METHOD FOR PRODUCING AROMATIC COMPOUND POLYMER

摘要

A method for producing an aromatic compound polymer wherein one or more aromatic compounds having two or more hydrogen atoms directly bonded to an aromatic ring is oxidatively polymerized in the presence of an oxidizing agent, characterized in that use is made of a catalyst which consists of a transition metal complex or is prepared from a transition metal complex and an activating agent, and has a parameter P defined by the following formula (A) of 0.50 or more and a parameter Eo defined by the following formula (B) of 0.50[V] or more; P = Af/Ai (A) [wherein Ai represents an absorbance of the local maximum absorption in the absorption band being present in the longest wavelength side in an absorption spectrum obtained in the wavelength region from ultraviolet to near-infrared of 200 nm to 800 nm with respect to a solution containing the above catalyst, and Af represents an absorbance at the same wavelength as that for Ai in an absorption spectrum obtained in the above wavelength region with respect to a solution obtained by the addition of water in an amount of three equivalents relative to a molar number of the metal contained in said catalyst to the above-mentioned solution] E<SUB>0</SUB> = (Epa + Epc)/2 [V] (B) [wherein Epa represents an oxidation side peak potential of the oxidation-reduction potential originated from the transition metal contained in said catalyst in a potential of 0.50[V] or higher on the basis of the oxidation-reduction potential of ferrocene/ferrocenium ion in the case wherein a solution containing said catalyst is measured by cyclic voltammetry, and Epc represents an reduction side peak potential corresponding to Epa, when measured in the same manner as above].
