Abstract
A catalyst system including the reaction product of a fluorided support, an activator, and at least a first transition metal catalyst compound; methods of making such catalyst systems, polymerization processes using such catalyst systems, and polymers made therefrom.
Claims47
A catalyst system comprising the reaction product of a fluorided support, an activator, and a catalyst compound represented by Formula I:
- 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, or a univalent C1 to C20 hydrocarbyl radical, a univalent substituted C1 to C20 hydrocarbyl radical, or X1 and X2 join together to form a C4 to C62 cyclic or polycyclic ring structure, provided, that 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, or a substituted C1 to C40 hydrocarbyl radical, optionally, 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;
- 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 hydrocarbylene radical.
