摘要

PROBLEM TO BE SOLVED: To provide a method for performing polymerization, capable of giving a preliminary polymerized catalytic component for the addition polymerization, containing less fine powder.;SOLUTION: This method for performing the preliminary polymerization of an addition polymerizable monomer includes the following processes: (1) a process of forming a mixture by mixing solvent for the polymerization with (D) an organic compound expressed by formula [2]; (2) a process of performing the preliminary polymerization of the monomer in the mixture in the presence of a catalyst formed by making a contact of (A) a compound selected from a transition metal compound expressed by formula [1] and its μ-oxo type transition metal compound dimer with (B) an activator, wherein formula [1] is L¹_aM¹X¹_b and formula [2] is R¹C(=O)NR²₂.;COPYRIGHT: (C)2013,JPO&INPIT
