Disclosed is a catalyst for living radical polymerization, which provides a catalyst containing a central element consisting of carbon and at least one halogen atom that is bonded to said central element. In addition, a hydrocarbon compound can be used as a catalyst precursor. By causing a monomer with a radical-reactive unsaturated bond to have a radical polymerization reaction in the presence of this catalyst, a polymer with a narrow molecular weight distribution can be obtained, dramatically decreasing the cost of living radical polymerization. The present invention has the advantages of the catalyst having low toxicity, low usage amount, high solubility, and moderate reaction conditions, and being colorless and odorless (not requiring post-treatment of the molded goods), etc., and is markedly both environmentally and economically superior to past living radical polymerization methods. |
