A process for preparing a catalyst support in which a hydrophilic inorganic oxide of an element of main groups 2, 13 or 14 or transition group 4 of the Periodic Table or a mixture or mixed oxide thereof is dried at from 110 to 800° C., subsequently reacted, if desired, with alumioxanes or aluminum alkyls and subsequently reacted simultaneously with aluminoxanes and bisphenol A as a polyfunctional organic crosslinker. In a further stage, the catalyst support can be brought into contact with a polyolefin catalyst, giving a supported polyolefin catalyst which is used, in particular, for the polymerization of olefins.
