Abstract (en)
[origin: WO2017011073A1] This invention relates to novel bridged bis indenyl metallocene catalyst compounds where the bridge is -((R15*)2Si-Si(R15)2)- wherein, each R15 and R15* is identical or different and is a substituted or unsubstituted, branched or unbranched C1-C20 alkyl group, preferably each R15 together do not form a ring, and/or each R15* together do not form a ring, and/or R15 and R15* together do not form a ring. This invention also relates to polymerization processes to produce polymer and to polymer compositions produced by the methods described.
