To provide a catalyst constituent for addition polymerization which is capable of producing an addition polymer with a higher polymerization activity, a preliminarily polymerized catalyst constituent for addition polymerization, a catalyst for addition polymerization using the same and method for producing an addition polymer.
The catalyst constituent for addition polymerization is obtained by bringing a modified particle (A) which is obtained by bringing following constituents (a), (b), (c) and (d) into contact with one another, a transition metal compound (B) and further optionally an organo-aluminium compound (C) into contact with one another wherein the transition matal compound is contacted in the state of powder or slurry when the contact takes place, where (a) is a compound expressed by general formula [1]: M1L1m, (b) is a compound expressed by general formula [2]: R1t-1TH, (c) is a compound expressed by general formula [3]: R2t-2TH2 and (d) is a particle. The addition polymer is produced using the preliminarily polymerized catalyst for addition polymerization comprising the preliminarily polymerized catalyst constituent for addition polymerization.
