Abstract
The invention relates to a metallocene complex, I (M = metal selected from lanthanides or transition metals from group 3, 4, 5 or 6 of the Periodic System of the Elements; Q = anionic ligand to M, k is the no. of Q groups and equals the valence of M minus 2, R = bridging group contg. at least one carbon atom bonded to the indenyl moiety at 2-position; R1, R2, R3, R4 = each independently chosen from the group consisting of H, halogen, and C1-20 hydrocarbyl group, and wherein at least one of R1 and R2 is not H, and at least one of R3 and R4 is not H). The invention also relates to a catalyst comprising the metallocene complex, to a process for making polyolefins and to the use of the polyolefins for making articles.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
