Supported Metallocene Catalysts

CATTECH, 2000
Single-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.

“Oscillating” Metallocene Catalysts: How Do They Oscillate?

Angewandte Chemie International Edition, 2002
Based on the results of a series of propylene polymns. using oscillating metallocene catalysts of type [(2-Ar-indenyl)2ZrCl2] (Ar = C6H5 or 3,5-(t-Bu)2-4-MeO-C6H2) with various cocatalysts (MAO, TIBAl), the oscillating behavior of the zirconocenes is discussed with respect to the rac/meso stereochem. outcome of the obtained polypropylenes.
