Modified particles, carrier prepared therefrom, catalyst component for olefin polymerization prepared therefrom, catalyst for olefin polymerization prepared therefrom, and method for producing olefin polymer

摘要

Modified particles obtained by contacting dry particles(a) with an organometallic compound(b), and subsequently a compound(c) having a functional group containing active hydrogen or a non-proton donative Lewis basic functional group and an electron attractive group; a carrier prepared therefrom; a catalyst component for olefin polymerization prepared therefrom; a catalyst for olefin polymerization comprising said particles(A) and a transition metal compound(B), and optionally an organometallic compound (C) ; and a method for producing an olefin polymer with said catalyst for olefin polymerization. According to the present invention, there is provided a catalyst for polymerizing an olefin giving an olefin polymer excellent in particle properties with a high activity when applied to a slurry polymerization or gas phase polymerization, and a method for producing a olefin polymer using said catalyst.
