  • Patent number: 8471013
    Abstract: The present invention provides a process for reacting between a phenol derivative and an aromatic substrate under phenolate forming conditions comprising the following steps: (a) reacting a phenol derivative with a base in a polar organic solvent to obtain a phenolate salt, wherein water is removed form the reaction mixture during the reaction, (b) adding the aromatic substrate to the reaction mixture obtained in step (a), (c) heating the reaction mixture of step (b) to a temperature in the range of 80° to 1300° C., preferably, 90° to 1000° C. for 2 to 7 hours to obtain a phenoxy substituted aromatic substrate, (d) removing the solvent from the mixture of step (c) and optionally further isolating an purifying the phenoxy substituted aromatic substrate. Optionally, the removal of water during step (a) is in conjunction with partial removal of the organic solvent.

  • Patent number: 8378044
    Abstract: 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.
