| titleOfInvention | Method for producing poly-1,4-phenylene ether |
| abstract | (57) [Summary] (Problems corrected) [Problem] To provide a method for producing poly-1,4-phenylene ether in which a CC bond is not generated and the ortho-position branching is small. A polymerization of a raw material represented by the following formula is performed using any one of (A) to (F) as a transition metal compound catalyst, peroxide as an oxidizing agent, and a free radical trapping agent. (A) A monodentate ligand (N, P, O or S) compound in which C at the α-position is substituted with something other than hydrogen, and (Ligand) / (Transition metal) = 0.01 to 4 (molar ratio). (B) Bidentate ligand (O or S and N, P, O or S) Is a two-coordinated catalyst. (C) A catalyst having at least one transition metal atom per tridentate ligand (N, P, O or S). (D) tetradentate or pentadentate ligand (N, P, O or S) A catalyst having one or more transition metal atoms per one. (E) A catalyst in which the number of transition metal atoms per hexagonal or higher ligand (N, P, O or S) is more than 1/6 of the number of conformations. (F) Meterocene complex catalyst. |
