[0076] The variables in Table 1 have the following meanings: [0077] BF “content of BF in the sample”: calculations were based on the weight of BF added for the conversion of isobutylene, [0078] U conversion in percent, based on isobutylene used, [0079] A yield of polyisobutylene, based on isobutylene used, [0080] Vin proportion of polyisobutylene having vinylidene double bonds in the total polyisobutylene yield, [0081] M average molecular weight (determined by means of gel permeation chromatography), [0082] D dispersity, Example 7 [0083] Continuous Deactivation [0084] The effluent of Example 1 was passed through an insulated connecting pipe at a rate of 2 L/h at from ?25° to ?5° C. continuously from the synthesis reactor through a cooled glass column having a capacity of 100 mL and packed with 45 g of aluminum oxide type PROCATALYSE A.A. 2-5 mm, Grade A (Al O content >93,5%).

Es bedeuten in Tabelle 1: Beispiel 7: Kontinuierliche Desaktivierung Der Austrag aus Beispiel 1 wurde über eine isolierte Verbindungsleitung vom Synthesereaktor mit einer Fließgeschwindigkeit von 2 Liter/h bei -25 bis -5°C kontinuierlich durch eine kühlbare Glaskolonne vom Innenvolumen 100 ml geleitet, die mit 45 g Aluminiumoxid vom Typ PROCATALYSE A.A. 2-5 mm, Grade A (Al O -Anteil >93,5 %) befüllt war.
