Procedure

The preparation of the supported catalyst is repeated analogously to Example 1 with the difference that 65 mg (0.15 mmol) of isopropyl (9-fluorenyl)cyclopentadienyl-zirconium dichloride are dissolved in 40 ml of toluene and added dropwise to the suspension of 3.9 g of "MAO on SiO2, type B" in 60 ml of toluene. Analysis of the pale-red filtrate gives a zirconium content of 0.9 mg (corresponding to 4.3 mg of isopropyl-(9-fluorenyl)cyclopentadienylzirconium dichloride). 3 g of free-flowing, violet, supported catalyst containing 20 mg of zirconocene per gram of catalyst are obtained.
