Procedure

In a stainless steel flask equipped with an agitator, 54.6 grams of water were added, the agitator was turned on, then 25 grams of adipic acid dihydrazide were added. The mixture was agitated for at least 10 minutes until a stable dispersion was formed. 16.4 grams of 2-propanone were then added under mixing. A clear solution formed after a few minutes. Mixing was continued for at least another hour until reaction product precipitated and formed a stable dispersion. 4 grams of AQUAFLOW NLS-200 (rheology additive) were added to the dispersion under agitation.
