ИСТИНА

The invention relates to a metallocene complex (1) according to formula (I)Wherein M is a metal selected from the group consisting of lanthanides or transition metals from group 3, 4, 5 or 6 of the periodic system of the elements, Q is an anionic ligand of M, k is the number of Q groups and is equal to the valence of M minus 2, R is a bridging group containing at least one carbon atom and is bonded at the 2-position of the indenyl moiety, R is a group having at least one carbon atom1、R2、R3And R4Each independently selected from the group consisting of H, halogen atoms and C1-C20 hydrocarbyl groups, and wherein R is1And R2Is not H, and R3And R4Is not H. The invention also relates to a catalyst comprising said metallocene complex, a process for the manufacture of a polyolefin and the use of said polyolefin for the manufacture of an article.
