Reaction Conditions

Reaction Steps

20 mmol of triisobutylaluminum (TiBA, 10 ml of a 2 molar solution in heptane) were placed in a dry 10 l autoclave which had been flushed with N2. After addition of 150 mg of antistatic solution (Stadis® 450, Du Pont), 2000 g of liquid propene, 40 g of 1-butene (2% by weight) and 40 g of 1-hexene (2% by weight) were metered in. At room temperature, 905 mg of the supported metallocene catalyst prepared in Example 1 were then blown in via a lock by means of N2. The autoclave was subsequently heated to 60° C. and the mixture was polymerized for 90 minutes at this temperature. After this reaction time had expired, the polymerization was stopped by blowing-off the remaining monomer mixture and the product was discharged via a bottom discharge valve. 543 g of polymer powder were obtained (productivity: 600 g of terpolymer/g of catalyst). The proportion of regioregular ′1-2′-inserted propene units in the terpolymer obtained corresponding to formula (1) is 99.12.
