Embodiment 1
[0117] 12.38 g of methanesulfonic acid and 2.97 g of phosphorus pentoxide were added to a four-necked separable flask equipped with a nitrogen inlet tube, a thermometer, a reflux cooler, and a stirring device, and the temperature was raised to 100° C., followed by stirring for 4 hours. Then, after cooling to 80°C, 1.02 g of 4,4'-oxidized bisbenzoic acid, 0.09 g of 3-phenoxybenzoic acid, and 1.03 g of 1,4-diphenoxybenzene were added and reacted for 24 hours. Then, after cooling to room temperature, the reaction solution was poured into vigorously stirred methanol to precipitate a polymer. And, the precipitated polymer was filtered.
[0118] The precipitated polymer was further washed twice with methanol. Next, it was washed twice with ion-exchanged water. Then, solid-liquid separation was performed, and the filtered washed cake was dried under vacuum at 180° C. for 10 hours to obtain a polymer.
Embodiment 2
[0120] 12.38 g of methanesulfonic acid and 2.97 g of phosphorus pentoxide were added to a four-necked separable flask equipped with a nitrogen inlet tube, a thermometer, a reflux cooler, and a stirring device, and the temperature was raised to 100° C., followed by stirring for 4 hours. Then, after cooling to 80°C, 1.00 g of 4,4'-oxidized bisbenzoic acid, 0.19 g of 3-phenoxybenzoic acid, and 0.68 g of 1,4-diphenoxybenzene were added and reacted for 24 hours. Then, after cooling to room temperature, the reaction solution was poured into vigorously stirred methanol to precipitate a polymer. And, the precipitated polymer was filtered.
[0121] The precipitated polymer was further washed twice with methanol. Next, it was washed twice with ion-exchanged water. Then, solid-liquid separation was performed, and the filtered washed cake was dried under vacuum at 180° C. for 10 hours to obtain a polymer.
Embodiment 3
[0123] 128.88 g of methanesulfonic acid and 30.93 g of phosphorus pentoxide were added to a four-necked separable flask equipped with a nitrogen inlet tube, a thermometer, a reflux cooler, and a stirring device, and the temperature was raised to 100° C., followed by stirring for 8 hours. Then, after cooling to 80°C, 13.296 g of 4,4'-oxidized bisbenzoic acid, 4.902 g of 3-phenoxybenzoic acid, and 13.506 g of 1,4-diphenoxybenzene were added and reacted for 17 hours. Then, 1.501 g of 1,4-diphenoxybenzene was added, and it was made to react for 23 hours. After cooling to room temperature, the reaction solution was poured into vigorously stirred methanol to precipitate a polymer. And, the precipitated polymer was filtered.
[0124] The precipitated polymer was further washed twice with methanol. Next, it was washed twice with ion-exchanged water. Then, solid-liquid separation was performed, and the filtered washed cake was dried under vacuum at 180° C. for 10 hours to obtain a p...
