This invention relates to copolymers produced by a polymerization method comprising contacting at least one olefin monomer, at least one polar monomer, an optional activator, and a catalyst compound represented by the formula:
wherein M is selected from groups 3-11 of the periodic table;
L
1
represents a formal anionic ligand, L
2
represents a formal neutral ligand, a is an integer greater than or equal to 1; b is greater than or equal to 0; c is greater than or equal to 1,
E is nitrogen or phosphorus, Ar
0
is arene, R
1
-R
4
are, each independently, selected from hydrogen, hydrocarbyl, substituted hydrocarbyl or functional group, provided however that R
3
and R
4
do not form a naphthyl ring, N is nitrogen and O is oxygen.
