A process for producing a modified particle, which involves the step of contacting with one another compounds (a), (b) and (c) represented by the defined general formulas M 1 L 1 m , R 1 t-1 TH and H 2 O, respectively, and a particle (d), in which M 1 is a metal atom of Group 1, 2, 12, 14 or 15 of the periodic table, m is a valence of M 1 , L 1 is a hydrogen atom, a halogen atom or a hydrocarbon group, which may be the same or different when plural L 1 's exist, R 1 is an electron-withdrawing group or an electron-withdrawing group-containing group, which may be the same or different when plural R 1 's exist, T is a non-metal atom of Group 15 or 16 of the periodic table, and t is a valence of T; and a particle (d), wherein the compound (a) to (c) and the particle (d) are contacted in defined orders and in defined solvents; a carrier comprising said modified particle; a catalyst component for addition polymerization comprising said modified particle; a catalyst for addition polymerization using said catalyst component; and a process for producing an addition polymer using said catalyst. |
