発明の名称 (英語) LIVING RADICAL POLYMERIZATION CATALYST, AND POLYMER PRODUCTION METHOD USING SAME UPDATE
発明の概要(英語) Provided are: a living radical polymerization catalyst with which further improvements to safety and cost are exhibited, and which is applicable to various vinyl monomers; and a polymer production method using said living radical polymerization catalyst. This living radical polymerization catalyst includes at least one compound selected from the group consisting of halogenated alkali metal compounds and halogenated alkaline earth metal compounds.
従来技術、競合技術の概要(英語) BACKGROUND ART
In recent years, as one of techniques for a vinyl monomer, living radical polymerization method is known. Living radical polymerization method, generally the molecular weight of the vinyl polymer obtained is relatively easy to control. In addition, the resulting polymer of a vinyl polymer contained in the molecular weight distribution can be narrowed, a weight average molecular weight index (Mw) molecule and the ratio of the number average molecular weight (Mn) (Mw/Mn) is 2 or less of the polymer can be manufactured easily. The molecular weight and the molecular weight distribution, in order to influence the physical properties of the resulting polymer, by living radical polymerization method, the physical properties of the polymer is expected to be controlled.
Conventional, living radical polymerization method, the transition metal complex-based catalyst using a living radical polymerization reactions have been known. Is a catalyst containing a transition metal complex, cu, Ni, Re, Rh, as a central metal of a metal such as Ru, was designed to have a further ligand, complex is required to be obtained. In the case of using the transition metal complex-based catalyst, is a large amount of catalyst used and, further, the catalyst can be removed after the polymerization reaction is difficult. These metals can be, for many toxic, the toxicity of the living body, such as the problem in the environmental aspect there is a possibility. Further, in many cases, the ligand can be, whether the price, is complicated in the synthesis had problems.
In order to solve these problems, the inventors of the present invention, living radical polymerization as a catalyst, such as iodide and to develop compounds of nonmetallic elements (Patent Document 1). The catalyst of the patent document 1, since the catalyst include the transition metal, on which is excellent in safety, expensive by using a ligand since it is not necessary, and is superior in terms of the cost.
However, still, more excellent safety, and, more excellent in terms of the cost, in addition, a variety of vinyl monomers that can be applied to the development of living radical polymerization catalyst been desired earnestly.
