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.
本发明涉及通过聚合方法制备的共聚物,该方法包括接触至少一种烯烃单体、至少一种极性单体、可选的活化剂和催化剂化合物。该催化剂化合物的化学式为:其中M从周期表的3-11组中选择;L1表示正离子配体,L2表示中性配体,a是大于等于1的整数;b大于等于0;c大于等于1;E是氮或磷,Ar0是芳烃,R1-R4分别选择自氢、烃基、取代烃基或功能基,但R3和R4不形成萘环,N是氮,O是氧。
