PROBLEM TO BE SOLVED: To provide an olefin polymer having a branched structure and a narrow molecular weight distribution or an olefin copolymer having a branched structure and a narrow molecular weight distribution and a narrow composition distribution with an excellent polymer yield per unit catalyst weight. Provided is a method for producing a coalescence. SOLUTION: A periodic table 10 represented by a general formula LMX 2 is provided. A method for polymerizing an olefin using a compound of a group transition metal element, for example, 1,1'-bis (diphenylphosphino) ferrocene nickel dichloride as a catalyst. In the general formula, L is a specific bidentate chelate ligand, X is a hydrogen atom, or a monovalent ligand selected from the group bonding to M by an element of Groups 14 to 17 of the periodic table, and M is a periodic Table 10 It is a transition metal element selected from the group. |
