modified particles, the former institution, resulting polymerisationskatalysatorkomponente and polymerisationskatalysator and processes for the manufacture of olefinpolymeren

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.
