Abstract:
1. An organometallic composition which can be used as activating component in a metallocene catalyst for the (co)polymerization of α-olefins, comprising the following three components in contact with one another: (A) a fluorinated organic compound, comprising at least one di-unsaturated cycle with 5 or 6 carbon atoms, having the following formula (I): wherein: H is a weakly acid hydrogen atom, each R on the condition that at least two of the groups R “m” can have the values of 0 or 1; (B) an organometallic compound sufficiently basic to react with the acid hydrogen of the above compound having formula (I) in an acid/base reaction; (C) a polar aprotic organic compound, not containing metallic atoms, having a dielectric constant, in the pure state, equal to or greater than 2, and a weak coordinating capacity corresponding to a donicity DN not greater than 15 kcal/moles.
