This invention discloses a method for producing polyarylene thioether by the catalytic oxidative coupling polymerization of at least one compound selected from the group consisting of diaryl disulfides of general formula (I) and thiophenols of general formula (11), wherein R1 to R12 are each as defined in the specification, by using oxygen in the presence of an acid. According to the above method, the reaction proceeds under very mild conditions; the procedure can be simplified; and the starting material and catalyst an available at extremely low cost. Thus, this method is advantageous industrially.
本发明公开了一种生产聚芳基硫醚的方法,该方法是在酸存在下,利用氧催化至少一种选自通式(I)的二芳基二硫化物和通式(11)的噻吩酚(其中 R1 至 R12 各为本说明书中定义的)所组成的组中的化合物的氧化偶联聚合。根据上述方法,反应在非常温和的条件下进行;程序可以简化;起始材料和催化剂成本极低。因此,这种方法在工业上很有优势。
