Beschreibung
Zusammenfassung:	The present invention relates to metallocenes, wherein the two cyclopentadienyl rings are connected to each other by a single carbon atom characterized by the following general formula III where each A, equal to or different from each other, is selected from the group consisting of: hydrogen, OR , NRR , or SR ; and to compounds of formula IV wherein each B, equal to or different from each other, is selected from the group consisting of: OH, NRH or SH, obtained by hydrolizing the corresponding oxygen, nitrogen or sulfur containing groups from compounds of formula III. These compounds are used as active catalyst components in the polymerization of olefins.
