1. A process to polymerize olefins comprising:
i) contacting olefins with a catalyst system comprising: 1) support comprising an organoaluminum treated layered silicate and inorganic oxide and 2) bisphenolate compound represented by the Formula (A): wherein each solid line represents a covalent bond and each dashed line represents a coordinative link; wherein M is a group 3, 4, 5 or 6 transition metal; N1 and N2 are nitrogen; O is oxygen; each of X1 and X2 is, independently, a univalent C1 to C20 hydrocarbyl radical, a functional group comprising elements from groups 13 to 17 of the periodic table of the elements, or X1 and X2 join together to form a C4 to C62 cyclic or polycyclic ring structure, provided however when M is trivalent X2 is not present; each R1, R2, R3, R4, R5, R6, R12, R13, R14, R15, R16, and R17 is, independently, hydrogen, a C1 to C40 hydrocarbyl radical, a functional group comprising elements from groups 13 to 17 of the periodic table of the elements, two or more of R1, R2, R3, R4, R5, R6, R12, R13, R14, R15, R16, and R17 independently join together to form a C4 to C62 cyclic or polycyclic ring structure, or a combination thereof; wherein R*1 and R*2 independently comprise a bulky functional group, an electron withdrawing group, or a combination thereof; and Y is a divalent C1 to C20 hydrocarbyl radical. |
