실험 절차

To 31.5 g of 2,4-toluene diisocyanate was added dropwise a solution of 21.5 g of 4,4′-diaminodiphenyl sulfone in 60 mL of MEK at 70° C. with stirring at 300 to 500 rpm over a period of 4 hours, and the reaction was carried out for another 4 hours to obtain a white viscous slurry reaction mixture. Then, the reaction mixture was cooled to 50° C., and 17.1 g of phenol was poured into the reaction mixture to be dissolved therein, after which 0.015 g of triethylamine was added thereto as a catalyst, and the reaction was carried out for 4 hours to obtain a yellow, transparent and viscous reaction mixture. This reaction mixture was freed of the solvent and concentrated under reduced pressure to be solidified, after which the resulting solid was ground and then dried overnight in a vacuum to obtain about 70 g of a urea-urethane composition as light-yellow powder.
