Alkylphenyl-substituted group 4 metal complexes, catalysts and olefin polymerization process

A metal complex corresponding to the formula:

• 19
• where M is a Group 4 metal that is in the +2, +3 or +4 formal oxidation state;
• RA independently each occurrence is hydrogen, or a hydrocarbyl, halohydrocarbyl, hydrocarbyloxyhydrocarbyl, dihydrocarbylaminohydrocarbyl, dihydrocarbylamino, hydrocarbyloxy, hydrocarbylsilyl, or trihydrocarbylsilylhydrocarbyl group of from 1 to 80 atoms, not counting hydrogen, or further optionally, two or more RA groups may be covalently linked together;
• Z is (RD)2Si=, wherein RD independently each occurrence is C7-20 alkaryl or two RD groups together are alkyl- or polyalkyl-substituted arylene of up to 40 carbons;
• and
• Y is bonded to M and Z and is selected from the group consisting of —O—, —S—, —NR and —PRE—;
• wherein, RE independently each occurrence is hydrogen, or a member selected from hydrocarbyl, hydrocarbyloxy, silyl, halogenated alkyl, halogenated aryl, and combinations thereof, said RE having up to 20 nonhydrogen atoms
• X is an anionic or dianionic ligand group having up to 60 atoms exclusive of the class of ligands that are cyclic, delocalized, π-bound ligand groups;
• X′ independently each occurrence is a neutral ligand having up to 40 atoms;
• p is zero, 1 or 2, and is two less than the formal oxidation state of M when X is an anionic ligand, and when X is a dianionic ligand group, p is 1;
• and
• q is zero, 1 or 2:
