摘要：This disclosure relates to a silica support for a metallocene catalyst used forolefin polymerization, a preparation method thereof, a metallocene catalyst using thesame, and olefin polymer. Specifically, according to the present invention, a silica supportused for preparing a metallocene supported catalyst is treated with a specific

halogenized metal compound, thereby diversifying reaction sites to a cocatalyst whenpreparing a metallocene catalyst, and thus, the molecular weight distribution ofproduced olefin polymer may be much broadened and polymer having high molecularweight may be obtained compared to the existing support, even if the same metallocenecatalyst is supported.
