Patent number: 6306791Abstract: Zirconocene compounds with two indenyl ligands linked in the 2 position by means of a two-carbon-atoms divalent bridging group can be suitably used as components of catalysts for the polymerization of olefins. Particularly it is possible to prepare, with high yields, ethylene (co)polymers having low molecular weights and narrow molecular weight distributions, without the need of using considerable amounts of molecular weight regulators, such as hydrogen.Type: GrantFiled: February 28, 2001Date of Patent: October 23, 2001Assignee: Basell Technology Company BVInventors: Colin J. Schaverien, René Ernst, Jan-Dirk van Loon, Tiziano Dall′Occo
