반응 단계
At room temperature, 4.211 g (20 mmol) of trimellitic acid anhydride chloride (TMA) was added to a solution of 4.966 g (20 mmol) of bis(4-aminophenyl) sulfone in 68 ml of NMP, and the resulting mixture was stirred for 2 hours. Then, 2.9 ml (21 mmol) of triethylamine was added at 5° C. and stirred at room temperature for 10 hours. By dropwise adding the reaction mixture into 1.5 liters of water, there was obtained a polyamic acid (TMA/DDSO) as a solid product in a yield of 9.06 g.
