| titleOfInvention | Multi-stage polymerization of olefin |
| abstract | (57) [Problem] To provide a method for producing an ethylene copolymer composition which can produce a film having excellent moldability and excellent transparency and mechanical strength. An olefin multistage polymerization method comprising the following steps [I] and [II]. Step [I] : M 1 L 1 x [b] an organoaluminum oxy compound or the like, [c] in the presence of a catalyst [d-1] supported on a carrier, ethylene and α- A step of producing a copolymer (A) by copolymerizing an olefin; Step [II] : In the presence of (A) obtained in Step [I], the catalyst [d-] supported on M 2 L 2 x or M 3 L 3 x , [b] and [c] 2], and (co) polymerizing ethylene or ethylene and an α-olefin to produce a copolymer (B). [However, M 1 , M 2 and M 3 are Group IVb transition metals, at least two of L 1 are Cp groups or C 1 to C 10 substituted Cp groups, and L 2 is a cross-linked Cp Groups, fewer or two is Cp group having 2-5 a Me or Et group L 3. ] |
