| 摘要 |
This invention relates to a composition of matter represented by the formula below, and to a polymerization process comprising combining an olefin in the gas or slurry phase with an activator, a support and a compound represented by the following formula:
wherein
M is a group 3 to 14 metal,
each X is independently an anionic leaving group,
n is the oxidation state of M,
m is the formal charge of the YZL ligand,
Y is a group 15 element,
Z is a group 15 element,
L is a group 15 or 16 element,
R 1 and R 2 are independently a C 1 to C 20 hydrocarbon group, a heteroatom containing group, silicon, germanium, tin, lead, phosphorus, a halogen,
R 1 and R 2 may also be interconnected to each other,
R 3 is absent, or is hydrogen, a group 14 atom containing group, a halogen, a heteroatom containing group,
R 4 and R 5 are independently an aryl group, a substituted aryl group, a cyclic alkyl group, a substituted cyclic alkyl group, or multiple ring system,
R 6 and R 7 are independently absent or hydrogen, halogen, a heteroatom or a hydrocarbyl group, or a heteroatom containing group. |
