A process for producing aromatic polyether ketones and polythioether ketones, which comprises reacting aromatic ethers or thioethers represented by the general formula:
where each of R1 to R12 is a hydrogen atom, a halogen atom, a hydrocarbon group or an alkoxy group, n is an integer of 0 to 5, and X is an oxygen atom or a sulfur atom, with phosgene in aprotic solvent having a dielectric constant of lower than 20 and a dipole moment of lower than 3.0 in the presence of anhydrous halides of metals of Group III in the periodic table as a catalyst.
一种生产芳香族聚醚酮和聚硫醚酮的工艺,它包括使通式所代表的芳香族醚或硫醚反应:
其中 R1 至 R12 各为氢原子、卤素原子、烃基或烷氧基,n 为 0 至 5 的整数,X 为氧原子或硫原子,在介电常数低于 20 和偶极矩低于 3.0 的无水光气溶剂中,以元素周期表中第 III 族金属的卤化物为催化剂进行反应。
