Supported polymerization-catalyst and its use for olefin polymerization

摘要

Supported polymerization catalyst containing the reaction product of a) a catalyst support based on aluminum oxide, silicon oxide, titanium oxide or zirconium oxide and aluminoxanes and polyfunctional organic crosslinkers and b) transition metal salts of groups IV to VIII, and optionally Mg-compounds and electron donor compounds. This catalyst is useful for polymerizing or copolymerizing of olefins.
