Process for the preparation of a catalyst support in which a hydrophilic, macroporous, disperse aluminum oxide, silicon oxide, titanium oxide or zirconium oxide or their mixtures or mixed oxides is dried at 110 to 800 ° C., then reacted with an aluminoxane and then with multifunctional organic crosslinking agents. In a further step, the catalyst support can be mixed with a reaction product of metallocenes and activators, a supported metallocene catalyst being obtained which is used in particular for the polymerization of olefins. |
