Patent ID: 8569194

Claim:
A catalyst composition for polymerization of olefins, comprising a) a catalytic metallocene component (A) of the formula (I) wherein: M 1 is a transition metal from the lanthanides or from group 3, 4, 5 or 6 of the periodic system of elements, Q 1 is an activatable ligand to M 1 , k is the number of Q 1 groups and is equal to the valence of M 1 minus 2, R 1 is a bridging group and Z 1 -Z 6 and X 1 -X 4 are substituents, wherein R 1 is bonded to the indenyl group at the 2-position thereof, b) a catalytic Ziegler-Natta type transition metal component (B), c) an activator, and d) support material; wherein a polymer formed using the catalyst composition has a high molecular weight fraction and a low molecular weight fraction, with comonomer predominantly in the high molecular weight fraction.
