- the present invention relates to a process for producing a catalyst system for the polymerization of olefins.
- the present invention further relates to the catalyst system produced by the process according to the invention and to a process for the polymerization and copolymerization of olefins using the catalyst system according to the invention. 5
- Polymers and copolymers of olefins are of great economic importance because the monomers are easily accessible in large quantities and because the polymers can be varied over a wide range by varying the production process or the processing parameters. Particular attention is paid to the catalyst used in the manufacturing process.
- various types of single-site catalysts are of increasing importance, with central atoms in addition to Zr, for example in metallocene catalysts 5 (H.-H. Brintzinger et al., Angew. Chem. 1995, 107, 1255 ) Ni or Pd (WO 96/23010) or Fe and Co (eg WO 98/27124) have recently been examined in more detail.
- the complexes of Ni, Pd, Fe and Co are also referred to as complexes of late transition metals.
- Metallocene catalysts have disadvantages for large-scale use.
- the catalysts are very sensitive to impurities in the monomers available on an industrial scale, in the process gas and in the solvents used. Moisture and oxygen as well as CO are to be mentioned as disturbing impurities.
- the price for Zr as the central metal of the technically important zirconocenes is very high.
- the catalysts activated with aluminoxanes are usually metered in a polymerization-active manner into the current process, for example gas phase, solution, suspension or bulk polymerization processes, and can lead to blockages, in particular in the metering lines.
- Aluminoxanes are molecularly undefined substances whose ability to activate transition metal complexes strongly depends on the manufacturing process and impurities.
- the storage temperature and the storage time also play a role. Quality control is difficult.
- Aluminoxanes must always be stored refrigerated, because otherwise they tend to gel.
- Aluminoxane gels are unsuitable as cocatalysts.
- Aluminoxanes are marketed as solutions, so a lot of otherwise worthless solvent has to be transported.
- Aluminoxanes especially those with C 1 -C 4 -alkyl radicals, and their solutions are pyrophoric and require increased security.
- WO 98/27124 and WO 98/30612 relate to the polymerization of ethylene and propylene, in which case an Fe or Co complex of a tridentate pyridyldiimine ligand is first contacted with ethylene or propylene or another monomer; then MAO or an activator with a defined structure are added and finally an aluminum alkyl.
- the procedure is such that a complex of a late transition metal, in this case an Fe or Co complex in the presence of ethylene, is first mixed with aluminum trialkyl and then with a strong Lewis acid such as B (C 6 Fs) 3 .
- B (C 6 Fs) 3 a strong Lewis acid
- WO 99/12981 relates to catalyst systems with tridentate pyridyldiimine ligands as catalysts for the polymerization of
- Example 29 shows the polymerization with a molecularly defined activator, especially a tetrakispentafluorophenylborate, and (trimethylsilylmethyl) magnesium chloride as the alkylating agent.
- the trimethylsilylmethyl anion is very sterically demanding and must be chosen because it can prevent reductive elimination of the alkyl groups * on the late transition metal.
