“…Polymerization reactions were performed in a glass reactor rinsed with 100 mL of a 0.04 mol/L solution of Al(iBu) 3 in hexane prior to use. Under argon atmosphere, the proper amounts of toluene and MAO solution were sequentially introduced, and then the system was saturated with ethylene.…”

“…Hierzu gehören z. B. comonomerreiche Ethylen-und Propylencopolymerisate mit a-Olefinen, Cycloolefincopolymere sowie gezielt eingestellte stereoreguläre Polypropylene [1][2][3] . Die mittels neuer Metallocen-Katalysatoren herstellbaren Ethylenpolymerisate weisen strukturell gegenüber den mit üblichen Ziegler-Natta-Katalysatoren hergestellten Polymeren wie HDPE oder LLDPE insbesondere eine sehr enge Molmassenverteilung und eine hohe Einheit-* Korrespondenzautor.…”

“…Chain transfer to aluminum, monomer, and hydrogen may also occur. 5,7 However in order to achieve a high catalyst activity, extremely high aluminum to metal ratios of between 1000-15000:1 is required. Such ratios are unacceptable in terms of cost and the amount of residues in the resulting polymer.…”

“…Several reviews on the subject have been published in recent years. [2][3][4][5][6] It is well established that the 14-e -cationic metallocene, [Cp 2 MR] + , is the active species. 5,[7][8] The most widely accepted model of polymerization mechanism is that proposed by Cosee-Arlman.…”
