Procedure
Separately, 0.49 g (5 mmol) of amidosulfuric acid and 0.51 g (5 mmol) of triethylamine were added to 3 mL of dichloromethane to form amidosulfuric acid triethylamine salt. The formed salt was slowly dripped into the above polymer solution under a nitrogen atmosphere and mixed for 3 hours with stirring. The resulting solution was poured into 400 mL of dichloromethane. The formed precipitates were filtered and washed with dichloromethane, and then dried at 50° C. overnight under reduced pressure. As a result, 0.32 g of yellow powder was obtained for a yield of 81%.
