Abstract: The method for oligomerizing olefin according to the present disclosure is a method for oligomerizing olefin using an oligomerization catalyst system and includes deteriorating the activity of the oligomerization catalyst system by injecting a deactivator in a latter part of a multimerization reaction of olefin. The deactivator may include an additive for polymer containing at least one functional group selected from the group consisting of a hydroxyl group, an amine group and an amide group. According to the oligomerizing method, the isomer of 1-hexene and/or 1-octene and alpha-olefins with C10 to C40 may be decreased via the restraint of the additional side reaction of a product. Since the deactivator is an additive for enhancing the physical properties of a polymer, a separating process thereof is not required, thereby improving economic feasibility and productivity.

Abstract: This disclosure relates to a silica support for a metallocene catalyst used for olefin polymerization, a preparation method thereof, a metallocene catalyst using the same, and olefin polymer. Specifically, according to the present invention, a silica support used for preparing a metallocene supported catalyst is treated with a specific halogenized metal compound, thereby diversifying reaction sites to a cocatalyst when preparing a metallocene catalyst, and thus, the molecular weight distribution of produced olefin polymer may be much broadened and polymer having high molecular weight may be obtained compared to the existing support, even if the same metallocene catalyst is supported.
