PROBLEM TO BE SOLVED: To produce a polymer by a living radical polymerization method by reducing impurities composed of a transition metal and its ligand used as a polymerization activator, and coloring or mechanically forming a film molded product or the like. Deterioration of mechanical properties, poor crosslinking and migration Produce polymers without problems such as contamination. SOLUTION: a) a step of performing a polymerization reaction using a monomer, a transition metal and its ligand, and a polymerization initiator to form a polymer; and b) a transition metal contained in the polymer and the same. A step of removing the ligand in a state where the viscosity is 100 Pa ยท s or less, and the step b) is a step of b1) a preceding step of removing the transition metal insoluble in the polymer and the ligand, b2) A method for producing a polymer, comprising: a step of removing a transition metal dissolved in the polymer and a ligand thereof. |
