Activating composition of metallocene complexes in the catalysis of (co)polymerization processes of olefins

摘要

Organo-metallic composition without boron, comprising an extensively fluorinated organic compound, stable to the air, having a di-unsaturated cycle with five or six carbon atoms, and an alkyl derivative of magnesium or, preferably, of aluminum. Said composition can be used as activator of a metallocene complex of group 4 of the periodic table of elements to form a catalyst with a high activity and low metal content for the polymerization of alpha -olefins.
