Supported metallocene catalysts
CATTECH, 2000Single-site olefin polymerization catalysts have been researched extensively and are now achieving wide acceptance in the polyolefin industry. To achieve commercial significance in the majority of today's commercial processes, these soluble catalysts must be immobilized on a carrier.

Heterogeneous Metallocene Catalysts
1995Copolymerizations of olefins were carried out with the SiO2-, AI2O3- and MgCl2-supported Et[IndH4]2ZrCl2 catalysts combined with AIR3 as cocatalyst and the results were compared with those obtained previously in the presence of homogeneous Et[IndH4]2ZrCl2-MAO catalyst.

Heterogenization of Metallocene Catalysts for Alkene Polymerization
Angewandte Chemie International Edition, 1999Beyond mere convenience: In large-scale industrial processes for alkene polymerization the essentially homogeneous metallocene/activator catalyst systems are heterogenized (example shown) to improve polymer properties. New mesoporous and organic catalyst supports and their application in this field of catalysis are described.

“Oscillating” Metallocene Catalysts: What Stops the Oscillation?
Journal of the American Chemical Society, 2003The 150 MHz (13)C NMR microstructural analysis of polypropylene samples produced with two representative "oscillating" metallocene catalysts of largely different steric hindrance, namely [(2-(3,5-di-tert-butyl-4-methoxyphenyl)indenyl)(2)ZrP](+) and [(2-phenylindenyl)(2)ZrP](+) (P = polymeryl), and the implications on the origin of the stereocontrol are
