Abstract: A method of producing a polymer including a polymerization step of obtaining a polymer by controlled radical polymerization of a monomer (Y) in the presence of an organic compound (A) represented by formula (I) and its constituents and a radical generator (B), where a molar ratio (B/A) of (B) to (A) is from 0.5 to 20. The production method allows synthesis of a highly safe polymer with a high molecular weight while precisely controlling the molecular sequence and the end structure. In addition, the production method is low in toxicity, environmentally friendly, and operated at low costs.
