Procedure
In addition, as a further difference, feed stream 1 was metered in at a uniform rate over 5 minutes rather than 40 minutes, and feed stream 2 was metered in at a uniform rate over 125 minutes rather than 90 minutes. The additions of the 12.0 g of deionized water each took place following the ends of feed streams 1 and 2, and the additions of the aqueous ammonia solution took place at the same distance from the beginning of the reaction as in example 3, and, furthermore, instead of 40.9 g of a 13.2% strength by weight aqueous solution of adipic dihydrazide, 36.4 g of a 2.5% strength by weight aqueous solution of adipic dihydrazide were used.
