     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     Embodiments of the present invention generally relate to olefin polymerization catalysts. More particularly, embodiments of the present invention generally relate a catalyst system containing a metal atom bound to at least two Group 15 atoms and their use in gas or slurry phase to produce polyolefins. 
     2. Description of the Related Art 
     Advances in polymerization and catalysis have produced new polymers having improved physical and mechanical properties useful in a wide variety of products and applications. With the development of new catalysts, the choice of polymerization, such as solution, slurry, high pressure or gas phase, for producing a particular polymer has been greatly expanded. Advances in polymerization technology have also provided more efficient, highly productive and economically enhanced processes. 
     Metallocene catalysts have been used to produce resins having desirable product properties. While these resins have excellent toughness properties, particularly dart impact properties, these resins can be difficult to process. One approach to improve the processing of such metallocene catalyzed polyethylenes has been to blend them with another polymer. While the polymer blend tends to be more processable, the blend is expensive and adds a cumbersome step to the manufacturing process. 
     Another approach has been to produce two polymers together at the same time in the same reactor using two different catalysts. For example, WO 99/03899 discloses using a typical metallocene catalyst and a conventional Ziegler-Natta catalyst in the same reactor to produce a bimodal MWD HDPE. Other catalysts, such as anionic, multidentate heteroatom ligands, have also been used in mixed catalyst system. For example, U.S. Pat. No. 5,576,460 describes a preparation of arylamine ligands. U.S. Pat. No. 5,889,128 discloses a process for the living polymerization of olefins using initiators having a metal atom and a ligand having two group 15 atoms and a group 16 atom or three group 15 atoms. EP 893 454 A1 describes titanium transition metal amide compounds. U.S. Pat. No. 5,318,935 discusses amido transition metal compounds and catalyst systems for producing isotactic polypropylene. U.S. Pat. No. 5,506,184 discloses polymerization catalysts containing bidentate and tridentate ligands. 
     Polymers produced by two different catalysts types, however, exhibit unpredictable characteristics. The polymers produced from two different catalysts can exhibit different physical and mechanical properties compared to the individual polymers produced separately from each catalyst and blends thereof. This unpredictability may occur due to competition or other influence between the catalyst or catalyst systems used. This unpredictability may also occur due to differences in solubility of the individual catalyst components, reaction kinetics of the individual catalyst components, and the rate of decay of the individual catalyst components, just to name a few. There is a need, therefore, for a combination of compatible catalysts capable of producing polyolefin polymers having desirable combinations of processing, mechanical, and optical properties.

     A heteroatom containing group may be any heteroatom or a heteroatom bound to carbon, silicon or another heteroatom. Preferred heteroatoms include boron, aluminum, silicon, nitrogen, phosphorus, arsenic, tin, lead, antimony, oxygen, selenium, and tellurium. Particularly preferred heteroatoms include nitrogen, oxygen, phosphorus, and sulfur. Even more particularly preferred heteroatoms include nitrogen and oxygen. The heteroatom itself may be directly bound to the phenoxide ring or it may be bound to another atom or atoms that are bound to the phenoxide ring. The heteroatom containing group may contain one or more of the same or different heteroatoms. Preferred heteroatom containing groups include imines, amines, oxides, phosphines, ethers, ketones, oxoazolines heterocyclics, oxazolines, thioethers, and the like. Particularly preferred heteroatom containing groups include imines. Any two adjacent R groups may form a ring structure, preferably a 5 or 6 membered ring. Likewise the R groups may form multi-ring structures. In one embodiment any two or more R groups do not form a 5 membered ring. 
     In a preferred embodiment the heteroatom substituted phenoxide transition metal compound is an iminophenoxide Group 4 transition metal compound, and more preferably an iminophenoxidezirconium compound. 
     Supported Catalyst Systems 
     The mixed catalyst system may further include a support or carrier. Each component of the mixed catalyst system may be supported on a support or carrier or each catalyst component may be unsupported. In other words, any one, none, or all of the catalyst components may be supported or unsupported. Further, one of the catalyst components (e.g., the non-metallocene) may reside on one collection of support particles, and another catalyst component (e.g., the metallocene) may reside on another collection of support particles. The support for each of the individual components may be the same or different. 
     The term “supported” as used herein refers to one or more compounds that are deposited on, contacted with, vaporized with, bonded to, or incorporated within, adsorbed or absorbed in, or on, a support or carrier. The terms “support” or “carrier” for purposes of this specification are used interchangeably and are any support material, preferably a porous support material, including inorganic or organic support materials. Non-limiting examples of inorganic support materials include inorganic oxides and inorganic chlorides. Other carriers include resinous support materials such as polystyrene, functionalized or crosslinked organic supports, such as polystyrene, divinyl benzene, polyolefins, or polymeric compounds, zeolites, talc, clays, or any other organic or inorganic support material and the like, or mixtures thereof. 
     The support materials utilized may be any of the conventional support materials. Preferably the supported material is a porous support material, for example, talc, inorganic oxides and inorganic chlorides. Other support materials include resinous support materials such as polystyrene, functionalized or crosslinked organic supports, such as polystyrene divinyl benzene polyolefins or polymeric compounds, zeolites, clays, or any other organic or inorganic support material and the like, or mixtures thereof. 
     The preferred support materials are inorganic oxides that include those Group 2, 3, 4, 5, 13 or 14 metal oxides. The preferred supports include silica, fumed silica, alumina, silica-alumina and mixtures thereof. Other useful supports include magnesia, titania, zirconia, magnesium chloride, montmorillonite, phyllosilicate, zeolites, talc, clays and the like. Also, combinations of these support materials may be used, for example, silica-chromium, silica-alumina, silica-titania and the like. Additional support materials may include those porous acrylic polymers. Other support materials include nanocomposites, aerogels, spherulites, and polymeric beads. Another support is fumed silica available under the trade name Cabosil™ TS-610, available from Cabot Corporation. Fumed silica is typically a silica with particles 7 to 30 nanometers in size that has been treated with dimethylsilyldichloride such that a majority of the surface hydroxyl groups are capped. 
     In another embodiment, any of the conventionally known inorganic oxides, such as silica, support materials that retain hydroxyl groups after dehydration treatment methods will be suitable in accordance with the invention. Because of availability, both of silica and silica containing metal oxide based supports, for example, silica-alumina, are preferred. Silica particles, gels and glass beads are most typical. 
     These metal oxide compositions may additionally contain oxides of other metals, such as those of Al, K, Mg, Na, Si, Ti and Zr and should preferably be treated by thermal and/or chemical means to remove water and free oxygen. Typically such treatment is in a vacuum in a heated oven, in a heated fluidized bed or with dehydrating agents such as organo silanes, siloxanes, alkyl aluminum compounds, etc. The level of treatment should be such that as much retained moisture and oxygen as is possible is removed, but that a chemically significant amount of hydroxyl functionality is retained. Thus calcining at up to 800° C. or more up to a point prior to decomposition of the support material, for several hours is permissible, and if higher loading of supported anionic activator is desired, lower calcining temperatures for lesser times will be suitable. Where the metal oxide is silica, loadings to achieve from less than 0.1 mmol to 3.0 mmol activator/g SiO 2  are typically suitable and can be achieved, for example, by varying the temperature of calcining from 200° C. to 1,000° C., such as from 300° C. to 900° C., 400° C. to 875° C., 500° C. to 850° C., 600° C. to 825° C., 700° C. to 800° C., and any combination of any limit with any lower limit. 
     The tailoring of hydroxyl groups available as attachment sites in this invention can also be accomplished by the pre-treatment with a less than stoichiometric amount of a chemical dehydrating agent. If calcining temperatures below 400° C. are employed, difunctional coupling agents (e.g., (CH 3 ) 3 SiCl 2 ) may be employed to cap hydrogen bonded pairs of silanol groups which are present under the less severe calcining conditions. Similarly, use of the Lewis acid in excess of the stoichiometric amount needed for reaction with the transition metal compounds will serve to neutralize excess silanol groups without significant detrimental effect for catalyst preparation or subsequent polymerization. 
     In another embodiment, the support is a polymeric support, including hydroxyl-functional-group-containing polymeric substrates, but functional groups may be any of the primary alkyl amines, secondary alkyl amines, and others, where the groups are structurally incorporated in a polymeric chain and capable of a acid-base reaction with the Lewis acid such that a ligand filling one coordination site of the aluminum is protonated and replaced by the polymer incorporated functionality. See, for example, the functional group containing polymers of U.S. Pat. No. 5,288,677. 
     It is preferred that the support material, most preferably an inorganic oxide, has a surface area in the range of from about 10 to about 700 m 2 /g, pore volume in the range of from about 0.1 to about 4.0 cc/g and average particle size in the range of from about 5 to about 500 μm. More preferably, the surface area of the support material is in the range of from about 50 to about 500 m 2 /g, pore volume of from about 0.5 to about 3.5 cc/g and average particle size of from about 10 to about 2001m. The average pore size of the carrier is typically in the range of from 10 to 1000 Å, preferably 50 to about 500 Å, and most preferably 75 to about 350 Å. 
     The support materials may be treated chemically, for example with a fluoride compound as described in WO 00/12565. Other supported activators are described in for example WO 00/13792 that refers to supported boron containing solid acid complex. 
     In another embodiment, an antistatic agent or surface modifier that is used in the preparation of the supported catalyst system as described in PCT publication WO 96/11960 may be used with catalyst systems including the activator compounds described herein. The catalyst systems may also be prepared in the presence of an olefin, for example 1-hexene. 
     In another embodiment, the activator and/or catalyst system may be combined with a carboxylic acid salt of a metal ester, for example aluminum carboxylates such as aluminum mono, di- and tri-stearates, aluminum octoates, oleates and cyclohexylbutyrates, as described in U.S. Pat. Nos. 6,300,436 and 6,306,984. 
     Method For Supporting 
     Various methods can be used to affix two catalyst components to a support to form the mixed catalyst system. For example, one procedure includes forming a mixture (solution or slurry) of the first catalyst component and a non-polar hydrocarbon, and contacting this mixture with a mixture (solution or slurry) that includes the second catalyst component. 
     In one aspect, the support is prepared by heating support particles at a dehydration temperature of up to 600° C., or to 800° C. or more when preparing an “enhanced support,” resulting in a support having a modified chemical structure, e.g., a reduced number of hydroxyl groups. The higher dehydration temperatures are preferred. 
     The support is preferably an inorganic material such as silicon oxide (silica) or aluminum oxide. The support material can be a dry powder, and in certain embodiments has an average particle size of from 1-500 microns, or more narrowly from 10-250 microns. The surface area of the support may range from 3 m 2/g to 600 m 2 /g or more. 
     A preferred support is an amorphous high surface area silica, such as Davison 952 or Sylopol® 955, sold by Davison Chemical Division of W.R. Grace and Company. Those silicas are in spherical form, prepared by a spray drying process, with a surface area of about 300 m 2 /g and a pore volume of about 1.65 cm 3 /g. A procedure for dehydrating the silica at 600° C. or more is set forth in U.S. Pat. No. 5,525,678. 
     A variety of non-polar hydrocarbons can be used to form the support slurry, but any non-polar hydrocarbon selected should remain in liquid form at all relevant reaction temperatures, and the ingredients used to form the first catalyst component should be at least partially soluble in the non-polar hydrocarbon. Accordingly, the non-polar hydrocarbon is considered to be a “solvent” herein, even though in certain embodiments the ingredients are only partially soluble in the hydrocarbon. For example, the organomagnesium compound, alcohol and transition metal compound of the first catalyst compound, described above, should be at least partially soluble, and preferably completely soluble, in that hydrocarbon solvent at the mixing temperatures described above. 
     Examples of suitable non-polar hydrocarbons include C 4 -C 10  linear or branched alkanes, cycloalkanes and aromatics. More specifically, a non-polar alkane can be isopentane, hexane, isohexane, n-heptane, octane, nonane, or decane; a non-polar cycloalkane such as cyclohexane; or an aromatic such as benzene, toluene, or ethylbenzene. Mixtures of different non-polar hydrocarbons can also be used. 
     The support slurry can be heated both during and after mixing of the support particles with the non-polar hydrocarbon solvent, but at the point when either or both of the catalysts are combined with the support slurry, the temperature of the slurry should be sufficiently low so that neither of the catalysts are inadvertently activated. Thus, the temperature of the support slurry (e.g., silica slurry) is preferably maintained at a temperature below 90° C., e.g., from 25 to 70° C., or even more narrowly from 40 to 60° C. 
     Activator 
     The term “activator” as used herein refers to any compound or component, or combination of compounds or components, capable of enhancing the ability of a catalyst to polymerize olefin monomers to form polyolefins. In certain embodiments, either or both of the catalyst components may be contacted with a catalyst activator, herein simply referred to as an “activator.” 
     The activator may be any one or a combination of compounds commonly employed to activate Group 15-containing catalysts. These include metal alkyls, hydrides, alkylhydrides, alkylhalides (such as alkyllithium compounds), dialkylzinc compounds, trialkylboron compounds, trialkylaluminum compounds, alkylaluminum halides, alkylaluminum and hydrides, and tetraalkylgermanium compounds. Preferably, this activator is trimethyl aluminum (TMA). The amount of activator is preferably sufficient to give a molar ratio of activator to metal in the catalyst component of about 3:1 to about 1000:1, preferably about 15:1 to about 300:1, and most preferably about 20:1 to about 100:1. 
     The activator may also be any one or a combination of compounds suitable for activating the metal sites of the metallocene type catalyst which may be different from the activator described above. This second activator is preferably a linear and/or cyclic aluminoxane species prepared from the interaction of R 3 Al and water, where R is a C 1 -C 12  linear, branched or cyclic alkyl, with the amount of water controlling the average molecular weight of the aluminoxane molecule. Preferably, methylaluminoxane (MAO) is used. 
     Polymerization Process 
     The activators and the polymerization catalysts described above, whether supported or not, are suitable for use in any prepolymerization and/or polymerization process over a wide range of temperatures and pressures. The temperatures may be in the range of from −60° C. to about 280° C., preferably from 50° C. to about 200° C. In one embodiment, the polymerization temperature is above 0° C., above 50° C., above 80° C., above 100° C., above 150° C., or above 200° C. In one embodiment, the pressures employed may be in the range from 1 atmosphere to about 500 atmospheres or higher. 
     Polymerization processes include solution, gas phase, slurry phase, and a high pressure process, or a combination thereof. Particularly preferred is a gas phase or slurry phase polymerization of one or more olefin(s) at least one of which is ethylene or propylene. 
     In one embodiment, the process is a solution, high pressure, slurry or gas phase polymerization process of one or more olefin monomers having from 2 to 30 carbon atoms, preferably 2 to 12 carbon atoms, and more preferably 2 to 8 carbon atoms. The invention is particularly well suited to the polymerization of two or more olefin monomers of ethylene, propylene, 1-butene, 1-pentene, 4-methyl-1-pentene, 1-hexene, 1-octene and 1-decene. 
     Other monomers useful include ethylenically unsaturated monomers, diolefins having 4 to 18 carbon atoms, conjugated or nonconjugated dienes, polyenes, vinyl monomers and cyclic olefins. Non-limiting monomers useful in the invention may include norbornene, norbornadiene, isobutylene, isoprene, vinylbenzocyclobutane, styrenes, alkyl substituted styrene, ethylidene norbornene, dicyclopentadiene and cyclopentene. 
     In another embodiment, a copolymer of ethylene is produced, where with ethylene, a comonomer having at least one alpha-olefin having from 4 to 15 carbon atoms, preferably from 4 to 12 carbon atoms, and most preferably from 4 to 8 carbon atoms, is polymerized in a gas phase process. 
     In another embodiment, ethylene or propylene is polymerized with at least two different comonomers, optionally one of which may be a diene, to form a terpolymer. 
     In one embodiment, the invention is directed to a polymerization process, particularly a gas phase or slurry phase process, for polymerizing propylene alone or with one or more other monomers including ethylene, and/or other olefins having from 4 to 12 carbon atoms. 
     Typically in a gas phase polymerization process, a continuous cycle is employed where in one part of the cycle of a reactor system, a cycling gas stream, otherwise known as a recycle stream or fluidizing medium, is heated in the reactor by the heat of polymerization. This heat is removed from the recycle composition in another part of the cycle by a cooling system external to the reactor. Generally, in a gas fluidized bed process for producing polymers, a gaseous stream containing one or more monomers is continuously cycled through a fluidized bed in the presence of a catalyst under reactive conditions. The gaseous stream is withdrawn from the fluidized bed and recycled back into the reactor. Simultaneously, polymer product is withdrawn from the reactor and fresh monomer is added to replace the polymerized monomer. 
     The reactor pressure in a gas phase process may vary from about 100 psig (690 kPa) to about 500 psig (3448 kPa), preferably in the range of from about 200 psig (1379 kPa) to about 400 psig (2759 kPa), more preferably in the range of from about 250 psig (1724 kPa) to about 350 psig (2414 kPa). 
     The reactor temperature in a gas phase process may vary from about 30° C. to about 120° C., preferably from about 60° C. to about 115° C., more preferably in the range of from about 70° C. to 110° C., and most preferably in the range of from about 70° C. to about 95° C. In another embodiment, the reactor temperature in a gas phase process is above 60° C. 
     Other gas phase processes include series or multistage polymerization processes. Gas phase processes may also include those described in U.S. Pat. Nos. 5,627,242, 5,665,818 and 5,677,375, and European publications EP-A-0 794 200 EP-B1-0 649 992, EP-A-0 802 202 and EP-B-634 421. 
     In another embodiment, the process may produce greater than 500 lbs of polymer per hour (227 Kg/hr) to about 200,000 lbs/hr (90,900 Kg/hr) or higher of polymer, preferably greater than 1000 lbs/hr (455 Kg/hr), more preferably greater than 10,000 lbs/hr (4540 Kg/hr), even more preferably greater than 25,000 lbs/hr (11,300 Kg/hr), still more preferably greater than 35,000 lbs/hr (15,900 Kg/hr), still even more preferably greater than 50,000 lbs/hr (22,700 Kg/hr) and most preferably greater than 65,000 lbs/hr (29,000 Kg/hr) to greater than 100,000 lbs/hr (45,500 Kg/hr). 
     A slurry polymerization process generally uses pressures in the range of from about 1 to about 50 atmospheres and even greater and temperatures in the range of 0° C. to about 120° C. In another embodiment, the slurry process temperature is above 100° C. In a slurry polymerization, a suspension of solid, particulate polymer is formed in a liquid polymerization diluent medium to which ethylene and comonomers and often hydrogen along with catalyst are added. The suspension including diluent is intermittently or continuously removed from the reactor where the volatile components are separated from the polymer and recycled, optionally after a distillation, to the reactor. The liquid diluent employed in the polymerization medium is typically an alkane having from 3 to 7 carbon atoms, preferably a branched alkane. The medium employed should be liquid under the conditions of polymerization and relatively inert. When a propane medium is used the process must be operated above the reaction diluent critical temperature and pressure. Preferably, a hexane or an isobutane medium is employed. 
     In another embodiment, the polymerization technique is referred to as a particle form polymerization, or a slurry process where the temperature is kept below the temperature at which the polymer goes into solution. Such technique is well known in the art, and described in for instance U.S. Pat. No. 3,248,179. Other slurry processes include those employing a loop reactor and those utilizing a plurality of stirred reactors in series, parallel, or combinations thereof. Non-limiting examples of slurry processes include continuous loop or stirred tank processes. Also, other examples of slurry processes are described in U.S. Pat. No. 4,613,484. 
     In another embodiment, this process may produce greater than 2000 lbs of polymer per hour (907 Kg/hr), more preferably greater than 5000 lbs/hr (2268 Kg/hr), and most preferably greater than 10,000 lbs/hr (4540 Kg/hr). In another embodiment the slurry reactor may produce greater than 15,000 lbs of polymer per hour (6804 Kg/hr), preferably greater than 25,000 lbs/hr (11,340 Kg/hr) to about 100,000 lbs/hr (45,500 Kg/hr). 
     Examples of solution processes are described in U.S. Pat. Nos. 4,271,060, 5,001,205, 5,236,998 and 5,589,555 and PCT WO 99/32525. 
     In one embodiment, the slurry or gas phase process is operated in the presence of the catalyst system described herein and in the absence of or essentially free of any scavengers, such as triethylaluminum, trimethylaluminum, tri-isobutylaluminum and tri-n-hexylaluminum and diethyl aluminum chloride, dibutyl zinc and the like. This process is described in PCT publication WO 96/08520 and U.S. Pat. Nos. 5,712,352 and 5,763,543. 
     In another embodiment, the method provides for injecting the catalyst system described herein into a reactor, particularly a gas phase reactor. In one embodiment the catalyst system is used in the unsupported form, preferably in a liquid form such as described in U.S. Pat. Nos. 5,317,036 and 5,693,727 and European publication EP-A-0 593 083. The polymerization catalyst in liquid form can be fed with an activator, and/or a support, and/or a supported activator together or separately to a reactor. The injection methods described in PCT publication WO 97/46599 may be utilized. 
     Where an unsupported catalyst system is used the mole ratio of the metal of the activator component to the metal of the catalyst compound is in the range of between 0.3:1 to 10, 000:1, preferably 100:1 to 5000:1, and most preferably 500:1 to 2000:1.

     The polymers, typically ethylene based polymers, have a density in the range of from 0.86 g/cc to 0.97 g/cc, preferably in the range of from 0.88 g/cc to 0.965 g/cc, more preferably in the range of from 0.900 g/cc to 0.96 g/cc, even more preferably in the range of from 0.905 g/cc to 0.95 g/cc, yet even more preferably in the range from 0.910 g/cc to 0.940 g/cc, and most preferably greater than 0.915 g/cc, preferably greater than 0.920 g/cc, and most preferably greater than 0.925 g/cc. Density is measured in accordance with ASTM-D-1238. 
     The polymers produced typically have a molecular weight distribution, a weight average molecular weight to number average molecular weight (M w /M n ) of greater than 1.5 to about 15, particularly greater than 2 to about 10, more preferably greater than about 2.2 to less than about 8, and most preferably from 2.5 to 8. The polymers may have a narrow molecular weight distribution and a broad composition distribution or vice-versa, and may be those polymers described in U.S. Pat. No. 5,798,427. 
     Also, the polymers typically have a narrow composition distribution as measured by Composition Distribution Breadth Index (CDBI). Further details of determining the CDBI of a copolymer are known to those skilled in the art. See, for example, PCT Patent Application WO 93/03093, published Feb. 18, 1993. The polymers in one embodiment have CDBI&#39;s generally in the range of greater than 50% to 100%, preferably 99%, preferably in the range of 55% to 85%, and more preferably 60% to 80%, even more preferably greater than 60%, still even more preferably greater than 65%.

     Bimodal Polymer Product 
     The polymers produced by the processes described herein, utilizing the mixed catalysts described herein, are preferably bimodal. The term “bimodal,” when used to describe a polymer or polymer composition, e.g., polyolefins such as polypropylene or polyethylene, or other homopolymers, copolymers or terpolymers, means “bimodal molecular weight distribution,” which term is understood as having the broadest definition persons in the pertinent art have given that term as reflected in printed publications and issued patents. For example, a single composition that includes polyolefins with at least one identifiable high molecular weight distribution and polyolefins with at least one identifiable low molecular weight distribution is considered to be a “bimodal” polyolefin, as that term is used herein. Preferably, other than having different molecular weights, the high molecular weight polyolefin and the low molecular weight polyolefin are essentially the same type of polymer, e.g., polypropylene or polyethylene. 
     The bimodal polymer products prepared using the mixed catalysts described herein can be used in a wide variety of products and end-use applications. The polymers produced by the process of the invention include linear low density polyethylene, elastomers, plastomers, high density polyethylenes, low density polyethylenes, medium density polyethylenes, polypropylene and polypropylene copolymers. 
     The bimodal polymers that can be made using the described processes can have a variety of compositions, characteristics and properties. At least one of the advantages of the catalysts is that the process utilized can be tailored to form a polymer composition with a desired set of properties. For example, it is contemplated that the polymers having the same properties as the bimodal polymer compositions in U.S. Pat. No. 5,525,678 can be formed. Also, the bimetallic catalysts described herein can be used in polymerization processes to form polymers having the same properties as the polymers in the following patents, 6,420,580; 6,388,115; 6,380,328; 6,359,072; 6,346,586; 6,340,730; 6,339,134; 6,300,436; 6,274,684; 6,271,323; 6,248,845; 6,245,868; 6,245,705; 6,242,545; 6,211,105; 6,207,606; 6,180,735; and 6,147,173.

     The bimodal polymers made by the described processes can in certain embodiments have a melt index (MI) or (I 2 ) as measured by ASTM-D-1238-E in the range from 0.01 dg/min to 1000 dg/min, more preferably from about 0.01 dg/min to about 100 dg/min, even more preferably from about 0.02 dg/min to about 50 dg/min, and most preferably from about 0.03 dg/min to about 0.1 dg/min. 
     The bimodal polymers made by the described processes can in certain embodiments have a melt index ratio (I 21 /I 2 ) (I 21  is measured by ASTM-D-1238-F) of from 40 to less than 500, more preferably from about 60 to less than 200.

     EXAMPLES 
     In order to provide a better understanding of the foregoing discussion, the following non-limiting examples are offered. Although the examples may be directed to specific embodiments of the present invention, they are not to be viewed as limiting the invention in any specific respect. All parts, proportions, and percentages are by weight unless otherwise indicated. All examples were carried out in dry, oxygen-free environments and solvents. All molecular weights are weight average molecular weight unless otherwise noted. Molecular weights (weight average molecular weight (M w ) and number average molecular weight (M n ) and (M z ) were measured by Gel Permeation Chromatography (GPC). 
     General Procedure for Synthesis 
     The catalyst synthesis and preparation is described below. All manipulations, unless otherwise noted, were performed in a nitrogen-filled glove box or using standard Schlenk techniques, unless stated otherwise. The reagents, particularly toluene and hexane were passed through individual sets of one gallon cylinders containing 13X molecular sieves and de-oxo catalyst before use. Deuterated benzene and toluene were dried over NaK alloy. Deuterated benzene, toluene, and tetrahydrofuran were degassed by the freeze-pump-thaw method. (The deuterated tetrahydrofuran was dried over sodium.) MOS (silica-supported MAO, 4.5 mmol Al/g) was obtained from Exxon. Kaydol mineral oil was purged with nitrogen while heated to 200° C. All other reagents were used as received from Aldrich. 
     In situ reagents were identified by comparison of starting reagents in comparable deuterated solvents. Quantitative internal standards for  1 H NMR spectra were referenced to protio impurities in the deuterio solvents.  19 F NMR spectra were referenced to −76.55 ppm CF 3 COOH external standard solution.  1 H NMR spectra were obtained from a QE-300 ( 1 H, 300 MHz) at room temperature.

On a Schlenk line with an argon atmosphere, the dark red heterogeneous solution was equipped with a reflux condenser and heated at 102° C. in an oil bath. After 19 hours, the reaction was removed from the oil bath and allowed to cool to room temperature. The wine colored heterogeneous solution was then transferred to a 2 liter separatory funnel and dissolved in 750 mL ether. The ether solution was washed with water (2×250 mL) and brine (2×250 mL) and then dried over magnesium sulfate. Solvent was removed in vacuo on rotovap. The yellow/amber oil was then placed on Schlenk line and left under vacuum overnight. When the flask was returned to normal atmosphere pressure, the oil turned to clumps.  1 H NMR confirmed the isolation of the desired product as yellow/amber solids (38.2 g, 98.7% yield).  1 H NMR (C 6 D 6 ): δ 0.73 (br s, 1H), 2.21 (s, 3H), 2.27 (s, 6H), 2.50 (t, 2H), 2.85 (t, 3H), 3.37 (br s, 1H), 6.83 (br s, 2H).

Volatiles were removed in vacuo from the homogeneous light amber solution leaving a tan sticky paste in the reaction flask. Triturations with hexane resulted in 0.559 g of a crude white solid. When these solids were dissolved in C 6 D 6  for  1 H NMR analysis, 0.032 g precipitated out of solution and 23.9 mg (9% yield) of the desired product was isolated.

     0.600 g (1.047 mmol) of (5) HN5Zr(NMe 2 ) 2  was slowly added to a flask charged with 2.3 g (8.97 mmol) of (4) C 6 F 5 OSi(CH 3 ) 3  and the amber yellow heterogeneous solution (solution was initially heterogeneous light yellow) was allowed to stir for 2 hours. An equivalent volume of hexane was added to the reaction flask and the hexane insoluble solids were isolated as a tan powder (0.132 g) which, by  1 H NMR (C 6 D 6 ) analysis, was the mono substituted product. After 26 days, crystals were observed in the hexane wash and isolated (0.212 g, 29% yield) by decanting away the liquid and drying by vacuum. 
     A proton NMR study revealed that the crystal contained the following molecules:
         [(C 6 Me 5 )NCH 2 CH 2 NHCH 2 CH 2 N(C 6 Me 5 )]Zr(OC 6 F 5 ) 2  and [(C 6 Me 5 )NCH 2 CH 2 NHCH 2 CH 2 N(C 6 Me 5 )]Zr(OC 6 F 5 ) 2 (NMe 2 H)       

       1 H NMR (C 6 D 6 ): δ 2.05 (s, 6H), 2.16 (s, 6H), 2.17 (s, 6H), 2.32 (s, 6H), 2.49 (s, 6H), 2.62 (m, 5H), 2.94 (s, 6H), 2.98 (m, 2H), 3.33 (m, 2H). 
       1 H NMR (C 6 D 6 ): δ 1.97 (s, 6H), 2.02 (s, 6H), 2.12 (s, 6H), 2.19 (s, 6H), 2.42 (s, 6H), 2.72 (br m, 5H), 2.92 (br m, 2H), 3.40 (br m, 2H). 
     A crystallography of the crystals was also performed. A colorless crystal of dimensions 0.32×0.38×0.45 mm was covered in the perfluoropolyether PFO-XR75 (Lancaster) and sealed under nitrogen in a glass capillary. The crystal was optically aligned on the four-circle of a Siemens P4 diffractometer equipped with a graphite monochromatic crystal, a MoKα radiation source (λ=0.71073 Å), and a SMART CCD detector held at 5.054 cm from the crystal. The sample was cooled to −50° C. with a nitrogen stream produced by a LT-2 low temperature system. Four sets of 20 frames each were collected using the ω scan method with a ten second exposure time. Integration of these frames followed by reflection indexing and least squares refinement produced a crystal orientation matrix for the triclinic lattice. 
     Data collection consisted of the measurement of a total of 1650 frames in five different runs covering a hemisphere of data. All 1650 crystallographic raw data frames were read by program SAINT (version 5/6.0) 1  and integrated using 3D profiling algorithms. The resulting data were reduced to produce a total of 27825 reflections and their intensities and estimated standard deviations. An absorption correction was applied using the SADABS routine available in SAINT. The data were corrected for Lorentz and polarization effects as well as any crystal decay. The unit cell parameters, based upon the refinement of 8512 reflections, are a=13.9403(8) Å, b=15.4456(8) Å, c=18.8204(11) Å, α=91.580(1)°, β=107.242(1)°, γ=93.358(1)°, and V=3859.3(4) Å 3 . Data preparation was carried out by using the program XPREP, 1  which gave 17246 unique reflections (R int =2.84%) with indices −17≦h≦18, −20≦k≦19, −21≦1≦24. The space group was determined to be P(−1) (No. 2). 
     The structure was solved by a combination of direct methods and Fourier methods with the use of SHELXTL6.1. There are two different molecules in the crystallographic asymmetric unit. One compound is the five-coordinate complex [(C 6 Me 5 )NCH 2 CH 2 NHCH 2 CH 2 N(C 6 Me 5 )]Zr(OC 6 F 5 ) 2  and the other is its six-coordinate dimethylamine adduct [(C 6 Me 5 )NCH 2 CH 2 NHCH 2 CH 2 N(C 6 Me 5 )]Zr(Oc 6 F 5 ) 2 (NMe 2 H). The positions for the hydrogen atoms bound to N(2), N(5), and N(7) were refined with their isotropic temperature factors set at 1.2 times that of the respective nitrogen atom. Idealized positions for the remaining hydrogen atoms were included as fixed contributions using a riding model with isotropic temperature factors set at 1.2 (aromatic protons) or 1.5 (methyl protons) times that of the adjacent carbon atom. The positions of the methyl hydrogens were optimized by a rigid rotating group refinement with idealized tetrahedral angles. Full-matrix least-squares refinement, based upon the minimization of εw i  |F o   2 −F c   2 | 2 , with w i   −1 =[σ 2  (F o   2 )+(0.0601 P) 2 +0.1887 P], where P=(Max(F o   2 , 0)+2 F c   2 )/3, converged to give final discrepancy indices of R1=0.0446, wR2=0.1157 for 12456 reflections with I&gt;2σ(I). The goodness of fit (GOF) value was 1.075. 
     A correction for secondary extinction was not applied. The maximum and minimum residual electron density peaks in the final difference Fourier map were 0.567 and −0.833 e/Å 3 , respectively. The linear absorption coefficient, atomic scattering factors and anomalous dispersion corrections were calculated from values from the International Tables for X-ray Crystallography.

General Procedure for Polymerization:
 
     A computer controlled, one liter 316 stainless steel reactor with air-operated two-wing paddle and an inner steam-heated shell and an outer water-cooled shell was dried by heating to 135° C. while purging with 500 sccm of nitrogen for 30 minutes. After cooling to 50° C., it was charged with 600 mL hexane and 43 mL 1-hexene under inert conditions. A catalyst charging vessel comprising a ¼ inch (0.64 cm)×2″ (5 cm) stainless steel tube isolated between two ball valves with a 25 mL stainless steel reservoir on top was charged with the polymerization catalyst in a drybox. A vessel atop this was charged with 5 mL dry hexane. The entire assembly was then attached to the reactor against a nitrogen purge. The reservoir containing hexane above the injection tube was pressurized to 250 psi with nitrogen. A solution of 100 micromoles of tri-isobutylaluminum (TIBA) and 2 mL 1-hexene was then added to the reactor and the reactor sealed. When the reactor reached conditions (130 psi ethylene, 85° C., 40 minutes), the catalyst was injected using the nitrogen pressure from the reservoir and held at conditions for the requisite time. The reaction was ended by venting and cooling.
