Cover Picture: The Ethylene Polymerization with Ziegler Catalysts: Fifty Years after the Discovery (Angew. Chem. Int. Ed. 41/2003)

42_41/2003Fifty years ago Karl Ziegler and co-workers discovered the now-famous process for the catalytic production of polyethylene at moderate temperatures and pressures. The cover of the patent gives November 18, 1953 as the priority date. Today, 50 years on, as a result of highly active catalysts and a detailed understanding of the system on all scales, it is still an extremely viable process. In his Review on page 5010 ff. L. L. Böhm describes the current industrial process based on Ziegler catalysts.
