Title
(EN) BRIDGED METALLOCENE COMPOUNDS, PROCESSES FOR THE PREPARATION THEREOF, AND USE THEREOF IN CATALYSTS FOR THE POLYMERIZATION OF OLEFINS

Abstract
(EN)
Metallocene compounds with two indenyl-type ligands linked in the 4 position by means of a divalent bridging group can be suitably used as components of catalysts for the polymerization of olefins. In particular, it is possible to prepare saturated or unsaturated elastomeric copolymers of ethylene characterized by valuable properties, such as low ash content and uniform distribution of the comonomers in the polymer chain.
(FR)
Des métallocènes avec deux ligands du type indényle liés en position 4 par un pont de liaison divalent peuvent être utilisés d'une manière avantageuse comme composants de catalyseurs de polymérisation d'oléfines. En particulier, il est possible de préparer des copolymères élastomères saturés ou insaturés d'éthylène ayant des propriétés très utiles, comme par exemple une teneur faible en cendres et une répartition uniforme des comonomères dans la chaîne polymère.
