    摘要： This invention relates to a polymerization process comprising combining an olefin in the gas or slurry phase with a liquid carrier comprising an activator and a compound represented by the following formula: wherein M is a Group 3 to 12 transition metal or a Group 13 or 14 main group metal, each X is independently a leaving group, y is 0 or 1 (when y is 0 group L′ is absent), n is the oxidation state of M, m is 0, −1, −2 or −3, L is a Group 15 or 16 element, L′ is a Group 15 or 16 element or Group 14 containing group, Y is a Group 15 element, Z is a Group 15 element, R1 and R2 are independently a C1 to C20 hydrocarbon group, a heteroatom containing group having up to twenty carbon atoms, silicon, germanium, tin, lead, or phosphorus, R3 is absent or a hydrocarbon group, hydrogen, a halogen, a heteroatom containing group, R4 and R5 are independently an alkyl group, an aryl group, substituted aryl group, a cyclic alkyl group, a substituted cyclic alkyl group, a cyclic aralkyl group, a substituted cyclic aralkyl group or multiple ring system, preferably having up to 20 carbon atoms, R1 and R2 may be interconnected to each other, and/or R4 and R5 may be interconnected to each other, R6 and R7 are independently absent, or hydrogen, an alkyl group, halogen, heteroatom or a hydrocarbyl group, preferably a linear, cyclic or branched alkyl group having 1 to 20 carbon atoms, more preferably absent, and R* is absent, or is hydrogen, a Group 14 atom containing group, a halogen, a heteroatom containing group. This invention further relates to the polymer produced from the above process.
