Definitions
- the present invention relates to catalyst systems of the Ziegler-Natta type, a process for their preparation and their use for the polymerization of olefins.
- Catalyst systems of the Ziegler-Natta type have been known for a long time. These systems are used in particular for the polymerization of C 2 -C 0 -alk-1-enes and contain, inter alia, compounds of polyvalent titanium, aluminum halides and / or aluminum alkyls and a suitable carrier material.
- the Ziegler-Natta catalysts are usually manufactured in two steps. The titanium-containing solid component is first produced. This is then implemented with the cocatalyst. The polymerization is then carried out using the catalysts thus obtained.
- the present invention was therefore based on the object, starting from the Ziegler-Natta catalyst system described in WO 97/48742 and WO 99/43722, to develop an improved catalyst system which no longer has the disadvantage mentioned above with regard to the formation of deposits in the reactor.

- the carrier material can e.g. under oxidizing or non-oxidizing conditions at temperatures from 100 to 1000 ° C, optionally in the presence of fluorinating agents, such as ammonium hexafluorosilicate, are treated. Among other things, the water and / or OH group content can be varied.
- the carrier material is preferably dried in a vacuum for 1 to 10 hours at 100 to 700 ° C. before being used in the process according to the invention.
- the inorganic metal oxide has an average partial diameter of 5 to 200 ⁇ m, preferably 10 to 100 ⁇ m, and particularly preferably 20 to 70 ⁇ m, an average pore volume of 0.3 to 5 ml / g, in particular of 0, 8 to 3.0 ml / g and particularly preferably 0.8 to 2.5 ml / g, and a specific surface area of 10 to 1000 m 2 / g, in particular 150 to 600 m 2 / g.
