This invention relates to 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:
1
wherein M is selected from groups 3-11 of the periodic table;
2
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.
本发明涉及一种聚合方法,包括接触至少一种烯烃单体、至少一种极性单体、一个可选的活化剂和一个催化剂化合物,该化合物由以下公式表示:1其中M选自周期表的3-11组;2L1表示正离子配体,L2表示中性配体,a为大于或等于1的整数;b大于或等于0;c大于或等于1;E为氮或磷,Ar0为芳烃,R1-R4各自独立地选自氢、烃基、取代烃基或功能基团,但提供R3和R4不形成萘环,N为氮,O为氧。
