20130267671 | LIVING RADICAL POLYMERIZATION METHOD - Provided is a low-cost, highly active, environmentally friendly living radical polymerization method which does not require a radical initiator. Even if a catalyst is not used, a living radical polymerization method can be conducted by controlling the amount of the oxygen in the gaseous phase in the reaction vessel within a suitable range. A monomer having a radical-reactive unsaturated bond can be subjected to a radical polymerization reaction to obtain a polymer having narrow molecular weight distribution. The cost of the living radical polymerization can be remarkably reduced. The present invention eliminates the disadvantages of the conventional catalysts such as toxicity, low solubility, coloring/odor and the like, and is significantly more environmentally friendly and economically efficient than conventional living radical polymerization methods. | 10-10-2013 |

20100298499 | NOVEL LIVING RADICAL POLYMERIZATION METHOD USING A PHOSPHORUS COMPOUND OR NITROGEN COMPOUND AS A CATALYST - A highly active and environment-friendly catalyst for use in a living radical polymerization is provided. A catalyst for use in a living radical polymerization method is provided. The catalyst comprises a central element, which is selected from nitrogen and phosphorus, and at least one halogen atom, which is bound to the central element. A monomer having a radical reactive unsaturated bond is subjected to a radical polymerization reaction in the presence of the catalyst, thereby it is possible to obtain a polymer having narrow molecular weight distribution. The present invention has the merits such as low toxicity of the catalyst, a small amount of the catalyst being required, high solubility of the catalyst in the polymerization media, mild reaction conditions, no coloration, no odor (unnecessary post-treatment of molded products). The method of the present invention is more environment-friendly and economical than other living radical polymerization methods. | 11-25-2010 |
20110124832 | NOVEL LIVING RADICAL POLYMERIZATION METHOD USING ALCOHOL AS CATALYST - Provided is a low-cost, environmentally friendly living radical polymerization catalyst having high activity. The catalyst is used for a living radical polymerization method, and contains a central element consisting of oxygen and at least one halogen atom bound to the central element. Furthermore, an alcohol compound can be used as a catalyst precursor. By polymerizing a monomer in the presence of the catalyst, a polymer having narrow molecular weight distribution can be obtained, and the cost of the living radical polymerization can be remarkably reduced. The present invention is significantly more environmentally friendly and economically excellent than conventional living radical polymerization methods, due to advantages of the catalyst such as low toxicity of the catalyst, low amount of the catalyst necessary, high solubility of the catalyst, mild reaction conditions, and no coloration/no odor (which do not require a post-treatment for a molded article), and the like. | 05-26-2011 |
