Substituted pyridyl amine catalysts and processes for polymerizing and polymers

A catalyst for the production of a polymer comprising at least one activator and a metal-ligand complex characterized by the following formula:

• wherein R1 is selected from the group consisting of alkyl, substituted alkyl, cycloalkyl, substituted cycloalkyl, heteroalkyl, substituted heteroalkyl, heterocycloalkyl, substituted heterocycloalkyl, aryl, substituted aryl, heteroaryl, substituted heteroaryl and combinations thereof;
• T is —CR2R3— and R2 are R3 are independently selected from the group consisting of hydrogen, alkyl, substituted alkyl, cycloalkyl, substituted cycloalkyl, heteroalkyl, substituted heteroalkyl, heterocycloalkyl, substituted heterocycloalkyl, aryl, substituted aryl, heteroaryl, substituted heteroaryl, alkoxyl, aryloxyl, silyl, boryl, phosphino, amino, thio, seleno, halide, nitro, and combinations thereof;
• R4, R5, R6 and R7 are each independently selected from the group consisting of hydrogen, alkyl, substituted alkyl, cycloalkyl, substituted cycloalkyl, heteroalkyl, substituted heteroalkyl, heterocycloalkyl, substituted heterocycloalkyl, aryl, substituted aryl, heteroaryl, substituted heteroaryl, alkoxyl, aryloxyl, silyl, boryl, phosphino, amino, thio, seleno, halide, nitro, and combinations thereof;
• and optionally, any combination of R1, R2, R3, R4, R5, or R4 may be joined together in a ring structure;
• provided that either R3 or R7 is selected only from the group consisting of aryl, substituted aryl, heteroaryl and substituted heteroaryl;
