摘要： Provided is a process for preparing copolymers of ethylene with α-olefin. More specifically, provided are transition metal compound being useful as catalyst for preparing those copolymers, a catalyst composition comprising the same, and a process for preparing elastic copolymers of ethylene with α-olefin, having the density of not more than 0.910, which can be adopted to a wide variety of applications including film,, electric wires, and hot-melt adhesives. The catalyst composition is a catalytic system which comprises transition metal catalyst comprising a cyclopentadiene derivative and at least one anionic ligand(s) of aryloxy group with an aryl derivative at ortho-position, and boron or aluminum compound as an activator. Provided is a process for copolymerizing ethylene with α-olefin to produce copolymer having narrow molecular weight distribution and uniform density distribution with the density of not more than 0.910, with high activity and excellent reactivity on higher α-olefin.

摘要： Provided are transition metal catalytic systems for preparing ethylene homopolymers or copolymers of ethylene with α-olefins. More specifically, provided are Group 4 transition metal catalysts, which is characterized in that the Group 4 transition metal catalyst comprises around the Group 4 transition metal a cyclopentadiene derivative, and at least one naphthoxide ligand(s) having aryl substituent(s) that function(s) as an electron donor and serve(s) to stabilize the catalyst system by surrounding an oxygen atom that links the ligand to the transition metal at 2-position, and there is no cross-linkage between the ligands; catalytic systems comprising such transition metal catalyst and aluminoxane cocatalyst or boron compound cocatalyst; and processes for preparing ethylene homopolymers or copolymers of ethylene with α-olefins by using the same.

摘要： Provided are transition metal catalytic systems for preparing ethylene homopolymers or copolymers of ethylene with α-olefins. More specifically, provided are Group 4 transition metal catalysts, which is characterized in that the catalyst comprises around the Group 4 transition metal a cyclopentadiene derivative, and at least one aryloxide ligand(s) having a fluorenyl group or a derivative thereof (which is ready to be substituted at 9-position) that functions as an electron donor and serves to stabilize the catalytic system by surrounding an oxygen atom that links the ligand to the transition metal at ortho-position, and there is no cross-linkage between the ligands; catalytic systems comprising such transition metal catalyst and aluminoxane co- catalyst or boron compound cocatalyst; and processes for preparing ethylene homopolymers or copolymers of ethylene with α-olefins by using the same.
