PURPOSE:To form the titled copolymer improved in properties and processability, by reacting an aromatic ether compound with phosgene in the presence of a specified comonomer component. CONSTITUTION:Use is made of, as a comonomer component copolymerizable with diphenyl ether, (i) an aromatic compound of formula I in an amount to provide a molar ratio <=67%, or (ii) an aromatic dicarboxylic dihalide of formula II or III in an amount to provide a molar ratio <=40% (in the formulas, R<17-36> are each H, a halogen, hydrocarbon or alkoxyl, X is a direct bond, O or S, Z is a halogen, and n is 0-3). Namely, diphenyl ether is reacted with the above comonomer component and phosgene is about 1-500pts.wt., per pt. wt. diphenyl ether, organic solvent in the presence of about 0.5-5mol, per mol of the ether, of catalyst to form an aromatic polyether-ketone copolymer. This copolymer has at least 60mol% units represented by formula IV (wherein R<1-8> are each H, a halogen, hydrocarbon or alkoxyl).

In addition, the disadvantages in terms of physical properties are that the Tm of the obtained polymer is as high as JAjc, so a high molding temperature of 1 Ioo°C or higher is required, and the crystallization rate is fast, making it difficult to obtain a homogeneous amorphous sample. In view of the above points, the inventors of the present invention conducted intensive studies, and found that aromatic polyetherketone (side and side) was first converted into a Lewis compound by a reaction between an aromatic ether compound and phosgene. We have found a method for producing it under mild conditions around room temperature in an aprotic organic solvent in the presence of an acid, and at a significantly low cost.
