Begin in case be aggregated on the specific transitions metal site, the part that can insert alkene normally in fact belongs to the part of growing polymer chain, its composition will be the polymeric monomer of wanting and (between part and metal) insert the initial L of end group of first olefin hydrocarbon molecules ¹This polymkeric substance part can be used group-PL ¹Represent that wherein P is divalence " polymkeric substance " (but it can have only one or several repeating unit sometimes), and is interpreted as the one or more repeating units that contain by the use monomer derived.If for example eliminate to form hydrogen root part on transition metal by β-hydride chain transfer takes place, the end group of second polymer chain will be a hydrogen.

The general formula of the transition metal complex that this paper is useful can be write as (L ¹) _x(L ²) _y(L ³) _zM (VIII), wherein L ¹And L ²As previously discussed, L ³Be (I), z is 1 or 2, and M is the transition metal of oxidation state q, and y is the integer of 1-3, and x=(q-z).L ¹And L ²Can have above-mentioned variation, and work as L ¹And L ²When being described group, transistion metal compound can intrinsicly be an active polymerizing catalyst.Table 1 has provided preferred transistion metal compound (VIII).The preferred ligand L of these compounds ³As previously discussed.

It within the implication of transition metal complex of (I) is the Lewis acid adducts of these title complexs that this paper is included in.It is meant the adducts that forms between the transition metal complex of (I) and neutral lewis acid.The structure of this adducts title complex can be described usually:

R wherein ¹, R ², R ³, n, Z, Y, M, L ¹And L ²As defined above, and LA (own) be neutral lewis acid.Preferably, metal is a 6-11 family, more preferably the late transition metal of 8-11 family.The neutral lewis acid that is fit to comprises boranes as three (pentafluorophenyl group) borane, triphenyl borane, and aluminium alkanes such as trialkyl aluminium, especially trialkylaluminium (for example triethyl aluminum) and can with other compound of transition metal complex coordinate.

More generally (also with other the part that is fit to, consult following), these title complexs that this paper is referred to as the zwitter-ion title complex especially can be used for hydrocarbon olefin (as ethene) and polar comonomers, especially the vinyl polar comonomers is (in the vinyl polar comonomers, polar group is directly connected in the vinyl carbon atom, as in the Acrylic Acid Monomer) copolymerization, especially when the title complex of the late transition metal that uses 8-11 family.Preferred metal is Pd and Ni, and Ni is particularly preferred.The neutral lewis acid that is fit to comprises three (pentafluorophenyl group) borane, the triphenyl borane, trialkyl aluminium, trialkylaluminium (for example triethyl aluminum) especially, and can with other compound of transition metal complex coordinate.Preferably, this Lewis acid should be not and any other component reaction of polymerisation catalyst system, for example do not contain can with " activity " halogen group of alkylaluminium cpd reaction, if alkylaluminium cpd is present in the polymerization process.Lewis acid is coordinated in the Lewis base that is present in the ligands for metal complexes.Therefore, can remove Lewis acid from part (metal complexes) by adding Lewis base, this Lewis base is than the stronger Lewis base of group on the part of Lewis acid institute coordination (keyed jointing).Lewis acid in this example is not meant that permanent relatively covalent linkage is connected to the Lewis acid of this part, for example-and B (aryl) ₂, wherein the boron covalent linkage is connected to the carbon atom of this part.

When using the zwitter-ion material with the formation polar comonomers, preferred hydrocarbon olefin is ethene and H ₂C=CHR ⁴, R wherein ⁴Be alkyl or substituted alkyl, preferred positive alkylidene group, and ethene is especially preferred.Preferred polar olefin is H ₂C=CHR ⁵CO ₂R ⁶, R especially wherein ⁵Be covalent linkage, and R ⁶Be alkyl or substituted hydrocarbon radical.

When the transition metal complex in zwitterionic compound was the Ni title complex, preferably, the Ni Atomic coordinate was in neutral bitooth ligand or single anion bitooth ligand.In order to use the title complex with optional intermediate metal and any part to form zwitterionic compound, this part normally contains the group that belongs to Lewis base.The combination of selected this Lewis base groups and neutral lewis acid normally has enough big difference in lewis acidity and alkalescence, so that form title complex.For example, the group that belongs to weak lewis base can form the zwitterionic compound with strong lewis acid, and vice versa.

In general, the zwitter-ion title complex can make in many ways and detect.For example, it can be used as the zwitter-ion title complex separates, and comes certification structure by the whole bag of tricks such as X-ray diffraction or various spectrum method such as NMR or Infrared spectroscopy.Its existence can also show in solution, as passing through ultraviolet, infrared or NMR spectrography.If these and other method has shown the existence of zwitterionic compound, think that so this title complex is an active polymerizing catalyst.

This paper wherein polar comonomers by any polymerization process of copolymerization in, and in any formation of any polar copolymer, preferably, the lewis acidic mol ratio of existing total polar comonomer and any interpolation is at least 2: 1, preferably at least 10: 1.Polar comonomers, as acrylic monomer in some cases by allowing they and Lewis acid react to destroy their Lewis base (or coordination) characteristic to carry out copolymerization, thereby form the Lewis acid " salt " of polar comonomers, though this usually helps to form polar copolymer, but the lewis acidic removal of stoichiometric quantity afterwards is difficult, and cost is high.

Should also be noted that, when zwitter-ion title complex during as olefin polymerization catalyst system a part of, even in hydrocarbon olefin (not having polar olefin), in the polymerization as ethene, polymerization also often is modified, as improved polymer-through-out rate and/or longer catalyst life.

In a kind of preferred form of this zwitterionic compound, the Lewis acid that is coordinated in this part in transition metal complex preferably is not that any polar group on easy and polar copolymer interacts, and especially forms to be in close proximity in the position of the polar group that carries out the atoms metal in the polymeric polymer chain.This is particularly preferred for the Ni title complex.

(by Switzerland Buchi Laboratory-Techniques, Ltd. produces the Dreiding stereoscopic model, and can obtain from Aldrich Chemical Company or other source in the U.S..The Normal Set, Aldrich classification number Z24,787-1, the Porphyrin Set, Aldrich classification number Z25,644-7 provides all required parts of this purpose in the lump) be to understand the geometric useful tool of various catalysis title complexs.They provide point-device bond length walk-off angle degree, keep the normal whole handinesies relevant with atom-atomic bond simultaneously.They have all parts and the necessary nickel of title complex, carbon, nitrogen, oxygen, phosphorus, sulphur and all other atoms that is used for being based upon in this case and is discussed.They also have the suitable scale (by dust) of measuring the distance between the former subcenter.They can be used for measuring the interactional current potential in any Lewis acid site in polar functional group on the growing polymer chain and the title complex.By the rotation of Ni-C key in the polymer chain that is bonded in the nickel center and any other C-C key, polar functional group can scan the space of a conical volume.If any available Lewis acid site (it also can rotate to this space) is arranged in this space, can there be the bonding action with this Lewis acid site in supposition so, this site will with the lone-pair electron on the nickel center balance competition polar functional group.Interactional current potential can be measured by following structure.

Initial by the square plane nickle atom, title complex makes up by two adjacent haptos that this part are incorporated into nickel.Carbon atom places the 3rd site of nickel.The 4th hapto of nickel occupied by X, and A represents part or empty hapto.

The angle θ of mode shown in solid circular cone passes through and distance (are pressed

Meter) λ and this circular cone define along the axle of nickel-carbon bond.The possible maximum value of θ is 180 °.

Being connected in the spatial circular cone volume that the polar functional group of growing polymer chain can utilize the rotation sweep of Ni-C and C-C key to go out measures by using a model.This circular cone is Lewis acid interaction circular cone or LAIC.The angle of each the additional carbon atom between nickel center and polar functional group increases.For example, under the situation of methyl acrylate, in 1 to 3 carbon atom between nickel center and carbonyl functional group, θ changes within 65 to 120 °.

They get the representative value of the LAIC that makes the important polar olefin of various industry at this paper.Have its former subcenter and can be bonded in available electron pair on polar functional group by described Lewis acid at any catalyst complexes of the Lewis acid atom within the LAIC.On the other hand, the Lewis acid in following formula in addition under θ=130 ° (and be preferred at this paper) also obviously outside LAIC, so debond is in the Lewis base electron pair of polar functional group.Want to become the preferred Lewis acid of a class of this paper, LACI should be preferably greater than about 150 ° greater than 130 °.

Also on the distance lambda at it and nickel center, be restricted by the volume that scans of rotation carbonyl.It can be not so good as just above 2

Bonding distance like that near nickel.Allowing under the maximized situation of the distance of metal center, finding that one, two and three carbon atom between nickel and the carbonyl is respectively 4.5,5.0 and 6.5

These distances have applied further restriction to lewis acidic position, but seldom become the restriction that makes up part from the distance of metal center.

When the Z in (I) was O, this part can pass through amine R ¹²NH ₂With the metal-salt of following suitable carboxylic acid, the reaction of preferred as alkali salt prepares:

R wherein ¹, R ², R ³, R ¹²With n as defined above.This reaction has obtained the part (I) as its (alkali) metal-salt.This salt can react with suitable transistion metal compound then, forms the title complex of (I) and transition metal.For example, for transition metal morning, this can simply be halogenide such as TiCl ₄Or ZrCl ₄For late transition metal complexes, it can also be halogenide such as NiBr ₂, (COD) NiBr ₂(COD is 1, the 5-cyclooctadiene) or allyl group chlorination nickel dimer.Forming in the other method of transition metal complex with late transition metal, conjugate acid (I) can be used in and makes the dialkyl group transition metal complex as (TMEDA) Ni (CH ₃) ₂(TMEDA is N, N, N ', N '-tetramethylethylened) is protonated, so that form required title complex.As mentioned above, if transistion metal compound itself is not an active polymerizing catalyst at this moment, can add suitable promotor.

When in this polymerization process, and Z is O and M when being Ni in metal complexes, and the preferred polymeric alkene of wanting comprises at least a polar olefin, is (consulting above) except the situation when described title complex further cooperates with Lewis acid.Also have when M be that Ni and Y in the transition metal complex is NR ¹²The time, preferred Z is not O.

In the polymerization process of this paper, carry out the polymeric temperature and be approximately-100 ℃ to approximately+200 ℃, preferably approximately-60 ℃ is to about 150 ℃, more preferably approximately-20 ℃ to about 100 ℃.The pressure that carries out polymeric gas alkene such as ethene is not crucial, and it is the scope that is fit to that atmosphere is pressed onto about 275MPa.Liquid olefin in fact can any concentration exist, though polymerization can be slowed down by the polar olefin of high density.

When having polar comonomers and ethene, and when in polymerisation catalyst system, using Ni title complex (yes or no zwitter-ion), preferably, polymerization process is about more than 50 ℃ or 50 ℃, more preferably 60 ℃ are arrived about 170 ℃ temperature, and carry out under the ethylene partial pressure of about at least 700kPa.More preferably, it is about 5.0MPa or more than the 5.0MPa to about 140 ℃ and/or lower ethylene pressure that this temperature range is about 80 ℃, and/or the preferred upper limit of ethylene pressure is about 200MPa, especially preferably approximately 20MPa.The polymerization process of this paper can carry out under the existence of especially non-proton organic liquid at various liquid.Catalyst system, olefinic monomer and/or polymkeric substance are solvable or insoluble in these liquid, but obviously these liquid should not hinder the polymerization generation.The liquid that is fit to comprises paraffinic hydrocarbons, naphthenic hydrocarbon, the halogenated hydrocarbons of selection, and aromatic hydrocarbons.Useful especially solvent comprises hexane, toluene, benzene, methylene dichloride, 1,2,4-trichlorobenzene and p-Xylol.

The olefinic polymerization of this paper can also be carried out with " solid-state " at first, for example by transistion metal compound being supported on substrate such as silicon-dioxide or the aluminum oxide, if necessary activating it and it is contacted with alkene with one or more promotors.In addition, carrier at first can contact (reaction) as alkylaluminium cpd with promotor (if desired), contacts with the transistion metal compound that is fit to then.If desired, this carrier can also replace Lewis acid or Bronsted acid, and for example acid clay if you would take off stone.These " heterogeneous " catalyzer can be used for the polymerization of catalyzed gas or liquid phase.So-called gas phase is meant that delivering gas alkene contacts with catalyst particle.For using the catalyst-loaded especially copolymerization of the polar olefin in liquid medium, preferred situation is when part is covalently attached to carrier, and this helps to prevent that transition metal complex from leaching from carrier.

In all polymerization processs as herein described, oligopolymer and polymkeric substance have been prepared.They from oligomeric PO (polyolefine), to lower molecular weight oil and wax, change within high molecular PO on molecular weight.A kind of preferred product has more than about 10 or 10, the PO of the polymerization degree (DP) more than the preferably approximately 40 or 40.So-called " DP " is meant the mean value of the repeating unit in the PO molecule.

The performance that depends on them, the PO for preparing by method as herein described can use in many ways.For example, if they are thermoplastic, they can be used as moulding resin, are used to extrude, and are used as film etc.If they are elastic, they can be used as elastomerics and use.If they contain functionalized monomer such as acrylate, they can be used for other purpose, for example consult the US 5880241 that introduces previously.

It is believed that the catalyzer that contains late transition metal (as Ni) used herein has usually obtained to have the polymkeric substance of unusual branched pattern, for example consult people such as the US 5880241 that introduces previously and Z.Guan , Science, 283 volumes, 2059-2062 page or leaf (1999).On the other hand, the catalyzer that contains transition metal morning (as Ti and Zr) has obtained to have more common branched polymers usually, those as preparing by Z-N or metallocenes polymerizing catalyst.

Depend on employed processing condition and selected polymerisation catalyst system, PO can have different performances.Some performances that can change are molecular weight and molecular weight distribution, degree of crystallinity, fusing point and second-order transition temperature.Except molecular weight and molecular weight distribution, branching can influence all mentioned other performances, and branching can (be used identical nickel compound) and uses the method described in the US 5880241 quote in front to change.

Be known that and " single " polymer phase ratio that for example the blend of vicissitudinous different polymkeric substance can have favourable performance on the above performance of enumerating.For example, be known that the polymkeric substance with wide or bimodal molecular weight distribution can the easier melt (moulding) of carrying out of narrow molecular weight distribution polymer.Thermoplastics such as crystalline polymer can be usually by toughening with the elastomer polymer blend.

Therefore, the method that produces the production polymkeric substance of blend polymer inherently is useful especially, if can save the mixed with polymers step of (and expensive) separately afterwards.Yet in this polymerization, people should be clear, and two kinds of different catalyzer can interfere with each other, and perhaps interacts in a kind of like this mode that obtains single polymers.

In this method, the polymerizing catalyst that contains transition metal disclosed herein can be called as first active polymerizing catalyst.Second active polymerizing catalyst (with one or more optional other catalyzer) is united use with first active polymerizing catalyst.Second active polymerizing catalyst can be as at the US 5880241 that for example quotes previously, and US 6060569, and US6174795 and S.D.Ittel wait the people, Chem.Rev., 100 volumes, 1169-1203 page or leaf (2000) (document of quoting with this paper), and US 5714556 and US 5955555 (they also at this paper as with reference to introducing, seem to describe fully at this paper) described in another late transition metal catalyzer.The catalyzer that can also use other useful type is as second active polymerizing catalyst.For example, can also use so-called Z-N and/or class of metallocenes catalyzer.The catalyzer of these types is known in polyolefin field, for example consults about the information of class of metallocenes catalyzer Angew.Chem., Int.Ed.Engl., 34 volumes, 1143-1170 (1995), EP-A-0416815 and US 5198401, and consult J.Boor Jr. about the information of ziegler-natta type catalyzer, Ziegler-Natta Catalysts and Polymerizations, Academic Press, New York, 1979, all these are introduced as reference at this paper.The catalyzer of all these types of confession and the many useful polymerizing condition that first active polymerizing catalyst is used are consistent, so reach easily with the polymeric condition of first and second active polymerizing catalysts.Usually, metallocenes and ziegler-natta type polymerization need " promotor " or " activator ".In many examples, identical compound can be as some or all " activator " of the various polymerizing catalysts of this paper as alkylaluminium cpd.

In a kind of preferable methods of this paper narration, first alkene (by the first active polymerizing catalyst polymeric alkene) is identical with second alkene (by the second active polymerizing catalyst polymeric monomer).Second alkene can also be the mixture of the alkene of single alkene or preparation multipolymer.

In the certain methods of this paper, first active polymerizing catalyst is by one or more alkene, can be not by the described second active polymerizing catalyst polymeric monomer polymerization, and/or vice versa.In this case, can produce two kinds of polymkeric substance that chemical property is different.In another program, will there be two kinds of monomers, wherein a kind of polymerizing catalyst produces multipolymer and another kind of polymerizing catalyst produces homopolymer.

Equally, these polymeric conditions of the catalyzer of the second living polymerization class in suitable above-mentioned reference, have also been found to use.

In this polymerization process, use two kinds of active polymerizing catalysts that chemical property is different.At above first active polymerizing catalyst that has been described in detail.Second active polymerizing catalyst can also satisfy the restriction of first active polymerizing catalyst, but must be that chemical property is different.For example, it can utilize the discrepant different ligands of structure between first and second active polymerizing catalysts.In a kind of preferable methods, the part type is identical with metal, but the substituting group difference of part.

Be included within the definition of two kinds of active polymerizing catalysts is wherein single polymerizing catalyst and another part, the system that the part of preferred same type adds together, this part can be replaced the initial part of the metal that is coordinated in the initial activity polymerizing catalyst, so that produce two kinds of different polymerizing catalysts on the spot.

The mol ratio of employed first active polymerizing catalyst and second active polymerizing catalyst will depend on desirable polymer ratio from each catalyzer, and each catalyzer polymeric relative rate under processing condition.For example, if people want preparation to contain 80% crystalline polyethylene and 20% rubber-like poly " toughness reinforcing " thermoplastic polyethylene, and the polymerization velocity of two kinds of catalyzer equates, will use the catalyzer and generation rubber-like catalyst of polyethylene of 4: 1 generation crystalline polyethylene of mol ratio so.If want required product to contain the polymkeric substance of two or more types, can also use two or more active polymerizing catalysts.

Polymkeric substance by first active polymerizing catalyst and the preparation of second active polymerizing catalyst can prepare according to the order of sequence,, earlier with a kind of catalyzer (first or second) polymerization, then uses another kind of polymerization catalyst that is, as passing through to use placed in-line two polymerization reactors.Yet, preferably use first and second active polymerizing catalysts in identical reactor, promptly carry out polymerization simultaneously.This is feasible, because in most of the cases, first and second active polymerizing catalysts are compatible with each other, and they have produced their different polymkeric substance in the presence of another kind of catalyzer.In having this polymerization process of two or more catalyzer, can use any method that is applicable to indivedual catalyzer, i.e. gas phase, liquid phase, method such as continuous.

The polymkeric substance of producing by this method can be in molecular weight and/or molecular weight distribution and/or fusing point and/or degree of crystallinity, and/or change on second-order transition temperature and/or the other factors.The polymkeric substance of being produced can be used as molding and extrusion resin, and as film for packaging.They can have such as improved melt, the advantage of toughness and improved low-temperature performance and so on.

This paper also discloses the transition metal complex that comprises (I), is with or without the catalyst component of other material such as one or more promotors and/or other polymerizing catalyst.For example, this catalyst component can comprise the Ni title complex that is supported on carrier such as aluminum oxide, silicon-dioxide, polymkeric substance, magnesium chloride, the sodium-chlor etc., is with or without other component and exists.It can simply be the solution of this title complex, or the slurry of this title complex in liquid, is with or without carrier and exists.

Can use hydrogen or other chain-transfer agent such as silane (for example trimethyl silane or triethyl silicane) to be reduced in the polyolefinic molecular weight of producing in the polymerization process of this paper.Preferably, the hydrogen amount is about 0.01 to about 50mol% of an alkene amount, preferably approximately 1 to about 20mol%.The relative concentration of gas alkene such as ethene and hydrogen can be regulated by the relative dividing potential drop that changes them.
