Description
Foreliggende oppfinnelse vedrører nye metallocenforbindelser og nærmere bestemt visse overgangsmetallforbindelser fra gruppe IVB i det periodiske system. Disse forbindelsene kan anvendes i et katalysatorsystem sammen med en alumoksanforbindelse for fremstilling av polyolefiner, spesielt polyetylen, polypropylen og a-olefin-kopolymerer av etylen og propylen som har en høy molekylvekt. Katalysatorsystemet er meget aktivt ved lave forhold for aluminium til gruppe IVB-overgangsmetallet, og katalyserer således fremstillingen av et polyolefinprodukt som inneholder lave nivåer av kataly-satorrest.
Som velkjent eksisterer det forskjellige prosesser og katalysatorer for homopolymerisasjon eller kopolymerisasjon av olefiner. For mange anvendelser er det av største viktighet for et polyolefin å ha en høy vektmidlere molekylvekt samtidig som det har en relativt snever molekylvektfordeling. En høy vektmidlere molekylvekt gir når den er ledsaget av en snever molekylvektfordeling, et polyolefin eller en etylen-a-olefin-kopolymer med høye styrkeegenskaper.
Tradisjonelle Ziegler-Natta-katalysatorsystemer - en overgangsmetallforbindelse som er kokatalysert med en aluminiumalkylforbindelse - er i stand til å produsere polyolef iner som har en høy molekylvekt, men en bred molekylvektfordeling.
I den senere tid har det blitt utviklet et katalysatorsystem hvori overgangsmetallforbindelsen har to eller flere cyklopentadienylring-ligander, hvor en slik metallforbindelse er betegnet en metallocen, som katalyserer fremstillingen av olefinmonomerer til polyolefiner. Følgelig har metallocenforbindelser av gruppe IVB-metaller, spesielt titanocen og zirkonocen, blitt benyttet som overgangsmetallkomponenten i et slikt "metallocen"-holdig katalysatorsystem for fremstilling av polyolefiner og etylen-a-olefin-kopolymerer. Når slike metallocener kokatalysseres med en aluminiumalkyl-slik tilfellet er med et Ziegler-Natta-katalysatorsystem av tradisjonell type - er den katalytiske aktiviteten til et slikt metallocen-katalysatorsystem vanligvis for lav til å være av noen kommersiell interesse.
Det har siden blitt kjent at slike metallocener kan kokataly-seres med en alumoksanforbindelse, istedenfor en aluminiumalkylforbindelse, for å tilveiebringe et metallocen-katalysatorsystem av høy aktivitet som katalyserer fremstillingen av polyolefiner.
En rekke forskjellige gruppe IVB-overgangsmetallforbindelser av metallocentypen har blitt angitt som mulige kandidater for et alumoksan-kokatalysert katalysatorsystem. Selv om bis(cyklopentadienyl)-gruppe IVB-overgangsmetallforbindelser har vært den mest foretrukne og omfattende undersøkte type av metallocener for bruk i metallocen/alumoksan-katalysator for polyolefinfremstilling, så har det fremkommet forslag om at mono- og tris(cyklopentadienyl)-overgangsmetallforbindelser også kan være nyttige. Se, f.eks. US-patenter 4 522 982, 4 530 914 og 4 701 431. Slike mono(cyklopentadienyl)-overgangsmetallforbindelser som hittil har vært foreslått som kandidater for en metallocen/alumoksan-katalysator er mono(cyklopentadienyl)-overgangsmetalltrihalogenider og
-trialkyler.
Mer nylig har publikasjonen WO 87/03887 beskrevet bruken av en sammensetning som omfatter et overgangsmetall som er koordinert til i det minste en cyklopentadienyl- og minst en heteroatomligand som en komponent av metallocentypen for bruk i et metallocen/alumoksan-katalysatorsystem for a-olefin-polymerisasjon. Sammensetningen er bredt definert som et overgangsmetall, fortrinnsvis i gruppe IVB i det periodiske system som er koordinert med minst en cyklopentadienylligand og en til tre hetereoligander, idet resten av koordinasjons-behovet er tilfredsstilt med cyklopentadienyl- eller hydrokarbylligander. Det beskrevne metallocen/alumoksan-katalysatorsystemet er Illustrert utelukkende under hen-visning til overgangsmetallforbindelser som er bis(cyklopentadienyl)-gruppe IVB-overgangsmetallforbindelser.
Videre, ved den tredje kjemiske kongress i Nord-Amerika holdt i Toronto, Canada, juni 1988, rapporterte John Bercaw forsøk på å benytte en forbindelse av et gruppe IIIB-overgangsmetall koordinert til en enkel cyklopentadienyl-heteroatombrodannet ligand som et katalysatorsystem for polymerisasjon av olefiner. Selv om en viss katalytisk aktivitet ble observert under de benyttede betingelser, så var aktivltetsgraden og de egenskaper som ble observert i det resulterende polymer-produkt nedslående for en oppfatning at en slik overgangs-metallforblndelse på nyttig måte kunne anvendes for kommer-sielle polymerisasjonsprosesser.
Det eksisterer fremdeles et behov for katalysatorsystemer som tillater fremstilling av polyolefiner av høyere molekylvekt og ønskelig med en snevrere molekylvektfordeling.
I tråd med dette er det ifølge foreliggende oppfinnelse tilveiebragt en metallocenforbindelse, som er kjennetegnet ved at den har den generelle formel:
hvor:
M og M' er Zr, Hf eller Tl;
(C5H4_XRX) er en cyklopentadienylring som er substituert med fra 0 til 4 grupper R, <M>x<H> er 0, 1, 2, 3 eller 4 som betegner substitusjonsgraden, og hver substituentgruppe R er uavhengig et radikal valgt fra C]—C2o-nydroliarDylradikaler, substituerte Ci-^o-hydro^rbylradikaler hvor ett eller flere hydrogenatomer er erstattet med et halogenatom, C^—C20-hydrokarbylsubstituerte metalloidradikaler hvor metalloidet er valgt fra gruppe IVA i det periodiske system, og halogen-radikaler, eller (C5H4_XRX) er en cyklopentadienylring hvori to tilstøtende R-grupper er sammenføyet fra en C4-C2o_ring-struktur slik at det oppnås en mettet eller umettet polycyklisk cyklopentadienylligand;
(JR<*>Z_2) er en heteroatomligand hvor J er et element med koordinasjonstall 3 fra gruppe VA eller et element med koordinasjonstall 2 fra gruppe VIA i det periodiske system, og hver R' er uavhengig et radikal valgt fra C]— C2o~hydrokarbylradikaler, substituerte Cj—C2o~nydrokarbylradikaler hvor ett eller flere hydrogenatomer er erstattet med et halogenatom, og "z" er koordinasjonstallet til elementet J;
hver Q er uavhengig en hvilken som helst enverdig, anionisk ligand eller to 0'er er et toverdig, anionisk chelaterings-middel;
B er en kovalent brodannende gruppe inneholdende et element fra gruppe IVA eller VA i det periodiske system, valgt fra dialkyl-, alkyl-, aryl- eller diarylsilisium- eller-germaniumradikal, eller fenylamido, t-butylamido, metylamido, t-butylfosfido, etylfosfido, fenylfosfido, metylen, dimetylmetylen, dietylmetylen, etylen, dimetyletylen, dietyletylen, dipropyletylen; og
L er en Lewis-base hvor "w" betegner et tall fra 0 til 3, men unntatt forbindelser av den generelle formel:
hvor M har den ovenfor angitte betydning, (C5H4_X»R<2>X») er en cyklopentadienylring som er substituert med fra 0 til 4 R<2->grupper, x' er 1, 2, 3 eller 4, og hvor R<2> og de i gruppene Si(R<2>)2 og YR<2> er uavhengig valgt fra hydrogen, silyl, alkyl, aryl og kombinasjoner derav med opptil 10 karbonatomer,
Q' er uavhengig valgt fra halogen, alkyl, aryl, fenoksy, alkoksy med opptil 10 karbonatomer eller -NR<2> hvor R<2> har den ovenfor angitte betydning, idet n er 1 eller 2 avhengig av valensen til M, og Y er nitrogen eller fosfor.
Det er foretrukket heteroatomet i ligander JR *z_2 er nitrogen, fosfor, oksygen eller svovel. Videre er det foretrukket at M og/eller M' er zirkonium eller hafnium.
Det foretrekkes at gruppen Q er et hydrid-, halogen- eller hydrokarbylradlkal som er forskjellig fra en cykllsk cyklopentadienylgruppe. Videre er det ytterligere foretrukket at gruppen Q er substituert eller usubstituert Cj-C2o-hyclro-karbyl, alkoksyd, aryloksyd, amid, arylamid, fosfid eller arylfosfid, forutsatt at når en hvilken som helst av Q er en hydrokarbylgruppe, så er en slik Q-gruppe forskjellig fra (C5H4_XRX), eller begge er sammen en alkylidengruppe eller en hydrokarbylmetallocykelgruppe.
Eksempler på nevnte polycykliske cyklopentadienylligand er lndenyl, tetrahydroindenyl, fluorenyl eller oktahydro-fluorenyl.

Egnede hydrokarbyl- og substituert hydrokarbylradikaler som, som en R-gruppe, kan være benyttet istedenfor minst ett hydrogenatom i cyklopentadienylringen, vil inneholde fra 1 til 20 karbonatomer og innbefatte rette og forgrenede alkylradikaler, cykliske hydrokarbonradikaler, alkylsubstituerte. cykliske hydrokarbonradikaler, aromatiske radikaler, alkylsubstituerte aromatiske radikaler og cyklopentadienyl-dienyl-p-n-butylfenylamidozirkoniumdiklorid, dimetylsilyl-te trame tyl cyklopent adieny 1 -p-n-butylf enyl aml dohafnium-diklorid. For illustrerende formål vil de ovenfor angitte forbindelser og de som er permutert fra tabell 1 ikke innbefatte Lewis-baseliganden (L). Betingelsene under hvilke komplekser inneholdende Lewls-baseligander slik som eter eller de som danner dimerer oppnås, bestemmes av den sterlske massen til ligandene omkring metallsenteret. For eksempel har t-butylgruppen i Me2Si(Me4C5)(N-t-Bu)ZrCl2 større steriske behov enn fenylgruppen i Me2Si(Me4C5)(NPh)ZrCl2<*>Et20 hvorved eterkoordinasjon i førstnevnte forbindelse ikke tillates. Likeledes, på grunn av den nedsatte steriske massen til trimetylsilylcyklopentadienylgruppen i [Me2Si(Me3SiC5H3)-(N-t-Bu)ZrCl2]2 1 forhold til den til tetrametylcyklopenta-dienylgruppen i Me2Si(Me4C5)(N-t-Bu)ZrCl2, så er førstnevnte forbindelse dimerisk og sistnevnte ikke.

Forbindelsene kan fremstilles ved omsetning av en cyklopenta-dienyllitiumforbindelse med en dihalogenforbindelse hvorved et lltiumhalogenidsalt frigjøres og en monohalogensubstituent blir kovalent bundet til cyklopentadienylforbindelseh. Det således substituerte cyklopentadlenylreaksjonsproduktet blir deretter omsatt med et litiumsalt av et fosfid, oksyd, sulfid eller amid (for illustrasjonsformål et litiumamid) hvorved halogenelementet i monohalogensubstituentgruppen i reaksjons-produktet reagerer slik at det frigjøres et lltiumhalogenidsalt og amindelen i litlumamidsaltet blir kovalent bundet til substituenten i cyklopentadienylreaksjonsproduktet. Det resulterende aminderivatet av cyklopentadienylproduktet blir deretter omsatt med en alkyllitiumreagens hvorved de labile hydrogenatomene, ved karbonatomet i cyklopentadienylforbin-delsén og ved nitrogenatoinet i amindelen som er kovalent bundet til substituentgruppen, reagerer med alkylgruppen i 11tiumalkylreagensen til frigjøring av alkanen og dannelse av et litiumsalt av cyklopentadienylforbindelsen. Deretter fremstilles foreliggende metallocenforbindelser ved omsetning av dilitiumsalt-cyklopentadienylforbindelsen med et av gruppe IVB-overgangsmetallene, Zr, Hf eller Ti, fortrinnsvis et halogenid derav.
Fordelaktige forbindelser er de hvor B—gruppebroen er en dialkyl-, diaryl- eller alkylarylsilan, eller metylen eller etylen. Eksempler på de mer foretrukne typer av brodannede grupper er dimetylsilyl-, metylfenylsilyl-, dietylsilyl-, etylfenylsilyl-, difenylsilyl-, etylen- eller metylen-brodannede forbindelser. Mest foretrukket av de brodannede forbindelsene er dimetylsilyl-, dietylsilyl- og metylfenylsilyl -brodannede forbindelser.
For å illustrere typer av metallocenforbindelser kan en hvilken som helst kombinasjon av gruppene i tabell 1 velges. Et eksempel på en forbindelse ville være dimetylsilyl-cyklopentadienyl-t-butylamidodiklorzirkonium.
Foreliggende metallocener kan som nevnt anvendes sammen med alumoksanforbindelser i katalysatorsystemer. Alumoksankomponenten 1 slike katalysatorsystemer er en ollgomer-forbindelse som kan representeres ved den generelle formel (R<2->Al-0)m som er en cyklisk forbindelse, eller kan være R<3>(R<4->Al-0-)m-AlR<5>2 som er en lineær forbindelse. En alumoksan er generelt en blanding av både den lineære og den cykliske forbindelsen. I den generelle alumoksanformelen er R2, R<3>, r<4> og R<5> uavhengig en enverdig anionisk ligand slik som et Cj—Cs-alkylradikal, f.eks. metyl, etyl, propyl, butyl, pentyl eller halogenid og "m" er et helt tall fra 1 til 50. Mest foretrukket er R<2>, R<3>, R<4> og R5 hver metyl og "m" er minst 4. Når et alkylaluminiumhalogenid anvendes i fremstillingen av alumoksan, så kan en eller flere av R<2->R^ være halogenid.
Anvendelse av foreliggende metallocenforbindelse i katalysatorsystemer for fremstilling av polyolefiner skal omtales i det nedenstående. Således kan et katalysatorsystem omfattende foreliggende metallocenforbindelse hensiktsmessig fremstilles ved å anbringe en utvalgt metallocenforbindelse og en utvalgt alumoksanforbindelse, i en hvilken som helst rekkefølge, i et alkan- eller aromatisk hydrokarbonoppløsningsmiddel, fortrinnsvis et som også er egnet for bruk som et polymerisa-sjonsfortynningsmiddel. Når hydrokarbonoppløsningsmldlet som benyttes også er egnet for bruk som et polymerisasjons-fortynningsmiddel, så kan katalysatorsystemet fremstilles in situ i polymerisasjonsreaktoren. Alternativt kan katalysatorsystemet fremstilles separat, i konsentrert form, og tilsettes til polymerisasjonsfortynningsmidlet i en reaktor. På den annen side kan, om ønsket, komponentene i katalysatorsystemet fremstilles som separate oppløsningsmidler og tilsettes til polymerlsasjonsfortynningsmidlet i en reaktor, i passende forhold, slik det er egnet for en kontinuerlig væskepolymerisasjonsreaksjonsmetode. Alkan og aromatiske hydrokarboner egnet som oppløsningsmidler for dannelse av katalysatorsystemet og også som et polymerisasjons-fortynningsmiddel er eksemplifisert ved rette og forgrenede hydrokarboner slik som isobutan, butan, pentan, heksan, heptan, oktan og lignende, cykliske og alicykliske hydrokarboner slik som cykloheksan, cykloheptan, metylcykloheksan, metylcykloheptan og lignende, og aromatiske og alkylsubstituerte aromatiske forbindelser slik som benzen, toluen, xylen og lignende. Egnede oppløsningsmidler innbefatter også flytende olefiner som kan virke som monomerer eller komono-merer inkludert etylen, propylen, 1-buten, 1-heksen og lignende.
Det oppnås vanligvis optimale resultater når metallocen-forbindelsen er til stede i polymeriasjonsfortynningsmidlet i en konsentrasjon fra 0,0001 til 1,0 mmol/liter fortynnings-middel og alumoksankomponenten er til stede i en mengde for tilveiebringelse av et molarforhold for aluminium til overgangsmetall på fra 1:1 til 20 000:1. Tilstrekkelig oppløsningsmiddel bør benyttes for derved å tilveiebringe tilstrekkelig varmeoverføring bort fra katalysatorkomponentene under reaksjonen og for å oppnå god blanding.
Katalysatorsystembestanddelene, dvs. metallocenforbindelsene, alumoksanforbindelsen og polymerisasjonsfortynningsmidlet kan tilsettes til reaksjonsbeholderen på hurtig eller langsom måte. Temperaturen som holdes under kontrakten mellom katalysatorkomponentene kan variere sterkt, slik som f.eks. fra -10 til 300°C. Høyere eller lavere temperaturer kan også benyttes. Under dannelsen av katalysatorsystemet blir reaksjonsblandingen fortrinnsvis holdt innenfor en temperatur fra 25 til 100°C, mest foretrukket ca. 25°C.
Til enhver tid blir de individuelle katalysatorsystemkompo-nenter samt katalysatorsystemet når dette først er dannet, beskyttet overfor oksygen og fuktighet. Reaksjonene blir derfor utført i en oksygen- og fuktighetsfri atmosfære og, når katalysatorsystemet utvinnes separat, blir det utvunnet i en oksygen- og fuktighetsfri atmosfære. Reaksjonene blir derfor fortrinnsvis utført i nærvær av en inert tørr gass slik som f.eks. helium og nitrogen.
Når det gjelder anvendelse av foreliggende metallocenforbindelser i et katalysatorsystem for polymerisasjons-formål, vises det til NO-patentsøknad 920971 og den der angitte omtale og eksemplifisering.
Følgende eksempler illustrerer fremstilling av spesielle metallocenforbindelser ifølge oppfinnelsen.
Alle fremgangsmåter ble foretatt under en inert atmosfære av helium eller nitrogen. Valg av oppløsningsmiddel er ofte valgfrie, og f.eks. i de fleste tilfeller kan enten pentan eller 30-60 petroleumeter benyttes om hverandre. De litium-holdige amidene ble fremstilt fra tilsvarende aminer og enten n-BuLi eller MeLi. Publiserte metoder for fremstilling av LiHC5Me4 innbefatter CM. Fendrick et al., Organometallics, 3. 819, (1984) og F.H. Kohler og K.H. Doll, Z. Naturforsch., 376, 144 (1982). Andre litierte substituerte cyklopenta-dienylforbindelser fremstilles typisk fra den tilsvarende cyklopentadienylligand og n-BuLi eller MeLi, eller ved omsetning av MeLi med den passende fulvenforbindelsen. ZrCl4 og HfCl4 ble innkjøpt fra enten Aldrich Chemical Company eller Cerac. Aminer, silaner og litiumreagenser ble innkjøpt fra Aldrich Chemical Company eller Petrarch Systems. Metylalumoksan ble levert av enten Sherring eller Ethyl Corp.
