ABSTRACT:
A catalyst compound of formula I or II:(wherein R1–R11, M, E, T, X, Y, m and n are defined herein). The compound, when combined with a suitable activator, is active for the polymerization of olefins. In an embodiment of combinations of the R1–R7and T groups, these catalysts can engage in weak attractive non-covalent interactions with the polymer chain. In another embodiment, the R1–R11groups in formula II exhibit weak attractive non-covalent interactions with the polymer chain.
