PROBLEM TO BE SOLVED: To provide a catalyst constituent for addition polymerization after preliminary polymerization, which is scarce with fine powder, an addition polymerization catalyst comprising the same, and a method for producing an addition polymer using the same.SOLUTION: The catalyst constituent for addition polymerization after preliminary polymerization is formed by preliminarily polymerizing an olefin using a primary catalyst obtained by contacting a transition metal compound (A), a modified particle (B) obtained by contacting ML(a), RTH (b), RTH(c) and a particle (d), and an electron-donating compound (C) wherein Mrepresents a typical metal atom belonging to group 1, 2, 12, 14 or 15, m represents the valency of M, Lrepresents a hydrogen atom, a halogen atom or a hydrocarbon group, Rrepresents an electron attracting group or a group containing an electron attracting group, Rrepresents a hydrocarbon group or a halogenated hydrocarbon group, T represents an atom belonging to a group 15 or 16, and t represents a valence of T. |
