Abstract
A metallocene compound of formula (I) Wherein M is an atom of a transition metal; X, is a hydrogen atom, a halogen atom, or a hydrocarbon group optionally containing heteroatoms R1 and R2, equal to or different from each other, are C1-C40 hydrocarbon radical optionally containing heteroatoms; R3 is a C1-C40 hydrocarbon radical optionally containing heteroatoms; R4, R5, R6 and R7, equal to or different from each other, are hydrogen atoms or C1-C40 hydrocarbon radical optionally containing heteroatoms or groups among R4, R5, R6 and R7 can also be joined to form a from 4 to 7 membered ring.
