Salenol catalyst

A catalyst system, comprising an activator and a catalyst compound represented by the formula:

• wherein each solid line represents a covalent bond and each dashed line represents a bond having varying degrees of covalency and a varying degree of coordination;
• wherein M is a Group 3, 4, 5 or 6 transition metal;
• wherein N1 and N2 are nitrogen and O1 and O2 are oxygen;
• wherein n is 1 or 2;
• wherein each X is, independently, a univalent C1 to C20 hydrocarbyl radical, a functional group comprising elements from Groups 13-17 of the periodic table of the elements, or where n is 2 each X may join together to form a C4 to C62 cyclic or polycyclic ring structure;
• wherein Y is selected from the group consisting of divalent C1 to C20 hydrocarbyl radicals, divalent functional groups comprising elements from Groups 13-17 of the periodic table of the elements, and combinations thereof;
• and
• wherein each of R1, R2, R3, R4, R5, R6, R7, R8, R9 and R10 is, independently, a hydrogen, a C1-C40 hydrocarbyl radical, a functional group comprising elements from Group 13-17 of the periodic table of the elements, or two or more of R1 to R10 and Y may independently join together to form a C4 to C62 cyclic or polycyclic ring structure.
