Benzazole and pseudoindole diamido transition metal complexes and use thereof in olefin polymerization

A catalyst system comprising:

• at least one activator;
• and
• a transition metal complex having a formula of:
• wherein:
• M is a transition metal;
• E is NR2, CR3R4, O, S, or SiR5R6;
• Q is optional substitution selected from the group consisting of a hydrocarbyl group, a heteroatom substituent, and any combination thereof;
• p is an integer ranging from 0 to 3;
• L is an optional neutral ligand, with two L optionally being joined together to form a bidentate neutral ligand;
• m is an integer ranging from 0 to 3;
• X is an anionic leaving group, with two X optionally being joined together to form a dianionic leaving group;
• n is 1 or 2;
• wherein a sum of m+n is 4 or less;
• J is a linker group contributing two or three atoms that are located within a first chelate ring;
• R1 and R1′ are independently selected from the group consisting of a hydrocarbyl group and a trihydrocarbylsilyl group;
• R2 is a hydrocarbyl group;
• R3 and R4 are independently selected from the group consisting of H, a hydrocarbyl group, and a trihydrocarbylsilyl group;
• and
• R5 and R6 are independently a hydrocarbyl group.
