Definitions
- This invention relates to a catalyst system comprising a substituted, bridged indenyl metallocene supported on a polymeric support wherein the metallocene is activated for polymerization by an ionizing reaction and stabilized in cationic form with a noncoordinating anion.
- Propylene polymers produced by these supported catalyst systems have melting points and polymer microstructures similar to propylene polymers produced using analogous unsupported catalyst systems.
- organometallic transition metal i.e., metallocene
- organometallic transition metal cations are the chemical derivatives of organometallic transition metal compounds having both ancillary ligands which help stabilize the compound in an active electropositive state, and labile ligands at least one of which can be abstracted to render the compound cationic and at least one of which one of which is suitable for olefin insertion.
- ancillary ligands which help stabilize the compound in an active electropositive state
- labile ligands at least one of which can be abstracted to render the compound cationic and at least one of which one of which is suitable for olefin insertion.
- Technology for supporting these ionic catalysts is also known.
- U.S. Patent 5,427,991 describes the chemical bonding of noncoordinating anionic activators to supports to prepare polyanionic activators that, when used with the metallocene compounds, avoid problems of catalyst desorption experienced when ionic catalysts physically adsorbed on inert supports are utilized in solution or slurry polymerization.
- the supports are derived from inert monomeric, oligomeric, polymeric or metal oxide supports which have been modified to incorporate chemically bound, noncoordinating anions.
- the preparation of polyanionic activators from hydrocarbyl compounds entails a number of reactions.
- a typical reaction for a polymeric core component begins with use of the lithiating agent n-BuLi, or optionally lithiating a polymerizable monomers followed by polymerization of monomers into a polymeric segment to produce a polymer or cross-linked polymer having pendant hydrocarbyl lithium groups. These are subsequently treated with the bulky Lewis acid trisperfluorophenylboron (B(pfp)3) and subjected to an ion exchange reaction with dimethylanilinium hydrochloride ([DMAH] + [C1] " ) which results in a polymer surface having covalently linked activator groups of [DMAH] + [(pfb)3BP] ⁇ , where P is the polymeric core component.
- n-BuLi or optionally lithiating a polymerizable monomers followed by polymerization of monomers into a polymeric segment to produce a polymer or cross-linked polymer having pendant hydrocarbyl lithium groups.
- B(pfp)3 bulky Lewis
- An aminated polymer is prepared for example by treating a cross-linked polystyrene with a dimethyl amine. The polymer bound amine is then quarternized by ion transfer from [PhNMe H][B(C 6 F 5 ) 4 ]. The resulting support has covalently linked activator groups of [PNMe 2 H][B(C 6 F 5 ) 4 ] where P is again the polymeric core component.
- This invention relates generally to polymerization catalyst compositions comprising the reaction product of a) a polymeric support functionalized with a protonated ammonium salt of a noncoordinating anion and b) one or more substituted, bridged indenyl metallocene compounds.
- isotactic propylene polymer means a homopolymer, copolymer or terpolymer comprising at least 50% propylene units having at least 60% isotactic pentads according to analysis by 13 CNMR
- regio defect means the insertion of the monomer unit in the opposite direction relative to the prevailing insertion direction.
- stereo defect means the insertion of the monomer unit in the opposite chiral handedness as that of previously inserted units.
- Two monomer units inserted with the same handedness are said to be a meso diad.
- two monomer units inserted in the opposite handedness are said to be a racemic diad.
- N succession of meso diads constitutes an isotactic sequence.
- a succession of racemic diads constitutes a sundiotactic sequence.
- mis-insertion means insertions resulting in either regio or stereo defects.
- the invention olefin polymerization catalyst composition is the product of the reaction achieved by contacting a suitable functionalized aromatic polymeric support according to formulas I or II with one or more substituted, bridged indenyl metallocenes which are described in more detail below.
- This product is a supported ionic catalyst composition having a substituted, bridged indenyl cation and a complementary noncoordinating anion, this composition being preferably homogeneously dispersed in the polymeric support matrix.
- the functionalized aromatic polymeric supports suitable for this invention comprise a protonated ammonium salt functionality covalently bound to a polymeric support material which is preferably an aromatic polymeric support material.
- the nitrogen atom of the protonated ammonium salt functionality is substituted with one to three groups at least one of which links the ammonium functionality to the polymeric support as represented by formula I or H
- R , R 2 and R 3 in formulas I or ⁇ may be the same or different and are selected from the groups consisting of: hydrogen, hydrocarbyl, and a substituted hydrocarbyl.
- R , R 2 and R 3 contain from 1 to 30 carbon atoms, more preferably 1 to 20.
- substituted hydrocarbyl means a hydrocarbyl radical wherein one or more of the hydrogen atoms of the hydrocarbyl radical Rl, R2 and R 3 are replaced by a member of the groups selected from: halogens; a substantially hydrocarbyl group containing from 1 to 3 heteroatoms selected from the group consisting of N, O, S, and P; a hydrocarbyl substituted organometalloid; a halogen substituted organometalloid; and an organometalloid substituted with at least one substantially hydrocarbyl group containing from 1 to 3 heteroatoms selected from the group consisting of N, O, S, and P.
- NCA refers to a compatible "noncoordinating anion".
- the Rl, R2 and R- groups of the ammonium salts include those wherein two or three R groups are joined to form an alicylic or aromatic ring having a ring nitrogen atom.
- R groups include those wherein two or three R groups are joined to form an alicylic or aromatic ring having a ring nitrogen atom.
- noncoordinating anion or "NCA” means an anion which, when associated with a transition metal cation, either does not coordinate to the transition metal cation or which is only weakly coordinated to said cation thereby remaining sufficiently labile to be displaced by a neutral Lewis base under polymerization conditions.
- “Compatible” noncoordinating anions are those which are not degraded to neutrality under polymerization conditions when the complexes between them and the transition metal cationic catalyst compounds are formed. Further, the anion will not transfer an anionic substituent or fragment to the cation so as to cause it to form a neutral four coordinate metal compound and a neutral by-product from the anion under polymerization conditions.
- transition metal cation means the cation created when a ligand is abstracted from a transition metal complex.
- Noncoordinating anions most useful in accordance with this invention are those which are compatible, stabilize transition metal cation in the sense of balancing its ionic charge, yet retain sufficient lability to permit displacement by an olefinically unsaturated monomer during polymerization. Additionally, the anions most useful in this invention will be of sufficient molecular size to partially inhibit, or help to prevent, neutralization of the transition metal cation by Lewis bases other than the polymerizable monomers that may be present in the polymerization process. Suitable noncoordinating anions are described in, for example, U.S. Patents 5,198,401, 5,278,119, 5,407,884, 5,599,761, (each fully incorporated herein by reference) preferably they will be the labile proton- containing, nitrogen-based salts described in these documents.
- NCAs are those represented by the formula:
- B is boron in a valence state of 3;
- Ari and Ar are the same or different substituted-aromatic hydrocarbon radicals which radical may be linked to each other through a stable bridging group; and X 3 and X4 are independently selected from the group consisting of hydride radicals, halide radicals, hydrocarbyl radicals, substituted-hydrocarbyl radicals and orgaonometalloid radicals.
- at least one of Ari and Nr 2 are substituted with a fluoro radical, more preferably perflourophenyl radicals.
- X 3 is also a perfluorophenyl radical and t is either a perfluorophenyl radical or a straight or branched alkyl radical.
- the polymeric support comprises polymeric compound which may be any hydrocarbon based polymeric compound.
- the support is an aromatic hydrocarbon polymeric compound which has a surface area in the range of from about 1-400 m 2 /g, more preferably less than about 20 m /g and most preferably 10 m 2 /g or less so as to avoid excessive monomer access to the active catalyst sites, which sites are essentially uniformly distributed throughout the mass of the support by virtue of the randomly incorporated functional groups on the polymeric chains making up the support.
- Porosity is measured as a single point nitrogen B.E.T. (Brunauer, S.,
- the support should be insoluble under normal polymerization operating conditions.
- the support is in the form of spheres of uniform dimension having a normal size range between 100 and 400 US Mesh sizing ( 30 to 100 micrometers).
- Suitable functionalized, aromatic polymeric supports can be obtained commercially, e.g., polystyrene beads or gels, or prepared synthetically in accordance with general knowledge in the art.
- the preferred support of this invention are crosslinked polystyrene beads and gels produced by emulsion polymerization techniques. Examples of commercial products are the Advanced Polymer Systems Microsponge® and the Johns-Mannville Chromosorb®.
- Functionalized hydrocarbon polymers such as but not limited to halogenated or aminated polypropylene or polyethylene produced from metal oxide supported or metal halide supported transition metal catalysts are also possible supports.
- Support synthesis generally consists of the copolymerization of vinyl monomers with comonomers having functionalization suitable for nucleophilic substitution by ammonium salts either by direct copolymerization or by copolymerization and subsequent chemical reaction that places the appropriate functional groups according to Formulas I or II on the hydrocarbon polymeric chains making up the supports.
- a specific example is polystyrene-divinylbenzene copolymer gels or beads.
- the relative strength, i.e., resistance to fracture, is provided by the content of divinylbenzene (DVB) comonomer (weight %), commercially available products contain from 2 to 20 wt. % DVB.
- DVD divinylbenzene
- the higher ranges of DVB e.g., 10 to 20 wt.%, provide additional strength but the resulting additional crosslinking may hinder kinetics by making the bead resistant to the shrinking and swelling necessary for normal polymerization operations.
- the effective porosity is adjustable by selection of divinylbenzene content.
- DVB contents of 5 to 10 wt.% can yield restricted polymerization kinetics suitable for high activity polymerization catalysis
- DVB contents of 1 to 5 wt.% can provide less restricted polymerization kinetics suitable for lower activity polymerization catalysis.
- the term "high activity” relates to catalyst systems capable of activities greater than about 1 x 10 7 g-polymer/mol. -transition metal compound-atm-hr and "low activity” can be understood as below about that amount.
- Suitable X " groups include halide, chlorate, perchlorate, triflate, perhaloborate, perhaloantimonate.
- suitable M' + groups include alkalai metal cations and ammonium cations.
- the protonation of amines to yield ammonium salts is a technique well known in the art, simplifying the selection of H + X ⁇ .
- the product of I can be prepared in a single reaction by reacting the product of II with the ammonium salt of a compatible noncoordinating anion, R ⁇ R ⁇ R ⁇ NH + NCA".
- R4, R5 ; and R ⁇ are chosen from the same group of radicals as R*, R 2 and R 3 above, with the additional criterion that they should be chosen so as to yield an ammonium salt with a lower pK a value than that of the product of I above.
- Methods to calculate pK a are well known in the art, and experimentally measured pK a are known for a variety of amines. This provides knowledge of general guiding principles on the part of those skilled in the art (e.g., aryl substituents lower pK a relative to alkyl substituents).
- Suitable solvents include aliphatic and aromatic hydrocarbons, ethers (including cyclic ethers) and halocarbons (both aliphatic and aromatic hydrocarbons).
- the compound of II can be prepared from the direct copolymerization of the functionalized monomer with the monomeric precursors of the polymeric support. Specifically para-dimethylaminostyrene can be co-polymerized with styrene and divinylbenzene to yield the amine functionalized precursor of the invention catalyst.
- II can be prepared from a functionalized polymeric precursor of III: Polymer-Y III
- Y is a functional group known to be readily convertible to the amine functionality R!R 2 R 3 N- described above.
- suitable functional groups include but are not limited to: Alkanes, alkenes, alkyl halides, aryl halides, azides, nitro compounds, alcohols, aldehyes and ketones, nitriles, and organometalloids (for a general discussion see R. C. Larock, "Comprehensive Organic Transformations: a guide to functional group preparations", pgs. 385-438, (VCH publishers, 1989)).
- the polymeric supported activators can be readily produced in essentially pure form, i.e., as single molecular structures without any significant amount of reaction byproducts.
- Infrared spectroscopy provides a useful analytical method for monitoring the extent of the reaction to optimize reaction conditions, further assuring a high purity product.
- commercially available chloromethylated polystyrene-c ⁇ -divinylbenzene beads can be treated with a variety of dihydrocarbyl secondary amines to form weakly basic anion exchange resin, corresponding to precursor II. Reaction of these materials with dimethylanilinium tetrakis(perflurophenyl)borate yields a compound of type I, the protonated ammonium salt functionalized polymeric support.
- the reaction between the support and the metallocene should be conducted to facilitate permeation of the metallocene into the matrix of the polymeric support.
- supported activator particles are treated with a solution of the metallocene.
- Suitable solvents for the metallocene may be aliphatic or aromatic, depending upon the ligation, the chemical composition of the support material, and the degree of crosslinking of the support. Toluene and hexane are typical. It is particularly desirable to use a solvent to swell the support when it has a surface area at or below about 50 m /g.
- the reaction temperature and pressure can vary so long as the reactants, solvents and the carrier are neither degraded nor rendered unreactive. Ambient conditions are suitable.
- the resulting activation by protonation and stabilization with the noncoordinating anions is well known.
- N mixture of two or more metallocenes may be used to tailor polymer composition distribution.
- One solution containing all of the metallocenes should be made and all of the metallocenes should be completely dissolved.
- Sequential addition of metallocenes or insufficient dissolution of one or more of the metallocenes may result in a inhomogeneous distribution of active centers within the catalyst granule.
- substituted, bridged indenyl are defined to mean metallocenes, i.e.. transition metal compounds, which are consistent with the formula:
