halogenated, nitrogen-containing aromatic group ligand for polymerization catalysts have been reported (US 6, 147, 173 and US 6,211,105). J. Am. Chem. Soc, 1995, 117, 10771-10772 discloses the reaction of various monosubstituted alkenes containing hydrocarbon substituents as well as those containing heteroatom substituents with MesAl and a catalytic amount of a chiral zirconocene derivative provides, after oxidation with oxygen, 2- methyl-l-alkanols in generally high yields.

[0008] Given the high cost, low stability and reduced activity of MAO-based metallocene polymerization systems, there is a need in the art for new inexpensive, stable and supportable polymerization catalyst activator compounds.

SUMMARY OF THE INVENTION

[0009] This invention relates to supported activators comprising the product of the combination of an ion-exchange layered silicate, and an organoaluminum activator compound.

DEFINITIONS

[0013] For the purposes of this patent specification and the claims thereto, the term "activator" is used interchangeably with the term "co-catalyst", the term "catalyst" refers to a metal compound that when combined with an activator polymerizes olefins, and the term "catalyst system" refers to the combination of a catalyst and an activator with or without a support. The terms "support" or "carrier", for purposes of this patent specification, are used interchangeably and are any ion-exchange layered silicates.

[0014] As used herein, the new notation for the Periodic Table Groups is used as described in Chemical and Engineering News, 63(5), 27 (1985).

[0015] The term "substituted" means that a hydrogen group has been replaced with a hydrocarbyl group, a heteroatom, or a heteroatom containing group. For example, methyl cyclopentadiene (Cp) is a Cp group substituted with a methyl group and ethyl alcohol is an ethyl group substituted with an -OH group.

[0016] An "olefin," alternatively referred to as "alkene," is a linear, branched, or cyclic compound of carbon and hydrogen having at least one double bond. For purposes of this specification and the claims appended thereto, when a polymer or copolymer is referred to as comprising an olefin, including, but not limited to, ethylene and or propylene, the olefin present in such polymer or copolymer is the polymerized form of the olefin. For example, when a copolymer is said to have an "ethylene" content of 35 wt% to 55 wt%, it is understood that the mer unit in the copolymer is derived from ethylene in the polymerization reaction and said derived units are present at 35 wt% to 55 wt%, based upon the weight of the copolymer. A "polymer" has two or more of the same or different mer units. A "homopolymer" is a polymer having mer units that are the same. A "copolymer" is a polymer having two or more mer units that are different from each other. An ethylene polymer is a polymer having at least 50 mol% of ethylene, a propylene polymer is a polymer having at least 50 mol% of propylene, and so on.

[0017] Room temperature is defined as 25°C unless otherwise specified.

[0018] Unless otherwise stated, Mn, Mw and Mz are determined using the following Gel Permeation Chromatography (GPC) method using a High Temperature Size Exclusion Chromatograph (SEC, either from Waters Corporation or Polymer Laboratories), equipped with a differential refractive index detector (DRI). Molecular weight distribution (MWD) is Mw (GPC)/ Mn (GPC). Experimental details, are described in: T. Sun, P. Brant, R. R. Chance, and W. W. Graessley, Macromolecules , Volume 34, Number 19, pp. 6812-6820, (2001) and references therein. Three Polymer Laboratories PLgel 10mm Mixed-B columns are used. The nominal flow rate is 0.5 cm³/min and the nominal injection volume is 300 μί. The various transfer lines, columns and differential refractometer (the DRI detector) are contained in an oven maintained at 135°C. Solvent for the SEC experiment is prepared by dissolving 6 grams of butylated hydroxy toluene as an antioxidant in 4 liters of Aldrich reagent grade 1,2,4 trichlorobenzene (TCB). The TCB mixture is then filtered through a 0.7 μιη glass pre-filter and subsequently through a 0.1 μιη Teflon filter. The TCB is then degassed with an online degasser before entering the SEC. Polymer solutions are prepared by placing dry polymer in a glass container, adding the desired amount of TCB, then heating the mixture at 160°C with continuous agitation for about 2 hours. All quantities are measured gravimetrically. The TCB densities used to express the polymer concentration in mass/volume units are 1.463 g/mL at room temperature and 1.324 g/mL at 135°C. The injection concentration is from 1.0 to 2.0 mg/mL, with lower concentrations being used for higher molecular weight samples. Prior to running each sample the DRI detector and the injector are purged. Flow rate in the apparatus is then increased to 0.5 mL/minute, and the DRI is allowed to stabilize for 8 to 9 hours before injecting the first sample. The concentration, c, at each point in the chromatogram is calculated from the baseline-subtracted DRI signal, I_DR1, using the following equation:

c = K_DRII_DRI/(dn/dc)

where K_DRJ is a constant determined by calibrating the DRI, and (dn/dc) is the refractive index increment for the system. The refractive index, n = 1.500 for TCB at 135°C and λ = 690 nm. For purposes of this invention and the claims thereto, (dn/dc) = 0.104 for propylene polymers and ethylene polymers, and 0.1 otherwise. Units of parameters used throughout this description of the SEC method are: concentration is expressed in g/cm³, molecular weight is expressed in g/mol, and intrinsic viscosity is expressed in dL/g.

BULKY LIGAND METALLOCENE CATALYST COMPOSITIONS

[0048] A metallocene catalyst is defined as an organometallic compound with at least one π-bound cyclopentadienyl moiety (or substituted cyclopentadienyl moiety) and more frequently two π-bound cyclopentadienyl moieties or substituted cyclopentadienyl moieties. The supported or unsupported organoaluminum compounds described herein may be used to activate bulky ligand metallocene catalyst compositions. Generally, these catalyst compounds include half and full sandwich compounds having one or more bulky ligands bonded to at least one metal atom.

[0049] Typical bulky ligand metallocene compounds are described as containing one or more bulky ligand(s) and one or more leaving group(s) bonded to at least one metal atom. Suitable metallocene catalysts are described as follows and are also described in WO2005/068515, published July 28, 2005, filed on November 3, 2004 with an International Application No. PCT/US2004/036988, the contents of which are incorporated herein in their entirety for all purposes.

[0050] The bulky ligands may be open, acyclic, fused ring(s) or ring system(s), or a combination thereof. The ring(s) or ring system(s) of these bulky ligands are typically composed of atoms selected from Groups 13 to 16 atoms of the Periodic Table of the Elements. Preferably the atoms are selected from the group consisting of carbon, nitrogen, oxygen, silicon, sulfur, phosphorus, germanium, boron and aluminum or a combination thereof. Most preferably the ring(s) or ring system(s) are composed of carbon atoms such as, but not limited to, cyclopentadienyl ligands or cyclopentadienyl-type ligand structures.

Solid Support Materials

[0075] Preferred ion-exchange layered silicate useful in the present invention are silicate compounds having crystal structures wherein layers formed by strong ionic and covalent bonds are laminated in parallel with weak ionic bonding, and the ions contained between the layers are exchangeable. Most ion-exchange layered silicates naturally occur as the main component of clay minerals, but these ion-exchange layered silicates may be artificially synthesized materials. Preferred ion-exchange layered silicates useful in this invention include natural or synthetic montmorillonite, nontronite, beidellite, volkonskoite, laponite, hectorite, saponite, sauconite, stevensite, vermiculite, halloysite, aluminate oxides, bentonite, kaolinite, dickite, smectic clays, mica, magadiite, kenyaite, octosilicate, kanemite, makatite, attapulgite, sepiolite, zeolitic layered materials (such as ITQ-2, MCM-22, and ferrierite precursors) and mixtures thereof. In a preferred embodiment, the ion-exchange layered silicate is acidified by contacting with an acid (such as sulfuric acid, hydrochloric acid, a carboxylic acid, an amino acid, or the like.)

[0076] Preferred ion-exchange layered silicates useful in this invention include those having a 1 : 1 type structure or a 2: 1 type structure. Examples of the ion-exchange layered silicate include layered silicates having a 1 : 1 type structure or a 2: 1 type structure as described in "Clay Mineralogy" written by R. E. Grim (published by McGraw Hill in 1968) and "Chemistry of Clays and Clay Minerals" written by A. C. Newman (published by John Wiley and Sons: New York in 1987). The 1 : 1 type structure is a structure formed by laminating 1 : 1 layered structures having one layer of tetrahedral sheet and one layer of octahedral sheet combined as described in the above literature "Clay Mineralogy", and the 2: 1 type structure is a structure formed by laminating 2: 1 layered structures having one layer of octahedral sheet sandwiched between two layers of tetrahedral sheets. Examples of ion- exchange layered silicate comprising the 1 : 1 layer as the main constituting layer include kaolin group silicates such as dickite, nacrite, kaolinite, metahalloysite, halloysite or the like, and serpentine group silicates such as chrysotile, lizardite, antigorite or the like. Examples of ion-exchange layered silicate comprising the 2: 1 layer as the main constituting layer include smectite group silicates such as montmorillonite, beidellite, nontronite, saponite, hectorite, stephensite or the like, vermiculite group silicates such as vermiculite or the like, mica group silicates such as mica, illite, sericite, glauconite or the like, and attapulgite, sepiolite, palygorskite, bentonite, pyrophyllite, talc, chlorites and the like. Mixed layer silicates are also included. In some embodiments, an ion-exchange layered silicate having the 2: 1 type structure is preferable. In another preferred embodiment, a smectite group silicate is used and in a particularly preferable example the ion exchange layered silicate comprises montmorillonite.

Chemical Treatment of Ion-Exchange Layered Silicate

[0077] The chemical treatment of an ion-exchange layered silicate is carried out by bringing it in contact with an acid, a salt, an alkali, an oxidizing agent, a reducing agent or a treating agent containing a compound intercalatable between layers of an ion-exchange layered silicate. The intercalation means to introduce other material between layers of a layered material, and the material to be introduced is called a guest. Among these treatments, acid treatment or salt treatment is particularly preferable.

[0078] A common effect achieved by chemical treatment is to exchange an intercalation cation with other cations, and in addition to this effect, the following various effects can be achieved by various chemical treatments. For example, acid treatment removes impurities on the surface of silicate, and cations such as Al, Fe, Mg or the like, in a crystal structure are eluted, thereby increasing the surface area. This treatment enhances the acid strength and acidity of the layered silicate.

[0079] Alkali treatment destroys a crystal structure of a clay mineral, and changes a structure of the clay mineral. Also, intercalation or salt treatment forms an ion composite, a molecule composite, an organic derivative or the like, and changes a surface area or a distance between layers. By using an ion-exchange reaction, an exchangeable intercalated cation between layers can be replaced by other large bulky ions, thereby producing a layered material having the distance between layers enlarged. Thus, the bulky ions have a function as a column supporting the layered structure, and are called pillars.

[0080] In embodiments of the invention, one, two, three, or more kinds of members selected from the group consisting of acids, salts, alkalis, oxidizing agents, reducing agents and compounds intercalatable between layers of an ion-exchange layered silicate may be combined and used as treating agents. Also, acids, salts, alkalis, oxidizing agents, reducing agents and compounds intercalatable between layers of an ion-exchange layered silicate may be respectively used in a combination of two or more members. Among them, a combination of a salt treatment and an acid treatment is particularly preferable.

[0081] The above-mentioned various treating agents may be used as a treating agent solution by dissolving in an appropriate solvent, or it is possible to use a treating agent itself as a solvent. Examples of a usable solvent include water, alcohols, aliphatic hydrocarbons, aromatic hydrocarbons, esters, ethers, ketones, aldehydes, furans, amines, dimethylsulfoxide, dimethylformamide, carbon disulfide, nitrobenzene, pyridines or their halides. A concentration of a treating agent in a treating agent solution is preferably from 0.1 to 100 wt.%, more preferably from 5 to 50 wt.%. If the treating agent concentration is within these ranges, a time required for treatment becomes shorter and an efficient production is possible.

Chemical Treatment Protocol

Acid Treatment

[0082] An acid treatment removes impurities on the surface or ion-exchanges a cation present between layers, and in addition to this function, the acid treatment elutes a part or whole of cations such as Al, Fe, Mg or the like in a crystal structure. Examples of an acid used in acid treatment include hydrochloric acid, nitric acid, sulfuric acid, phosphoric acid, acetic acid, and oxalic acid and the like. Particularly, it is preferable to use an inorganic acid. Usually the acid is used in a form of an acid aqueous solution. The acid used in the treatment may be a mixture of at least two kinds of acids. In a preferred embodiment, the acid used herein is sulfuric acid.

[0083] A particular preferable embodiment of the present invention is to carry out a treatment with an acid having a specific concentration. Any concentration of acid may be used, however higher acid concentrations (and higher temperatures) are more efficient. In particular using an acid concentration of more than 5 weight % (based upon the weight of the acid, any liquid diluent or solvent and the ion exchange layered silicate present), preferably more than 10 weight %, more preferably more than 15 weight % has been found to be effective. In a preferred embodiment, the treatment is performed at temperatures of more than 50°C, preferably more than 70°C, more preferably at more than 90°C. The treatment preferably is allowed to react for 5 minutes to 10 hours, more preferably 30 minutes to 8 hours, more preferably 1 to 6 hours. In a particularly preferred embodiment, the treatment occurs at 90°C or more for 2 to 6 hours using an acid concentration of more than 15 weight %. In another particularly preferred embodiment, the treatment occurs at 100°C or more for 2 to 4 hours using an acid concentration of more than 15 weight %.

[0084] An acid used for the concentrated acid treatment may be the same as those used in an ordinary acid treatment, but is preferably sulfuric acid, nitric acid or hydrochloric acid, more preferably sulfuric acid.

Salt Treatment

[0085] Further, one may carry out a salt treatment. The salt treatment means a treatment carried out for the purpose of exchanging cations in an ion-exchange layered silicate. The treating conditions with a salt are not specifically limited, but it is preferable to carry out the salt treatment under conditions of a salt concentration of from 0.1 to 50 wt.%, a treating temperature of from room temperature to a boiling point and a treating time of from 5 minutes to 24 hours in such a manner as to elute at least a part of materials constituting an ion-exchange layered silicate. Also, the salt may be used in an organic solvent such as toluene, n-heptane, ethanol or the like, or may be used in the absence of a solvent if it is liquid-like at the treating temperature, but it is preferably used as an aqueous solution. However, depending on the kind of a salt employed, the salt treatment achieves an effect similar to an acid treatment.

[0086] In preferred embodiments of the invention, one can ion exchange at least 40%, preferably at least 60% of ion exchangeable cations of Group 1 metals contained in an ion- exchange layered silicate with cations dissociated from the salts as described above. After carrying out the above chemical treatment, it is preferable to remove ions eluted from the treatment and an excess amount of a treating agent. For this operation, water or an organic solvent is generally used. After dehydrating, drying is carried out generally at a drying temperature of from 100 to 800°C, preferably from 150 to 600°C.

Drying of Chemically Treated Ion-Exchange Layered Silicate

[0087] These ion-exchange layered silicates can change their properties depending on a drying temperature employed even when their structures are not destroyed, and it is therefore preferable to change a drying temperature depending on their uses. The drying period is usually in a range of from 1 minute to 24 hours, preferably from 5 minutes to 6 hours, and a drying atmosphere is preferably dry air, dry nitrogen, dry argon, or carried out under reduced pressure. A drying method is not specifically limited, but various methods may be employed. Pore Size / Distribution

[0088] The evaluation of the pore size distribution useful herein employs the desorption isotherm (by nitrogen adsorption-desorption method). The desorption isotherm is a curve obtained while reducing the relative pressure. The desorption isotherm shows a lower relative pressure to the same desorbed gas amount as compared with adsorption isotherm, and consequently shows a lower free energy state, and is generally considered to be closer to a state of real thermodynamic stability.

[0089] In one embodiment, an ion-exchange layered silicate with any pore size and or any pore size distribution may be used. In another embodiment, included in this invention is the preferred pore size distributions of the ion-exchange layered silicate as described in US 2003/0027950 Al. Where D_m (from differential values of pore volumes) represents a pore size diameter showing a maximum peak intensity and is generally expressed as "most frequently appearing pore diameter", DyM represents a maximum peak intensity and D_ml 2 represents a pore size diameter on the smaller diameter side corresponding to a point, the peak intensity of which is 1/2 of the maximum peak intensity. A pore diameter D_m 2 is present at least one respectively on both sides of D_m, i.e. on the larger diameter side of D_m and on the smaller diameter side of D_m, but a value on the smaller diameter side is taken as the D_ml 2 value in the present invention. Also, if there are a plurality of D_ml 2 values on the smaller diameter side, the largest value is employed for calculation. In one embodiment of the invention, the D_ml 2 'D_m can range from 0.1 to 0.9. In another embodiment, a D_ml 2'D_m value is preferably at least 0.68, more preferably at least 0.70.

[0090] An ion-exchange layered silicate may have a predetermined pore size, but its pore size is sufficiently large to accept a metallocene complex, an organoaluminum compound, and a monomer. Accordingly, these compounds participating in the reaction easily enter into pores in respective stages of formation of a catalyst, activation, prepolymerization and polymerization, and complexes are highly dispersed in carriers, and consequently metallocene catalyst active sites are uniformly formed. In a preferred embodiment, the ion exchange layered silicate has a pore size that is sufficiently large enough that the catalyst compound and the organoaluminum may freely enter and diffuse evenly within the particle. Preferred pore sizes include 40 Angstroms to 500 Angstroms, preferably 50 Angstroms to 300 Angstroms, more preferably 70 to 200 Angstroms.

Carrier Strength

[0091] In one embodiment, the ion exchange layered silicate may have a compression fracture strength (also called average crushing strength) as measured by a minute compression tester of 3 to 20 MPa. Preferably, the average crushing strength is at least 5 MPa, more preferably at least 7 MPa. In addition, the upper limit of the ion exchange layered silicate strength is preferably an average crushing strength of at most 20 MPa, more preferably at most 18 MPa.

Olefin Polymerization Catalyst System

[0092] In the present invention, an olefin polymerization catalyst system can be prepared by contacting the organoaluminum compounds described herein with a catalyst compound (also called catalyst precursor compounds, pre-catalyst compounds or catalyst precursors). In one embodiment, a supported catalyst system may be prepared, generally, by the reaction of the organoaluminum compound with the addition of a metallocene catalyst, followed by addition of an ion-exchange layered silicate. Alternately, a supported catalyst system may be prepared, generally, by the reaction of the organoaluminum compound, an ion-exchange layered silicate, and then adding one or more metallocene catalysts.

[0093] In a preferred embodiment, the ion exchange layered silicate is combined with the organoaluminum and thereafter is combined with the catalyst.

[0094] Contact between an ion-exchange layered silicate and an organoaluminum compound and/or metallocene can be carried out under an inert gas atmosphere such as nitrogen in a solvent of an inert hydrocarbon such as hexane, heptane, pentane, cyclohexane, benzene, toluene, xylene or the like, and the solvent may be used alone or in a mixture of two or more.

[0095] An amount of an organoaluminum compound used is preferably from 0.01 to 1000 mmol, more preferably from 0.1 to 100 mmol, per 1 g of an ion-exchange layered silicate.

[0096] A concentration of an ion-exchange layered silicate in a solvent is preferably from 0.001 to 100 g/mL, more preferably form 0.01 to 10 g/mL, and a concentration of an organoaluminum compound is preferably from 0.001 to 100 mmol/mL, more preferably from 0.01 to 10 mmol.

[0097] Contacting may be carried out by dispersing an ion-exchange layered silicate in a solvent and then bringing an organoaluminum compound in contact therewith. Alternatively, contacting may be carried out by adding an organoaluminum compound to a solvent and then dispersing an ion-exchange layered silicate therein.

[0098] The contacting treatment is carried out generally at a temperature of from -50°C to a boiling point of a solvent, preferably from 0°C to a boiling point of a solvent. The contacting time is from 1 minute to 48 hours, preferably from 1 minute to 24 hours.

[0099] The order of contacting an organoaluminum compound with an ion-exchange layered silicate is not specifically limited as far as the object of the present invention is achieved, but it is more effective to carry out the contacting treatment after chemical treatment of the silicate or preferably after drying carried out after the chemical treatment.

[00100] Also, the order of contacting treatment step of an organoaluminum compound and an ion-exchange layered silicate and the granulation step of an ion-exchange layered silicate is not specifically limited as far as the object of the present invention is achieved, but it is preferable to carry out the treatment with an organoaluminum compound after granulating the silicate.

[00101] Further, it is possible to enhance the effect of the present invention by combining the above-mentioned respective treatments. Thus, after controlling a particle size distribution and a carrier particle strength by granulating an ion-exchange layered silicate, a carrier obtained through the following Step 1 and Step 2 is used as a catalyst component for olefin polymerization.

[00102] Step 1 : after granulating an ion-exchange layered silicate, the silicate is treated with an acid having an acid concentration as described above.

[00103] Step 2: after carrying out step 1, the silicate is treated with an organoaluminum compound which is any organoaluminum compound from the discussion above.

[00104] A metallocene can be added with, prior to, or after the silicate is treated with an organoaluminum compound.

One or more of the monomers used in the polymerization may be utilized as a solvent and/or diluent, generally in homogeneous polymerizations in the liquid monomer or monomers. Hydrocarbyl solvents are also suitable, both aliphatic and aromatic, including hexane and toluene. Bulk and slurry processes may typically be accomplished by contacting the catalysts with a slurry of liquid monomer, the catalyst system being supported. Gas phase processes may use the supported catalyst and may be conducted in any manner known to be suitable for producing ethylene homopolymers or copolymers via coordination polymerization. Illustrative examples may be found in US Patents 4,543,399, 4,588,790, 5,028,670, 5,382,638, 5352,749, 5,436,304, 5,453,471, 5,463,999, and WO 95/07942.

Data was recorded using a maximum pulse width of 45°, 8 seconds between pulses and signal averaging either 8 or 16 transients. The spectrum were normalized to protonated tetrachloroethane in the deuterated tetrachloroethane, which is expected to show a peak at 6.0 ppm.

[00127] The catalyst, (HP(tBu)₂)₂Ru(C₅H₈)Cl₂, was synthesized as described in US 2012/0309998 Al, Dec 6, 2012. The olefin described as ROCM-(DCPD, 1-pentene) was obtained by the ring opening cross metathesis of 1-pentene and dicyclopentadiene, (145°C @ 60 mTorr) as described in USSN 13/209,242 April 26, 2013.

[00128] ROCM is defined to mean ring opening cross metathesis. ROCM-(olefin A, olefin B) is a Polymer produced by the ROCM of olefin A and olefin B.

Synthesis of ROCM-(norbornene, 1-hexene):

[00129] l-hexene(15.0 g, 178 mmol, 1.30eq) and the ROCM catalyst [(HP(tBu)₂)₂Ru(C₅H₈)Cl₂] (6.0mg, O.Ol lmmol, 0.0008 eq) were added together in a lOOmL round bottom flask and heated to 40°C. Norbornene (12.9 g 94.1 mmol, 1 eq) was dissolved in approximately 5mL of toluene and added dropwise to the stirring solution in a heating block set at room temperature. The thermocouple connected to the heating block and the flask indicated an exothermic reaction; at 50°C the round bottom was placed in the freezer (-35°C) for 1 hour to cool down. After further stirring for lhr at 40°C, then overnight (16 hrs) at room temperature; the reaction was taken out of the box and distilled. The distillation was checked periodically via NMR in order to confirm removal of excess 1-hexene and toluene. The product was distilled with a short path distillation apparatus, then placed on a rotavap in order to remove excess toluene. NMR analysis was a mixture of approximately 1 norbornene unit (21%) and 2 norbornene units (79%). 7.47 grams of product were collected.

Small Scale Polymerization Procedures

1. Propylene Polymerizations

General Procedure for Small Scale Solution Polymerization

[00137] Unless stated otherwise, ethylene homopolymerizations were carried out in a parallel, pressure reactor, as generally described in US 6,306,658; US 6,455,316; US 6,489, 168; WO 00/09255; and Murphy et al., J. Am. Chem. Soc, 2003, 125, pp. 4306-4317, each of which is fully incorporated herein by reference for US purposes to the extent not inconsistent with this disclosure. Although the specific quantities, temperatures, solvents, reactants, reactant ratios, pressures, and other variables are frequently changed from one polymerization run to the next, the following describes a typical polymerization performed in a parallel, pressure reactor.

[00138] 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, then ethylene (135 psi (931 kPa)) was added to each vessel. Then solvent (typically isohexane) was added to bring the total reaction volume, including the subsequent additions, to 5 mL and the reactor vessels were heated to their set temperature (70°C and 90°C) (see table). At this time scavenger and/or co-catalyst, such as tri-n-octylaluminum or Al-ROCM(DCPD, l-pentene)3 in toluene (approximately 1 micromole) was added.

[00139] The contents of the vessel were stirred at 800 rpm. An activator solution (typically 1.0-1.2 molar equivalents of dimethyl anilinium tetrakis-pentafluorophenyl) was then injected into the reaction vessel along with 500 microliters of toluene, followed by a toluene solution of catalyst compound (typically 0.40 mM in toluene, usually 20-40 nanomols of catalyst) and another aliquot of toluene (500 microliters). Equivalence is determined based on the mol equivalents relative to the moles of the transition metal in the catalyst complex.

[00140] The reaction was then allowed to proceed until a pre-determined amount of pressure had been taken up by the reaction. Alternatively, the reaction may be allowed to proceed for a set amount of time. At this point, the reaction was quenched by pressurizing the vessel with compressed air. After the polymerization reaction, 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.

[00141] To determine various molecular weight related values by GPC, high temperature size exclusion chromatography was performed using an automated "Rapid GPC" system as generally described in US 6,491,816; US 6,491,823; US 6,475,391; US 6,461,515; US 6,436,292; US 6,406,632; US 6, 175,409; US 6,454,947; US 6,260,407; and US 6,294,388; each of which is fully incorporated herein by reference for US purposes. This apparatus has a series of three 30 cm x 7.5 mm linear columns, each containing PLgel 10 um, Mix B. The GPC system was calibrated using polystyrene standards ranging from 580 - 3,390,000 g/mol. The system was operated at an eluent flow rate of 2.0 mL/minutes and an oven temperature of 165°C. 1,2,4-trichlorobenzene was used as the eluent. The polymer samples were dissolved in 1,2,4-trichlorobenzene at a concentration of 0.1 - 0.9 mg/mL. 250 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.
