Description of the Related Art As a catalyst for producing an olefin polymer, for example, an ethylene polymer or an ethylene / α-olefin copolymer, a so-called Ziegler catalyst comprising a titanium compound and an organoaluminum compound has been known. I have. However, the olefin polymer obtained with the catalyst generally has a wide molecular weight distribution and a wide composition distribution, and particularly has a wide composition distribution, and thus has poor surface non-adhesiveness and transparency.
