The present invention relates to an olefin polymer having a narrow molecular weight distribution and having a specific molecular weight, an olefin polymer having a functional group introduced at its end, a tapered polymer containing a segment in which the monomer composition is continuously changed in the polymer chain, an olefin polymer having other segments bonded thereto, and It provides a manufacturing method. The olefin polymer of this invention is a C2-C20 olefin polymer, a number average molecular weight is 500 or more, and Mw / Mn is 1.5 or less. The manufacturing method of an olefin polymer is manufactured by superposing | polymerizing a C2-C20 olefin in presence of the catalyst for olefin polymerization which becomes a transition metal compound represented, for example by following formula (I).n n n L m MX n ... (I)n n n (Wherein M is a transition metal atom of Groups 3 to 11 of the periodic table, m is 1 to 5, n is a number satisfying the valence of M, and L is a ligand that coordinates to the central metal M, Is a ligand having a hetero atom which does not have a direct bond, and X is a halogen atom, a hydrocarbon group, etc.) |
