Abstract

The application relates to a catalyst system containing a metallocene, a co-catalyst, a support material and optionally, other organometal compounds. The inventive catalyst system can be used advantageously for polymerising olefins without using aluminoxanes such as methylaluminoxane (MAO), which is usually used in considerable excess as a co-catalyst. A high level of catalyst activity and good polymer morphology are guaranteed nonetheless. The catalyst activity can be increased significantly by adding hydrogen during the polymerisation of the olefins.

Das Katalysatorsystem kann vorteilhaft zur Polymerisation von Olefinen eingesetzt werden, wobei auf die Verwendung von Aluminoxanen wie Methylaluminoxan (MAO), das üblicherweise in hohem Überschuß eingesetzt werden muß, als Cokatalysator verzichtet werden kann und dennoch eine hohe Katalysatoraktivität und gute Polymermorphologie erzielt wird.Co-catalyst, support material and optionally other organometallic compounds. The catalyst system can advantageously be used for the polymerization of olefins, it being possible to dispense with the use of aluminoxanes, such as methylaluminoxane (MAO), which usually has to be used in large excess, as cocatalyst, and yet high catalyst activity and good polymer morphology are achieved.
Die Rolle von kationischen Komplexen bei der Ziegler-Natta-Polymerisation mit Metallocenen ist allgemein anerkannt (H.H. Brintzinger, D. Fischer, R. Mülhaupt, R. Rieger, R. Waymouth, Angew. Chem. 1995, 107, 1255-1283).The role of cationic complexes in Ziegler-Natta polymerization with metallocenes is generally recognized (H.H. Brintzinger, D. Fischer, R. Mülhaupt, R. Rieger, R. Waymouth, Angew. Chem. 1995, 107, 1255-1283).
Die Darstellung kationischer Alkylkomplexe eröffnet die Möglichkeit MAO-freie Katalysatoren mit vergleichbarer Aktivität, wobei der Co-Katalysator nahezu stöchiometrisch eingesetzt werden kann, zu erhalten.The representation of cationic alkyl complexes opens up the possibility of obtaining MAO-free catalysts with comparable activity, the co-catalyst being able to be used almost stoichiometrically.

EP-A-0,558,158 beschreibt zwitterionische Katalysatorsysteme, die aus Metallocendialkyl-Verbindungen und Salzen der Form [R3NH]+ [B(C6H5)4]- dargestellt werden. Die Umsetzung eines solchen Salzes mit z.B. Cp2ZrMe2 liefert durch Protolyse unter Methanabspaltung intermediär ein Zirkonocenmethyl-Kation. Dieses reagiert über C-H-Aktivierung zum Zwitterion Cp2Zr+-(m-C6H )-BPh3- ab.EP-A-0,558,158 describes zwitterionic catalyst systems which are prepared from metallocene dialkyl compounds and salts of the form [R 3 NH] + [B (C 6 H 5 ) 4 ] -. The reaction of such a salt with, for example, Cp2ZrMe 2 provides an intermediate zirconocenemethyl cation by protolysis with elimination of methane. This reacts via CH activation to the zwitterion Cp2Zr + - (m-C6H) -BPh 3 -.
Das Zr-Atom ist dabei kovalent an ein Kohlenstoffatom des Phenylrings gebunden und wird über agostische Wasserstoffbindungen stabilisiert.US-A-5, 348,299 beschreibt zwitterionische Katalysatorsysteme, die aus Metallocendialkyl- Verbindungen und Salzen der Form [RsNH]+ [B(C6F5) ]- durch Protolyse dargestellt werden. Die C-H-Aktivierung als Folgereaktion unterbleibt dabei. EP-A-0,426,637 nutzt ein Verfahren in dem das Lewis-saure CPh3 + Kation zur Abstraktion der Methylgruppe vom Metallzentrum eingesetzt wird. Als schwach koordinierendes Anion fungiert ebenfalls B(C6F5)4-.The Zr atom is covalently bound to a carbon atom of the phenyl ring and is stabilized via agostic hydrogen bonds. US-A-5, 348,299 describes zwitterionic catalyst systems which consist of metallocendialkyl compounds and salts of the form [RsNH] + [B (C 6 F 5 )] - can be represented by protolysis. The CH activation as a subsequent reaction does not occur. EP-A-0,426,637 uses a method in which the Lewis acidic CPh 3 + cation is used for the abstraction of the methyl group from the metal center. B (C 6 F 5 ) 4 - also acts as a weakly coordinating anion.
Eine industrielle Nutzung von Metallocen-Katalysatoren fordert eine Heterogenisierung des Katalysatorsystems, um eine entsprechende Morphologie des resultierenden Polymers zu gewährleisten. Die Trägerung von kationischen Metallocen-Katalysatoren auf Basis der oben genannten Borat-Anionen ist in WO- 91/09882 beschrieben. Dabei wird das Katalysatorsystem, durch Aufbringen einerIndustrial use of metallocene catalysts requires heterogenization of the catalyst system in order to ensure an appropriate morphology of the resulting polymer. The support of cationic metallocene catalysts based on the above-mentioned borate anions is described in WO 91/09882. The catalyst system, by applying a
Dialkylmetallocen-Verbindung und einer Brönsted-sauren, quatären Ammonium- Verbindung, mit einem nichtkoordinierenden Anion wie Tetrakis-pentafluor- phenylborat, auf einem anorganischen Träger, gebildet. Das Trägermaterial wird zuvor mit einer Trialkylaluminium-Verbindung modifiziert. Nachteil dieses Trägerungsverfahren ist, daß nur ein geringer Teil des eingesetztenDialkylmetallocen compound and a Bronsted acidic, quaternary ammonium compound, with a non-coordinating anion such as tetrakis-pentafluorophenylborate, formed on an inorganic carrier. The carrier material is previously modified with a trialkyl aluminum compound. The disadvantage of this carrier method is that only a small part of the one used
Metallocens Physisorbtion an dem Trägermaterial fixiert ist. Bei der Dosierung des Katalysatorsystems in den Reaktor kann das Metallocen leicht von der Trägeroberfläche abgelöst werden. Dies führt zu einer teilweisen homogen verlaufenden Polymerisation, was eine unbefriedigende Morphologie des Polymers zur Folge hat.Metallocens physisorbtion is fixed on the carrier material. When the catalyst system is metered into the reactor, the metallocene can easily be detached from the support surface. This leads to a partially homogeneous polymerization, which results in an unsatisfactory morphology of the polymer.
In WO-96/04319 wird ein Katalysatorsystem beschrieben, in welchem der Cokatalysator kovalent an das Trägermaterial gebunden ist. Dieses Katalysatorsystem weist jedoch eine geringe Polymerisationsaktivität auf, zudem kann die hohe Empfindlichkeit der geträgerten kationischen Metallocen-WO-96/04319 describes a catalyst system in which the cocatalyst is covalently bound to the support material. However, this catalyst system has a low polymerization activity, and the high sensitivity of the supported cationic metallocene can
Katalysatoren zu Problemen bei der Einschleusung in das Polymerisationssystem führen.Catalysts lead to problems with the introduction into the polymerization system.
Es war daher wünschenswert ein Katalysatorsystem zu entwickeln, das wahlweise vor dem Einschleusen in den Reaktor bereits aktiviert ist oder erst im Polymerisationsautoklav aktiviert wird.It was therefore desirable to develop a catalyst system that is either activated before it is introduced into the reactor or that is only activated in the polymerization autoclave.
Die Aufgabe bestand darin ein Katalysatorsystem zur Verfügung zu stellen, welches die Nachteile des Standes der Technik vermeidet und trotzdem hohe Polymersationsaktivitäten und eine gute Polymermorphologie garantiert. Zudem war ein Verfahren zur Herstellung dieses Katalysatorsystems zu entwickeln, das es ermöglicht die Aktivierung des Katalysatorsystems wahlweise vor dem Einschleusen oder aber erst im Polymerisationsautoklav durchzuführen.The object was to provide a catalyst system which avoids the disadvantages of the prior art and nevertheless guarantees high polymerization activities and good polymer morphology. In addition, a process for producing this catalyst system had to be developed This enables the activation of the catalyst system either before the introduction or only in the polymerization autoclave.

Das stöchiometrische Verhältnis an Metallocenverbindung der Formel (VI) und einer Organometallverbindung der (V) beträgt 100 : 1 bis 10-4 : 1. Vorzugsweise beträgt das Verhältnis 1 : 1 bis 10"2 : 1. Das modifizierte Trägermaterial kann entweder direkt im Polymerisationsreaktor oder in einem Reaktionskolben in einem oben genannten Lösemittel vorgelegt werden. Anschließend erfolgt die Zugabe der Mischung aus einer Metallocenverbindung der Formel (VI) und einer Organometallverbindung der Formel (V). Optional kann aber auch eine oder mehrere Metallocenverbindungen der Formel (VI) ohne vorherige Zugabe einer Organometallverbindung der Formel (V) zu dem modifizieten Trägermaterial gegeben werden.

The amount of one equivalent of a Lewis base of the formula (I) with one equivalent of a cocatalytically active compound which is synthesized according to the formula (II) is particularly preferred. The reaction product of this reaction is a metallocenium-forming compound that is covalently attached to the carrier material. It is referred to below as a modified carrier material. The reaction solution is then filtered and washed with one of the solvents mentioned above. The modified carrier material is then dried in a high vacuum. After drying, the modified carrier material can be resuspended and treated with a compound of the formula (V). The compound of formula (V) can also be added before the filtration and drying of the modified carrier material. The application of one or more metallocene compounds, preferably of the formula (VI) and one or more organometallic compounds of the formula (V), to the modified support material is preferably such that one or more metallocene compounds of the formula (VI) are dissolved or suspended in a solvent described above and then one or more compounds of the formula (V), which is preferably also dissolved or suspended, are reacted.

Dadurch wird verhindert, daß beim Einschleusen des luftempfindlichen Katalysators zum Teil Zersetzung eintritt.However, it can also be used resuspended for the polymerization after removal of the solvent. The advantage of this activation method is that it offers the option of letting the polymerization-active catalyst system arise only in the reactor. This prevents partial decomposition when the air-sensitive catalyst is introduced.
