摘要

This invention relates to a novel group 4 transition metal metallocene catalyst compound that is asymmetric having two non-identical indenyl ligands with substitution at R2 having a branched C1-C20 alkyl group, R8 having a linear alkyl group and R4 and R10 having substituted phenyl groups, where at least one of R4 and R10 is a phenyl group substituted at the 3 and 5 position.
