Description

The branched block ethylene polymers thing, its preparation method and the composition that comprises it
The field of the invention
The present invention relates to ethene polymers, more particularly polyvinyl block polymer contains the composition of block ethylene polymers thing, prepares the method for this block ethylene polymers thing and the method for compositions that preparation contains this block ethylene polymers thing.
Background of the present invention
Polyvinyl graft modification with various ethylenically unsaturated monomers is well-known in the prior art.This class modification makes that the non-polar polymer material is compatible on limited degree at least with polar material basically.
Yet graft modification has infringement to polyvinyl one or more other performances.For example, USP4,134,927,3,884,882 and 5,140,074 has all reported the crosslinked rheological property that changed because of the graft modification material.These change the processibility of finally having damaged material, have therefore influenced its prospects for commercial application.
Also have, when hope during with ethene polymers and another kind of molded polymeric blend, polyvinyl graft modification (having the binding property of benefiting) can influence that ethene polymers is used with together or the consistency of molding usefulness polymkeric substance.If ethene polymers can be with a kind of mode modification as follows then is ideal: the consistency of other polymkeric substance can not be affected and other performance such as the rheological property of ethene polymers (with preferred resulting blend) are improved simultaneously in ethene polymers and the blend.
The industrial other and special challenge that faces is the improvement of the performance of polycarbonate.This shortcoming what by polycarbonate and various olefin polymer such as new LDPE (film grade) or linear low density polyethylene, or the practice that thermoplastic elastomer such as ethylene/propene copolymer carry out blend has alleviated.The material of these interpolations can improve the tolerance of polycarbonate to solvent, but they trend towards leafing and cause by the reduction in various degree of the toughness of the polycarbonate compositions of blend, shock resistance and weld line strength.The loss of this type of leafing and purposes for example is reported in US-A-4, in 496,693.
The shock resistance of polycarbonate can be improved by introducing emulsion or nuclear-shell elastomer such as methacrylic ester/butadiene/styrene copolymers or butyl acrylate cores rubber.Yet these nuclears-shell rubber impairs processibility because of improving viscosity, and the solvent resistance of polycarbonate is not had improvement.If can not influence toughness and shock strength and weld line strength with the properties-correcting agent that the improves solvent resistance properties-correcting agent of alkene (especially based on) with thermoplastics such as polycarbonate blending, can not cause leafing (by peeling off or cracked proof the in the moulded product), will be ideal.

Of the present invention being described in detail
Branched block ethylene polymers thing of the present invention prepares from following component: (i) ethene polymers, preferably have be lower than by the defined Mw/Mn of gel permeation chromatography about 3.0, more preferably homogeneous ethene polymers; The (ii) unsaturated functionalized organic compound of olefinic; (iii) can with the reactive behavior thermoplastic polymer of the unsaturated functionalized organic compound reaction of olefinic.Ethene polymers is considered to first kind of polymer blocks.The unsaturated functionalized organic compound of olefinic is by forming branched ethylene polymer on its pair key addition ethene polymers.If the branch that is formed by the unsaturated functionalized organic compound of olefinic has enough length (for example containing 3 or more a plurality of molecule), we can say that it has formed second block of itself.Yet this branch is only formed by a unsaturated functionalized organic compound molecule of olefinic.Irrelevant with the ramose length that is formed by the unsaturated functionalized organic compound of olefinic, branched ethylene polymer is by functional group on the residue of the unsaturated functionalized organic compound of olefinic and the final polymer blocks of reactive behavior thermoplastic polymer reaction formation.
Tapping point (contain the residue of one or more molecules of the unsaturated functionalized organic compound of olefinic and keyed jointing reactive behavior thermoplastic polymer as final polymer blocks) is different from long-chain and short-chain branched, and this branching is to occur on the ethene polymers preparing the ethene polymers process from ethene and (non-essential) another kind of monomer such as alpha-olefin.The skeleton formed branch of growing is opposite with following in the ethylene polymerization process, and the tapping point that forms from the unsaturated functionalized organic compound of olefinic is added its initial polymerization after, and to be incorporated on the ethene polymers and to provide be the final polymer blocks needed reaction active site of keyed jointing reactive behavior thermoplastic polymer as the branched block ethylene polymers thing.
About subfraction (a)-ethene polymers
Subfraction (a) is the ethene polymers that forms first block in the preparation of branched block ethylene polymers thing of the present invention.The ethene polymers that is used for this purpose comprises, conventional ethene polymers such as new LDPE (film grade) (" LDPE "), linear low density polyethylene (" LLDPE "), and high density polyethylene(HDPE) (" HDPE ").That LDPE typically is considered to be under the condition of high voltage preparation and have an about 0.935g/cm of about 0.915- 3Density.This low density is that the many zones by amorphous arrangement cause, and it is the feature of LDPE, owing to its long chain branches, and the length that many branches are the same with skeleton.As long as the density of pure amorphous polyethylene is 0.855g/cm 3, be 0.97g/cm with having density 3The contrast of pure crystalline polypropylene, can find that LDPE has some crystallizations.Yet its long chain branching is a principal character.Typically per 1000 carbon atoms of LDPE have 4-25 and sometimes up to 90 these type of long chain branches.It also has 10-35 short chain/per 1000 carbon atoms, each short chain contains 2-8 carbon atom, this is sting (backbiting) and molecule and caused along the rearrangement of skeleton by returning in the chain growth process, is not caused by the comonomer introducing the LLDPE and do not resemble.
Can prepare LDPE in tubular reactor or stirring tank, when when heating, the pressurization feedstream of ethylene gas, radical initiator and optional chain-transfer agent is injected in the reaction unit.Form reaction usually 1,500-3,000atm (152-304MPa) and carry out being no more than under 300 ℃ the temperature, this is known in the prior art.In the polymerization process of LDPE, ethene and other monomer such as vinyl-acetic ester, ethyl propenoate, vinylformic acid, vinylchlorid or carbon monoxide carry out copolymerization.
Usually be considered to form LLDPE for preparing under that suitable similar low pressure condition of HDPE.Yet, obtain low density product (0.910-0.940g/cm 3), because, not to form homopolymer, ethene and one or more alpha-olefin copolymers close, and they take short-side chain form and function in final product.Because the most frequently used comonomer is alpha-olefin such as 1-butylene, 4-methyl-1-pentene, 1-hexene or 1-octene, these side chains prevent tight, the accumulation of crystallization type fully of HDPE, but they are not too near, as long as make under condition of high voltage and the complete branching of LDPE bonded, long side chain.LLDPE can form slurry by using the carrying chrome catalysts in light hydrocarbon diluent, or by using organo-metallic-titanium type catalyzer in hexane, to form slurry.It can also form solution in suitable hydrocarbons under about 250 ℃, or it can form in gas phase, as Levine at USP4, described in 011,382, or as Jezl at USP4, described in 129,729.
About typically 94% crystallization of HDPE homopolymer or multipolymer also has density for about 0.935g/cm 3More than, especially be about 0.950-0.970g/cm 3HDPE because other higher degree of crystallinity and density, has higher fusing point-135 ℃ to 115 ℃ than LDPE.Crystallization HDPE homopolymer has the linearity of rule and typically forms a kind of ordered set aggressiveness that is known as crystal grain in the back that is cooled, so HDPE has obtained excellent toughness and shatter-proof fragility.If ethene and alpha-olefin copolymer close, as mentioned above, if or by concrete reaction mechanism specific side reaction causes short-chain branchedly, then will disturb crystallization and density in HDPE correspondingly to descend.For example, the HDPE with the preparation of Ziegler transition-metal catalyst has about 0.5-4 short chain branch (especially methyl)/per 1000 carbon atoms.The molecular weight of HDPE is usually 50, and 000-1 is in 000,000 scope or higher.The molecular weight that exceeds specified point raising HDPE is in fact because chain entanglement causes the decline of density, but influence is not too obvious.Overwhelming majority situation, HDPE intensity descends with the decline of molecular weight.HDPE can prepare in slurry system, and wherein high-purity ethylene is added into to contain and is used for dissolve ethylene and making in the annular reactor of the low boiling hydrocarbon that catalyzer and polymer beads suspend.In addition, HDPE can prepare in gas phase process, does not wherein use hydrocarbon diluent and fluidized-bed to be used for stirring and suspended polymer particles.The method of making HDPE is described in the USP2 of Hogan particularly, in 825,721.
About the purposes of homogeneous ethene polymers as subfraction (a)
Preferably, subfraction (a) is the homogeneous ethene polymers.Being characterized as of homogeneous polymers has narrow polymolecularity (Mw/Mn) and uniform short-chain branched distribution.The polyvinyl polymolecularity of homogeneous as described herein (Mw/Mn) can be determined from the data that obtained by gel permeation chromatography (GPC).It is 150 ℃ of high temperature chromatogram arrangements of Waters that the typical case is used for this purpose instrument, and three porousness mixed bed columns (Polymer Laboratories 103,104,105 and 106) are housed, in 140 ℃ of operations down of system temperature.Employed solvent is 1,2, the 4-trichlorobenzene, and the 0.3wt% solution of preparation sample is with injection.Flow velocity is that 1.0 ml/min and injection volume are 200 microlitres.
Poly molecular weight determination is that the polystyrene standard (available from Polymer Laboratories) by using narrow molecular weight distributions is carried out together with their elution volume.Measure the equivalent molecular weight of polyethylene by the suitable mark Hao Wenke coefficient that uses polyethylene and polystyrene, as Williams and Word at the polymer science periodical, Polymer Letter, 6 volumes, 621 pages, nineteen sixty-eight (it is for reference to be introduced into this paper) is described, the following equation of computing:
M Polyethylene=a* (M Polystyrene) bA=0.4316 wherein, b=1.0 and M be polyethylene and polystyrene 1,2, the molecular weight in the 4-trichlorobenzene.Weight-average molecular weight Mw calculates in the usual way according to following relational expression: Mw=∑ wi*Mi, wherein wi and Mi are respectively the weight fraction and the molecular weight of the i fraction that wash-out goes out from the GPC post.Number-average molecular weight Mn calculates in the usual way according to following relational expression: Mn=[∑ ni*Mi]/∑ ni, wherein ni and Mi are respectively the molecule number and the molecular weight of the i fraction that wash-out goes out from the GPC post.Symbol * represents a step multiplication.
The polyvinyl polymolecularity of described homogeneous (Mw/Mn) be lower than about 3.0, preferably about 1.5-about 2.5 and more preferably from about 1.7-is about 2.3, most preferably from about 2.
When they are ethylene/alpha-olefin copolymer, the homogeneous ethene polymers will have uniform branching and distribute.Term " evenly branching " and " evenly branching distributes " are meant that (1) alpha-olefin comonomer is the given intramolecularly random distribution at ethene/comonomer multipolymer; (2) all basically copolymer molecules have same ethene/comonomer ratio; (3) polymkeric substance is characterised in that narrow short-chain branched distribution; (4) polymkeric substance does not have measurable high-density, crystalline polymer fraction [for example by comprise polymkeric substance classification wash-out measure as those technology of temperature function] substantially; (5) feature of polymkeric substance, press 21C.F.R.177.1520 (c) and (d) in the condition described measure, be the positive hexanaphthene extraction quantity that has (i) but significantly reduce (for example ethene/1-octene copolymer be higher than be lower than 1% extractable matter under the density of about 0.90g/cc), or (ii) tangible amorphism, by when the polymkeric substance that is higher than 75wt% is solvable under prescribed condition, showing that (for example, ethene/1-octene copolymer is at about 0.90g/cm 3Be 90% solvable and be 100% solvable under the density of about 0.88g/cm under the density).
Typically, the homogeneous ethene polymers has even short-chain branched distribution and does not have any measurable high-density fraction, be that these polymkeric substance do not contain by USP5, the degree of branching that " the temperature rising elution fractionation method " described in 089,321 measured is less than or equal to any polymer fractions of 2 methyl/1000 carbon atoms.
Homogeneity or narrow degree that branching distributes are further represented by the value of forming distribution branch index (" CDBI ") or short chain branch dispersion index (" SCBDI ").CDBI is defined as having the weight percentage (wt%) of the polymer molecule of co-monomer content in average total mole co-monomer content of 50%.The CDBI of polymkeric substance is for example easily by using as the polymer science periodical of Wild, the polymer physics version, 20 roll up, 441 pages, nineteen eighty-two and in US patent 4,798,081 (it is for reference to be introduced into this paper) described temperature rising elution fractionation calculate.The CDBI of the homogeneous ethylene/alpha-olefin copolymer of Shi Yonging is higher than approximately 30% in the present invention, preferably is higher than about 50% and more preferably be higher than about 80% and most preferably be higher than about 90%.
The homogeneous ethene polymers does not comprise from its definition: the inhomogeneous branching linear low density polyethylene or the linear high-density polyethylene that use Ziegler-Natta polymerization method (for example, pressing the USP4 of Anderson, described in 076,698) to make; Or the high pressure of branching, radical polymerization polyethylene and other high-pressure ethylene multipolymer (for example, Ethylene/vinyl acetate or ethylene/vinyl base alcohol copolymer), known for skilled person of the prior art have a large amount of long chain branches.
For the homogeneous ethene polymers in the ethylene/alpha-olefin copolymer, it has a unique melting hump, and (DSC) records between 30 ℃ and 150 ℃ by dsc.This linear tetrafluoroethylene polymer with the inhomogeneous branching of Ziegler process polymeric is opposite, and the latter is owing to their wide branching distribution has 2 or a plurality of melting hump.Yet, have an about 0.875g/cm of density for some class 3With about 0.91g/cm 3The homogeneous ethene polymers, single melting hump will demonstrate (depending on the device susceptibility) " shoulder " or " hump " on the downside (promptly being lower than fusing point) of melting hump, they account for below 12% of the total melting heat of polymkeric substance, typically are lower than 9%, more typically are lower than 6%.This phenomenon changes owing to chain in the polymkeric substance and it is that the basis is differentiated with gradient monotone variation in the whole melting area of this phenomenon of single melting hump.This phenomenon takes place in 34 ℃ of the fusing point of single melting hump, typically in 27 ℃ and more typically in 20 ℃.
Use the single melting hump of determine with dsc method with indium and deionized water calibration.This method comprises the sample of about 5 7mg sizes, " heating for the first time " was to about 150 ℃ of maintenances 4 minutes, be cooled to 30 ℃ with 10 ℃/minute speed and kept 3 minutes and be heated to 150 ℃, draw " heating for the second time " hot-fluid/temperature curve with 10 ℃/minute speed.Area below curve calculates total melting heat of polymkeric substance.The melting heat (if existence) that is attributable to above-mentioned phenomenon can be calculated by operational analysis balance and weight percentage and measure.
A kind of homogeneous ethene polymers of known type is " a homogeneous linear tetrafluoroethylene polymer ".The homogeneous ethene polymers does not have long chain branching, as following definition.Term " linearity " is not meant body high pressure branched polyethylene, and ethylene, or ethylene/vinyl alcohol copolymer have many long chain branches because the polymkeric substance of these types is known the skilled person in prior art.
The homogeneous linear tetrafluoroethylene polymer is from the polymkeric substance of known type, its example is included in USP3,645, described in 992 those, by use in having the batch reactor of higher ethylene concentration that so-called single position (single site) catalyzer makes those [as US patent 5,026,798 (Canich) or US patent 5,055, described in 438 (Canich)] and by use in having the batch reactor of higher concentration of olefin also that the constrained geometry catalyzer makes those [as US patent 5,064,802 (Stevens) or EP-A-416 are described in 815 (Stevens)].There is not long chain branching in these polymkeric substance, as by Van der Sanden and Halle at TappiJournal, described in 1992 2 months.The method of using metalloscene catalyst to produce the homogeneous linear tetrafluoroethylene polymer has been developed much, for example, sees Ewen in USP4,937,299, EP129,368, EP260,999, USP4,701,432, USP4,937,301, USP4,935,397, USP5,055,438 and WO90/07526, it is for reference that each part document is introduced into this paper.This base polymer can make by polymerization process such as gas phase, slurry or the solution methods of routine.
Preferably, the homogeneous ethene polymers of known type is that " ethene polymers of substantial linear " and embodiment are characterized as required processibility level, for example to the Wheat Protein of melt fracture, even under the shearing force condition.The ethene polymers of substantial linear has the critical shear rate when surperficial melt fracture begins and has a kind of processing index, they be significantly higher than respectively and significantly be lower than same molecular weight distribution and melt index lower linear poly those.The ethene polymers of substantial linear have the shear shinning behavior and with the similar workability of highly branched new LDPE (film grade) (LDPE), and have the intensity and the toughness of linear low density polyethylene (LLDPE).The ethene polymers of substantial linear described herein and make their method also is described in US patent 5,272,236, US5,278,272 and US.SN 08/301,948.
Here employed " ethene polymers of substantial linear " is meant, except introducing the short-chain branched distribution that is caused because of any comonomer, polymkeric substance is further characterized in that to have long chain branches.The ethene polymers of substantial linear embodies to be characterized as to have and is greater than or equal to 5.63 melt flow and compares I 10/ I 2, be less than or equal to I 10/ I 2-4.63 molecular weight distribution (by gel permeation chromatography) Mw/Mn and have certain critical shear rate when surperficial melt fracture begins, this speed ratio has roughly the same I 2High at least by 50% with Mw/Mn and/or the critical shearing stress that when surperficial melt fracture begins, had, or be higher than about 2.8 * 10 6Dynes per centimeter 2Critical shear rate.
According to Ramamurthy at the rheology periodical, 30 (2), 337-357 described in 1986, is higher than some critical flow speed, and surperficial melt fracture can take place, and causes the more irregularity of severe form " shark skin " that is lost to from specular gloss.Here employed, " beginning of surperficial melt fracture " embodiment is characterized as loss extrudate glossy and begins, and the surface irregularity performance of extrudate is enough only detected by 40 * magnifying glass at this moment.The ethene polymers of substantial linear will further embody and be characterized as: critical shear rate is than having about identical I when the beginning of surperficial melt fracture 2With the linear tetrafluoroethylene polymer of the Mw/Mn critical shear rate high at least 50% when the beginning of surperficial melt fracture.Apparent shear-stress/apparent shear rate curve is used for by using mouthful mould or gas squeezing rheometer (gas extrusion rheometer-GER) to verify the melt fracture phenomenon in the nitrogen pressure scope of 5250-500psig; according to people such as Shida in Polymer Engineering Science (polymer engineering science); 17 volumes; No; 11 (1977) and at the Rheometers of John Dealy for Molten Plastics (rheological analysis of molten plastic); described in the Van Nostrand Reinhold Co. (1982), 97-99 page or leaf like that.According to Ramamurthy at the rheology periodical, 30 (2), 337-357 described in 1986, is higher than some critical flow velocity, the irregularity of viewed extrudate can loosely be divided into two kinds of main types: surperficial melt fracture and overall melt fracture.
Surperficial melt fracture takes place under apparent steady flow condition, is in the scope that is lost to severe form " shark skin " more of specular gloss in detail.In this publication, " beginning of surperficial melt fracture " embodies the beginning that is characterized as the loss of extrudate glossy, and the surface irregularity of extrudate is only detected by 40 * magnifying glass at this moment.The critical shear rate of the ethene polymers of substantial linear when surperficial melt fracture begins is than the critical shear rate height at least 50% of common linear tetrafluoroethylene polymer when surperficial melt fracture begins, I for them 2, polymolecularity and density are equivalent to the 90-110% of the polyvinyl analog value of substantial linear separately.Preferably, the critical shearing stress of the ethene polymers of substantial linear when surperficial melt fracture begins is higher than about 2.8 * 10 6Dynes per centimeter 2
Overall melt fracture can take place under instability flows condition and be in detail from regular surfaces distortion (as the rough and smooth alternately, or spiral pattern) in the scope of random distortion.For coml acceptability (for example with regard to the blown film goods),, should be minimum if surface imperfection exists.Critical shear rate and critical shearing stress when overall melt fracture begins (OGMF) are with relevant by the variation of the surfaceness of the extrudate of GER production and configuration when surperficial melt fracture begins (OSMF).For the ethene polymers of substantial linear described herein, critical shearing stress preferably is higher than about 4 * 10 when overall melt fracture begins 6Dynes per centimeter 2
Measure and measure for the GER melt fracture for following described processing index (PI), do not have mineral filler and 20ppm is arranged or the situation of lower Al catalysts residue under the ethene polymers of test substantial linear.Measure for these, polymkeric substance preferably contains antioxidant, as phenols, and Hinered phenols, phosphorous acid esters or phosphinate, the mixture of phenols or Hinered phenols and phosphorous acid ester or phosphinate when preferred.
Other indication of the polyvinyl improvement processibility of substantial linear is rheology processing index (PI).PI is the apparent viscosity (thousand pools) of polymkeric substance, and extrudes rheological analysis (GER) by gas and measure.More than GER is described with the mensuration of melt fracture phenomenon.Under nitrogen pressure 2500psig, measure processing index in 190 ℃.(for example has I for the high workability polymkeric substance 2Be 50-100g/10min or higher polymkeric substance), using diameter is 0.0296 inch (752 microns), preferred 0.0143 inch, having 20: 1 length/diameter ratios and having input angle is 180 ℃ mouth mould.
Processing index calculates with millipoise unit from following equation:
PI=2.15 * 10 6Dynes per centimeter 2/ (1000 * shearing rate)
Wherein 2.15 * 10 6Dynes per centimeter 2Be that shear-stress under 2500psi and shearing rate are the shearing rates on wall, represent by following equation:
32Q '/(60 seconds/minute) (0.745) (diameter * 2.54 centimetre/inch) 3Wherein Q ' is rate of extrusion (g/min), the 0.745th, and poly fusant density (g/cm 3); With diameter be kapillary opening diameter (inch).PI is 2.15 * 10 6Dynes per centimeter 2The apparent viscosity of the material measured down of apparent shear-stress.
For the ethene polymers of substantial linear, PI be less than or equal to common linear tetrafluoroethylene polymer PI 70%, I for them 2, polymolecularity and density are equivalent to the 90-110% of the polyvinyl analog value of substantial linear separately.
The ethene polymers of substantial linear has improved melt elasticity or melt tension, with the homogeneous linear tetrafluoroethylene polymer Comparatively speaking.By specially specified pulley transverter and melt index apparatus are measured " melt tension ".Melt tension be extrudate or wire drawing above pulley by arrive two inches with the rotary drum of 30rpm rotating speed rotation in by extrudate or load that wire drawing was applied.It is similar that melt tension is measured the method for being carried out with " the melt tension tester " made by Toyoseiki, and by John Dealy in Rheometers for MoltenPlastics (rheological analysis of molten plastic), Van Nostrand Reinhold Co. (1982) is described in the 250-251 page or leaf.The polyvinyl melt tension of substantial linear described herein is at least about 2 grams, with especially for having narrow molecular weight distributions those of 1.5-2.5 according to appointment, melt tension is typically at least about 5%, and can be up to about 60%, the melt tension that is higher than common linear ethylene copolymer, the melt index of this multipolymer, polymolecularity and density are equivalent to the 90-110% of the polyvinyl analog value of substantial linear separately.
Polyvinyl other unique property of these substantial linear is a flowing property, and it causes I 10/ I 2Value is irrelevant with polymolecularity (Mw/Mn) basically.This obviously is different from common Ziegler polymeric homogeneous ethene polymers and is different from the homogeneous polyvinyl resin of common single position polymerization catalyst, and its rheological property should make along with the raising of polymolecularity (Mw/Mn), I 10/ I 2Value also can improve.Should be noted that, unnecessaryly in the ethene polymers of substantial linear, add superoxide, in order that make polymkeric substance demonstrate the I that has nothing to do with polymolecularity (Mw/Mn) and melt fracture performance 10/ I 2Value.
In general, the polyvinyl I of substantial linear 10/ I 2Than being at least about 5.63, preferably at least about 7, in the time of especially at least about 8 with most preferably be at least about more than 9 or 9.To the highest I 10/ I 2Unique qualification of ratio is a factor of putting into practice the aspect, as economic cause or kinetics of polymerization reaction, but the highest I typically 10/ I 2Than can and preferably not being no more than about 15 above about 20.On the contrary, the I of homogeneous linear tetrafluoroethylene polymer described herein 10/ I 2Than generally is below 6 or 6.
It is believed that the polyvinyl desirable melt elasticity of substantial linear and processibility are to obtain from their production method.Can produce polymkeric substance by means of (with intermittently opposite) continuously controlled fusion method of using at least one reactor, for example according to WO93/07187, the method for describing among WO93/07188 and the WO93/07189.Yet these polymkeric substance also can for example use many reactors by the multiple reaction device that uses as describe in US patent 3,914,342, produce under polymerization temperature that is enough to produce the multipolymer with desired properties and pressure.
The polyvinyl polymerizing condition of making substantial linear generally is those conditions that can be used for solution polymerization process, though slurry and gas phase polymerization process also are operable, as long as use appropriate catalyst and polymerizing condition.Multiple reaction device polymerization process also can be used for this purpose, as at US3, and those described in 914,342.The multiple reaction device can serial or parallel connection operation, at least one of reactor, use at least a constrained geometry catalyzer.
Carry out the successive polymerization reaction ideally under the condition well known in the prior art of Z-N or Kaminsky-Sinn type polyreaction, for example the about 0-250 of temperature ℃ is normal pressure-1000 normal atmosphere (100MPa) with pressure.Can use carrier, but preferably catalyzer uses in even (promptly soluble) mode.Certainly, will recognize that,, comprise the monomer of condensation, then form active catalyst system on the spot if catalyzer and its cocatalyst component are introduced directly in the polymerization process and use suitable solvent or thinner.Yet, preferably before joining catalyzer in the polyblend, in suitable solvent, in an independent step, form active catalyst.
Preferably, term " ethene polymers of substantial linear " expression mass polymer is on average replaced by about 0.01 long chain branches/1000 total carbon atom (comprising skeleton and branch's carbon atom)-Yue 3 long chain branches/1000 total carbon atoms.Preferred polymkeric substance is by about 0.01 long chain branches/1000 total carbon atom-1 long chain branches/1000 total carbon atoms, more preferably from about 0.05 long chain branches/1000 total carbon atom-1 long chain branches/1000 total carbon atom and about 0.3 long chain branches/1000 total carbon atom-1 long chain branches/1000 total carbon atoms replace.
Here employed term " skeleton " is meant individual molecule and term " polymer " " " mass polymer " say by common meaning and be meant the polymkeric substance that forms in reactor.Term " body " polymkeric substance is meant the polymkeric substance that obtains from polymerization process, and, for the ethene polymers of these substantial linear, comprise molecule that does not have long chain branching and molecule with long chain branching.Therefore, " body " polymkeric substance is included in all molecules that form in the polymerization process.Ethene polymers for substantial linear, it should be understood that not every molecule has long chain branching, but the long chain branching of q.s is arranged so that the average long chain branching group content of mass polymer can advantageously influence the melt rheological property energy (that is melt fracture performance) of mass polymer.If polymkeric substance is as if the ethene polymers of " substantial linear ", this polymkeric substance must have enough at least molecules that long chain branching is arranged, so that average long chain branching rate is average at least about 0.01/1000 total carbon atom in the mass polymer.
When the ethene polymers of the substantial linear that contains long chain branching was ethylene/alpha-olefin copolymer, long chain branches can have the chain length of hanging down a carbon atom at least than carbonatoms in the comonomer.On the contrary, short chain branch is defined in the chain length that has same carbon atoms number on the residue that comonomer is introduced on the polymer molecule skeleton back and this comonomer.For example, ethene/1-octene sex ethylene polymkeric substance of reaching the standard grade substantially has the skeleton of the long chain branches that has at least 7 carbon atoms of length, and has the only short chain branch of 6 carbon atoms of length.
For ethylene/alpha-olefin copolymer, long chain branches is longer than short chain branch, and this causes owing to alpha-olefin is incorporated on the polymer backbone.The experience effect of the existence in the employed in the present invention substantial linear ethylene/alpha-olefin copolymer of long chain branching can be shown that this performance is extruded rheological analysis (GER) result and/or fluidity of molten I according to gas by the enhanced rheological property 10/ I 2Improve and come quantitatively and expression, as mentioned above.
By using 13C nuclear magnetic resonance spectrum (NMR) is distinguished long chain branching and short-chain branched, and for Alathon with for ethene and C 2-C 6The multipolymer of alkene, it can be by using the polymer science bulletin periodical of Randall in Polymer Chemistry and Physics, and C29 rolls up, and the method in the 285-297 page or leaf (1989) is come quantitatively.Yet the long chain branches part that in fact surpasses six carbon atom can not use present being used for to measure the exact length of long chain branches 13C NMR distinguishes, and itself, this analytical technology can not be distinguished between 7 carbon atoms and 70 carbon atoms.
US patent 4,500,648 (it is for reference to be introduced into this paper) has instructed long chain branching frequency (LCBF) to be represented by equation LCBF=b/Mw, and wherein b is that the weight average long chain branches number and the Mw of per molecule are weight-average molecular weight.Molar mass average value and long chain branching characteristic are measured by gel permeation chromatography and limiting viscosity method.
Other known technology also is used for measuring long chain branches and exists at ethene polymers (comprising ethene/1-octene copolymer).Two kinds of these class methods are and the gel permeation chromatography (GPC-LALLS) of little angle laser light scattering detector lotus root connection and the gel permeation chromatography (GPC-DV) that joins with differential viscosity detector lotus root.Use and the correlation theory of these technology on long chain branches detects had report in the literature.Referring to, for example, Zimm, G.H. and Stockmayer, W.H., J.Chem.Phys., 17,1301 (1949) and Rudin, A., the modernism of polymer characterization, John Wiley ﹠amp; Sons, New York (1991) 103-112 page or leaf.
A.Willem deGroot and P.Steve Chum (being Dow chemical company) have reported some data in the joint meeting of the analytical chemistry in 4 days Augusts in 1994 of St. Louis, Missouri and spectroscopy association (FACSS), show that GPC-DV is used for the useful technology of the existence of quantitative long chain branches in the ethylene copolymer of substantial linear.Especially, deGroot and Chum find, use measured amount and the use of long chain branches in the ethylene homo matter sample of substantial linear of Zimm-Stockmayer equation 13The amount of the long chain branches that C NMR is measured is very identical.
In addition, deGroot and Chum find that the existence of octene does not change the hydrokinetics volume of polyethylene specimen in solution, therefore by knowing that the molecular fraction of octene in sample calculate the molecular weight that causes because of octene short chain branch and improve.By 1-octene short chain branch is removed flatung (deconvolution) to the contribution that molecular weight improves, deGroot and Chum claim that GPC-DC can be used to the content of quantitative long chain branches in the ethylene/octene of substantial linear.
DeGroot and Chum also claim, by the Log (I of GPC-DV mensuration 2Melt index) as the curve shows of the function of Log (GPC weight-average molecular weight) long chain branching of the polyvinyl long chain branching aspect of substantial linear (not being the long chain branching degree) and high pressure, highly branched new LDPE (film grade) (LDPE) have comparability, and obviously be different from the ethene polymers that uses Ziegler-type catalyst such as titanium complex and conventional homogeneous catalyst such as hafnium and vanadium complex to produce.
Opposite with term " ethene polymers of substantial linear ", term " linearity " is meant that polymkeric substance lacks measurable long chain branches that maybe can characterize, promptly, polymkeric substance on average is lower than 0.01 long branch/1000 carbon atom and is replaced, wherein long chain branching is defined as the chain length of at least 6 carbon atoms, is higher than this mean number and then can not uses nuclear magnetic resonance spectrum to distinguish chain length.
" ethene polymers of substantial linear " prepares by using the constrained geometry catalyzer, and characterizes by narrow polymolecularity (molecular weight distribution) with by narrow comonomer distribution." multipolymer " used herein is meant the polymkeric substance of two or more comonomers, for example multipolymer or terpolymer etc., or in other words, the polymkeric substance that is obtained by the polymerization of ethene and at least a other comonomer.Polyvinyl other fundamental characteristics of these substantial linear comprises low residue thing content (promptly, be used for preparing the catalyzer of polymkeric substance, unreacted comonomer and the lower concentration of low-molecular-weight oligomer in the ethene polymers of substantial linear that in polymerization process, produces), with controlled molecular structure, therefore obtain good processing properties, even molecular weight distribution narrow than common olefin polymer.
Though preferably use the ethene polymers of substantial linear to prepare the branched block ethylene polymers thing, can use any two or more dissimilar above-mentioned polyvinyl mixtures equally.Difference in various types of ethene polymerss can illustrate by using for example following polymkeric substance: (i) common LLDPE is with the substantial linear ethene polymers, or (ii) the Alathon of substantial linear with the ethylene/alpha-olefin copolymer of substantial linear, (iii) two or more substantial linear ethene polymerss made from different constrained geometry catalyzer, the (iv) ethene polymers of two or more substantial linear of in different reactor or reaction zone, making, or (v) has different performance such as density, Mw/Mn, I 2Or I 10/ I 2The ethene polymers of two or more substantial linear.Difference in the middle of the ethene polymers in this type of mixture shows that they itself present for example multi-mode density, the Mw/Mn of broadening, and/or the form of multiple melting hump.The polyvinyl mixture of this class, if you are using, can be ideally by using double reaction polymerization process preparation as described below.
Polyvinyl general property
Ethene polymers can be an Alathon, maybe can be ethene and one or more C 3-C 20Alpha-olefin comonomer and/or one or more C 4-C 12The multipolymer of diolefine.Ethene polymers also can be ethene and at least a above-mentioned C 3-C 20The multipolymer of alpha-olefin comonomer and/or diolefine and other unsaturated monomer.Usually, ethene polymers is an ethene and a kind of C only 3-C 20The multipolymer of alpha-olefin and be more preferably ethene and propylene, iso-butylene, 1-butylene, the 1-hexene, the multipolymer of 4-methyl-1-pentene or 1-octene, the multipolymer of therein ethylene and 1-octene is most preferred.Other preferred monomers of copolymerization comprises vinylbenzene, the vinylbenzene that halogen or alkyl replace, vinyl benzo cyclobutene, 1,4-hexadiene and cyclic hydrocarbon (for example cyclopentenes, tetrahydrobenzene and cyclooctene).
Preferred ethene polymers comprises ethene and the 5-50 of 50-95wt%, at least a comonomer of preferred 10-25wt%.The content of comonomer is according to ASTM D-2238, and method B uses infra-red chromatography to measure.
Measure polyvinyl density and generally be according to ASTM D-792 at least about 0.85g/cm 3, normally at least about 0.865g/cm 3, be at least about 0.89g/cm accidentally 3Polyvinyl density generally is 0.96g/cm 3Or lower, 0.93g/cm normally 3Or lower, chance or 0.90g/cm 3Or it is lower.Density measurement normally is made up of clean polymkeric substance, does not promptly have mineral filler and does not contain the polymkeric substance from the aluminium of catalyst residue above 20ppm.
In some cases, described ethene polymers is crystallization and/or semi-crystalline polymer.They generally at room temperature are solid, and can be in room temperature or granulation under by the temperature of chilled water modulation.For example, has density 0.865g/cm 3The ethene/1-octene copolymer of substantial linear at room temperature have about 10% degree of crystallinity.
Polyvinyl molecular weight can use easily according to ASTM D-1238, and 190 ℃/2.16kg[of condition previously known is for " rule (E) " and also be known as I 2] the melt index observed value represent.The molecular weight of melt index values and polymkeric substance is inversely proportional.Therefore, molecular weight is high more, and melt index is low more, though relation is not linear.Polyvinyl I 2Melt index generally is about 0.01g/min (gram/minute) or higher, preferably about 0.1g/10min or higher, more preferably from about 0.5g/10min and most preferably from about 1.0g/10min or higher.Polyvinyl I 2Melt index generally is about 1000g/min or lower, preferably about 500g/min or lower, more preferably from about 250g/min or lower and 100g/min or lower most preferably from about.
The use of two reactor system in the preparation ethene polymers
Multiple reaction device polymerization process, as in US patent 3,914,342, US.SN08/010,958 (application on January 29th, 1993) and US.SN08/208,068 (application on March 8th, 1994) those disclosed, wherein the multiple reaction device can be operated by serial or parallel connection, can be used to prepare ethene polymers ideally usually.When the parallel running reactor, polymerisate separately (still being in the solution) is mixed into a kind of mixture.When series operation multiple reaction device, the product of first reactor or reaction zone wherein adds other monomer and catalyzer by second reactor or reaction zone.
On lesser extent, if the catalyzer of any work enters in second reactor or the district from first reactor or district, the product main (if not fully) of then discharging from second reactor or district is each mixture of polymers of independent preparation in each reactor or district, only when the reactor parallel running.Yet described ethene polymers is believed to comprise resulting product, if monomer is aggregated on the same polymer chain in first and second reactors or district.
After mixed, or after product is discharged from placed in-line end reaction device or district, remove with method well known in the prior art and to desolvate, to reclaim all polymkeric substance together as a kind of product from the product materials flow of parallel reactor.
Each reactor or the district of serial or parallel connection operation can be with regard to various characteristic aspect differences, these characteristic ratios are the type of employed catalyzer in each reactor or district in this way, be added into the type of the alpha-olefin comonomer in each reactor or the district, or the temperature of each reactor or district's operation.For example, the constrained geometry catalyzer can use in a reactor or district and Z-type catalyst uses in another.When the reactor parallel running, the unnecessary output material that is equal to share that contains each reactor of the materials flow of merging or ejecta (from them, reclaiming final product).

The presentation of results of embodiment 19-20 and reference examples F-G carry out blended importance with molding under certain condition during with polymkeric substance (as polyolefin resin) blend when branched block ethylene polymers thing and amine-functionalized polymers (as polymeric amide), should make it possible under these conditions from branched ethylene polymer and amine-functionalized polymers formation branched block ethylene polymers thing.This type of condition comprises at first in independent equipment preparation branched block ethylene polymers thing and then with it and molding polymer blending, or in same equipment such as forcing machine, mix all three kinds of materials, but carry out so that the reaction of amine-functionalized polymers and branched ethylene polymer forms the branched block ethylene polymers thing according to a definite sequence, because molding can hinder this reaction with the existence of polymkeric substance.
For example, the composition of reference examples F and polypropylene component blend can prepare the branched block ethylene polymers thing from it.Yet, the preparation of reference examples F not can with polyacrylic blend in produce the branched block ethylene polymers thing because three kinds of components of all of reference examples F are mixed and blended in forcing machine simultaneously then by dried.When same component is used at first prepare the branched block ethylene polymers thing in embodiment 19 (from E/MAH branched ethylene polymer and polymeric amide), resulting have polyacrylic blend will obtain a kind of composition that demonstrates significantly high Ai Zuode, welded bonds and dart-drop value.Even when with reference examples G in when mixing E/MAH branched ethylene polymer, polymeric amide and polyolefine simultaneously under the same high temperature, shear conditions at the Banbury mixing machine, the performance of blended composition can be than reference examples F better, and reach those that are inferior to embodiment 20 (wherein the preparation of branched block ethylene polymers thing is being carried out finishing before the melt blending with polymkeric substance with molding).
Have been found that in general the branched block ethylene polymers thing demonstrates improved rheological property, with each component (preparing the former) from described component Comparatively speaking.For example, the branched block ethylene polymers thing, when testing by the dynamic mechanical spectrometer, under low shearing speed, demonstrate than ethene polymers or the much higher viscosity of branched ethylene polymer, also demonstrate much higher shearing sensibility in addition than its arbitrary precursor because under high speed shear its viscosity degradation to by the about identical level of the shown viscosity that goes out of ethene polymers or branched ethylene polymer.Therefore the tan δ value of branched block ethylene polymers thing also is superior to the value of ethene polymers or branched ethylene polymer, is to shear and the indication of high melt elasticity (high storage modulus) under high-shear low.
And, have now found that the branched block ethylene polymers thing has corresponding influence to containing molding with the blend of polymkeric substance.This type of blended composition ratio under low shearing only goes out higher melt strength and elasticity with the composition exhibiting of ethene polymers or branched ethylene polymer modification, and this blend has enough shearing sensibilities, and it is thinning to identical with branched ethylene polymer basically viscosity under high-shear.For example, Figure 20 show for ethene/tapping point multipolymer and with as amine-functionalized multipolymer from the branched block ethylene polymers thing blend of the polyamide preparation of various consumption levels the viscosity of polypropylene under various velocity of shear.The blend that contains the branched block ethylene polymers thing under low the shearing, have higher viscosity but under high-shear thinning to the identical degree of blend that only contains ethene/tapping point multipolymer.Figure 21 provides tan δ for same group blend, and it is that out-of-phase modulus is divided by storage modulus.Wherein polypropylene and the blend of branched block ethylene polymers thing rather than only have lower tan δ and therefore have higher storage modulus with the copolymer blended composition of ethene/tapping point.Higher storage modulus has been represented a large amount of elasticity recovered.The mensuration of tan δ value is carried out with currently known methods, as from Melt Rheology and Its Role in Plastic Processing (melt rheology and its effect plastic working), Dealy and Wissbrun, Van Nostrand, those methods that nineteen ninety obtains.
These improvement on performance it is believed that the trend that is dispersed in the blended composition with the branched block ethylene polymers thing is relevant, and the dispersive mode should make amine-functionalized polymers be broken up into the submicron particles form in the particle of branched ethylene polymer and have bigger particle size uniformity.On the contrary, when amine-functionalized polymers was blended in random, the physical blending thing with branched ethylene polymer simply rather than at first is formed the branched block ethylene polymers thing as a component, the amine-functionalized polymers that is dispersed in the ethene polymers had the less homogeneity of particle size or does not have homogeneity at all; Amine-functionalized polymers also can be used as big, many micron particles and is dispersed in molding with in the polymeric matrix resin in this case, but to ethene polymers without any association.
Therefore, in preferred embodiments, amine-functionalized polymers in the branched block ethylene polymers thing is scattered in the branched ethylene polymer with particle form, wherein about 50% or more, usually about 65% or more, about frequently 80% or more and accidental about 90% or granularity that more particles had be in about 120% scope of about 80%-of the mean sizes of whole amine-functionalized polymers particle cluster in being scattered in the particle of branched ethylene polymer.
When the particle cluster of the very uniform small grain size of the conduct of the amine-functionalized polymers in the branched block ethylene polymers thing is scattered in the branched ethylene polymer, the particle of branched ethylene polymer itself is less and more is evenly distributed in molding with in the polymeric matrix, makes composition have excellent elastic impact intensity.On the contrary, when the amine-functionalized polymers particle only is component that is not having in random, the physical blending thing of branched block ethylene polymers thing terpolymer, then the branched ethylene polymer particle is bigger and/or the branched ethylene polymer particle swarm trends towards assembling and producing a kind of territory, in the territory as be both big particle and can bring into play effective function.So, in another embodiment, branched ethylene polymer particulate granularity and the ratio that is dispersed in amine-functionalized polymers particulate mean particle size wherein, when when they have prepared the branched block ethylene polymers thing, being significantly less than branched ethylene polymer particulate granularity and being dispersed in the ratio of amine-functionalized polymers particulate mean particle size wherein, only is in random, the physical blending thing during component when not forming branched block ethylene polymers thing and amine-functionalized polymers.
Correspondingly, if use excessive amine-functionalized polymers, then can lose the beneficial effect that forms the branched block ethylene polymers thing in the blend composition.Will be offset by the unhindered amina functionalized polymeric by the value that amine-functionalized polymers increased that forms the final block on the branched block ethylene polymers thing, the latter understands crosslinked or forms crystal domain, and this territory is brittle and makes blend composition improve notch sensitivity.

Data show among the Table I X, and when using polymer blending with molding, the branched block ethylene polymers thing can be produced the composition of the required balance with various performances effectively.It contains some components reference examples A1-, can prepare the branched block ethylene polymers thing the PC blend from these components but does not prepare-have the welded bonds value lower than embodiment 25.Other reference examples that contains the olefin polymer of some other forms separately has the performance of good individual types, but they do not resemble and on all performances of three types the ideal balance are arranged the embodiment 25.For example, reference examples C1-E1 all has very high anisotropy, but has extremely low weld line strength.Data can be reached a conclusion from Table VIII, in blend composition, utilize the very effective measure of olefin polymer to be to use it to prepare branched block ethylene polymers thing (as described herein), use conduct of branched block ethylene polymers thing and the blending and modifying agent of molding then with polymkeric substance.
Improvement on these performances it is believed that the trend that is dispersed in the blend composition with the branched block ethylene polymers thing is relevant, and its dispersing mode should make polyester as there being the submicron particles of high particle size uniformity to be dispersed in the particle of ethene/branch point multipolymer.On the contrary, when polyester is blended in random, the physical blending thing with ethene/branch point multipolymer simply rather than at first forms the branched block ethylene polymers thing as a component, be dispersed in polyester in the ethene polymers and will have very little particle size uniformity or do not have at all; In this case polyester as big, a plurality of micron-sized particles dispersed molding with the polymeric matrix resin in but can any association not arranged with ethene polymers.
Therefore, in preferred embodiments, polyester in the branched block ethylene polymers thing is used as particles dispersed in ethene/tapping point multipolymer, wherein about 50% or higher, usually about 65% or higher, about infrequently 80% or more and accidental about 90% or granularity that more particles had be in about 120% scope of about 80%-of the mean sizes of whole polyester granulate cluster in the particle that is scattered in ethene/tapping point multipolymer.
When the particle cluster of the very uniform small grain size of the conduct of the polyester in the branched block ethylene polymers thing is scattered in ethene/tapping point multipolymer, the particle of ethene/tapping point multipolymer itself is less and more is evenly distributed in molding with in the polymeric matrix, makes composition have excellent elastic impact intensity.On the contrary, when polyester granulate only is component in do not having that terpolymer forms random, the physical blending thing, then ethene/tapping point copolymer pellet is bigger and/or ethene/tapping point copolymer pellet group trends towards assembling and producing a kind of territory, and this territory is as being that very large particle is brought into play more effective effect.So, in another embodiment, the granularity of ethene/tapping point copolymer pellet and the ratio that is dispersed in the mean particle size of polyester granulate wherein, when when they have prepared the branched block ethylene polymers thing, granularity that is significantly less than ethene/tapping point copolymer pellet and the ratio that is dispersed in the mean particle size of polyester granulate wherein, the latter is only to be in random, the physical blending thing during component when not forming segmented copolymer and polyester.
According to embodiment 25 in similarly mode prepare the composition of embodiment 26-29.The branched block ethylene polymers thing that uses in the composition of embodiment 26-29 is to react in the presence of p-methylphenyl sulfimide potassium (" KPTSM ") catalyzer by the polyethylene terephthalate with limiting viscosity 0.59 and " substantial linear " ethene polymers of containing the maleic anhydride tapping point to prepare.Though the branched block ethylene polymers thing by means of Preparation of Catalyst is preferred,, also be useful product as the polymkeric substance that in embodiment 26, uses without the polymkeric substance of Preparation of Catalyst.The branched block ethylene polymers thing that uses in each embodiment contains maleic anhydride tapping point " substantial linear " ethene polymers and 70wt% polyethylene terephthalate preparation from 30wt%.Each blend composition is from the preparation of the branched block ethylene polymers thing of 93wt% polycarbonate and 7wt%.The KPTSM catalyst consumption of using in embodiment 27-29, parts per million part (ppm) expression with respect to the combined wt of E/MAH multipolymer and polyethylene terephthalate (from they preparation branched block ethylene polymers things) is shown in the following table.
For " welded bonds " sample that in the twoport mould, forms, under 25 ℃, measure the shock resistance of embodiment 26-29 according to ASTM regulation D 256-84 (method A) by Ai Zuode test (" Izod ") with jam welding.Sample is unnotched, and is placed in and makes the upper surface high 1mm of weld than bench vice anchor clamps on the bench vice.The Ai Zuode test result of embodiment 26-29 all is to make record for 11 times of the composition of each sample tests, and each time result is classified as " not fracture ", " part fracture " or " brittle rupture " in 11 tests.The brittle rupture of the sample in following table is meant the fracture that impels sample separation to become two individual sheets, and sample separates and major portion maintenance linking significantly in the part fracture.The Ai Zuode test value that each embodiment write down is the mean value of those test values of 11 tests of the part or the various samples of brittle rupture.Ai Zuode result represents that with ft-lb/in this is the standard deviation of the Ai Zuode value of each group part or brittle rupture.

The presentation of results of embodiment 26-29 in preparation process as the branched block ethylene polymers thing of blending and modifying agent in the composition of embodiment 27-29, KPTSM produces a kind of branched block ethylene polymers thing as the existence of catalyzer is feasible, and this polymkeric substance is than there not being the prepared branched block ethylene polymers thing of catalyzer to improve the shock strength of composition better.Although the composition exhibiting of embodiment 26 goes out considerable Ai Zuode value, in the preparation process of the branched block ethylene polymers thing that is used for blend, use the composition of the embodiment 27-29 of relatively large KPTSM catalyzer also to show improved Ai Zuode value and very little brittle rupture.
