Alumoxanes alternative to MAO: Synthesis and characterization4-trimethylpentyl). (TIOA). Alumoxanes were prepared by reacting TIOA and H.O with different molar ratios. .H NMR spectra of these products are characterized by the presence of broad bands and of resolved multiplets. Their relative amount in the region between 1.9 and 2.5 ppm was identified as the “

New C1-Symmetric Metallocenes for the Polymerization of Olefins) [PhMe.PenFlu)]ZrCl., were compared. The zirconocene (III) is more stereorigid than (I) and (II) and, therefore, has special properties. At a polymerization temperature of 30 °C, (I) in combination with MAO exhibits the highest activity of 7500 kg PP/(mol Zrh*c.), which is about 5 times higher than

New Catalyst Concepts for the Polymerization of Ethylene with Metallocenesium tetrakis(pentafluorophenyl)borate (Me.PhNH·B(C.F.).)/triisobutylaluminum (i-Bu.Al) or methylaluminoxane (MAO) produced a high molecular weight polyethylene with a high activity at high temperatures. The molecular weight of the polyethylene was significantly decreased with an increase in the conc

These reports present a wide range of findings from the research carried out in a variety of activities by large governmental organizations as well as by small private groups and individuals. The reader thus will find a large collection of valuable and interesting
