摘要： 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. Metallocenes of the following generic structure are disclosed:
