Embodiment 1
[0107] 818 g of methanesulfonic acid and 82 g of phosphorus pentoxide were charged into a four-necked separable flask equipped with a nitrogen introduction tube, a thermometer, a reflux cooler, and a stirring device, and stirred at room temperature under a nitrogen atmosphere for 20 hours. Then, 2.0 g of isophthalic acid and 40.2 g of diphenyl ether were injected|thrown-in, and it heated up to 60 degreeC, and made it react for 10 hours. Then, 57.9 g of 4,4'-oxobisbenzoic acid was added, and further reacted for 40 hours. After cooling to room temperature, the reaction solution was poured into vigorously stirred methanol to precipitate a polymer and then filtered. Furthermore, the polymer was washed twice each with methanol and ion-exchanged water. Then, the polymer was dried at 180° C. under vacuum for 10 hours. When the reduced viscosity was measured, it was 1.1 dl / g, and it was confirmed that the PAEK resin described in Example 1 was obtained.

Embodiment 2
[0110] 818 g of methanesulfonic acid and 82 g of phosphorus pentoxide were charged into a four-necked separable flask equipped with a nitrogen introduction tube, a thermometer, a reflux cooler, and a stirring device, and stirred at room temperature under a nitrogen atmosphere for 20 hours. Then, 4.0 g of isophthalic acid and 40.6 g of diphenyl ether were injected|thrown-in, and it heated up to 60 degreeC, and made it react for 10 hours. Then, 55.4 g of 4,4'-oxobisbenzoic acid was added, and further reacted for 40 hours. After cooling to room temperature, the reaction solution was poured into vigorously stirred methanol to precipitate a polymer and then filtered. Furthermore, the polymer was washed twice each with methanol and ion-exchanged water. Then, the polymer was dried at 180° C. under vacuum for 10 hours. When the reduced viscosity was measured, it was 1.2 dl / g, and it was confirmed that the PAEK resin described in Example 2 was obtained.

Embodiment 3
[0113] 818 g of methanesulfonic acid and 82 g of phosphorus pentoxide were charged into a four-necked separable flask equipped with a nitrogen introduction tube, a thermometer, a reflux cooler, and a stirring device, and stirred at room temperature under a nitrogen atmosphere for 20 hours. Thereafter, 8.1 g of isophthalic acid and 41.5 g of diphenyl ether were charged, and the temperature was raised to 60° C., followed by reaction for 10 hours. Then, 50.4 g of 4,4'-oxobisbenzoic acid was added, and further reacted for 40 hours. After cooling to room temperature, the reaction solution was poured into vigorously stirred methanol to precipitate a polymer and then filtered. Furthermore, the polymer was washed twice each with methanol and ion-exchanged water. Then, the polymer was dried at 180° C. under vacuum for 10 hours. When the reduced viscosity was measured, it was 1.2 dl / g, and it was confirmed that the PAEK resin described in Example 3 was obtained.
