Sulfaguanidine exhibited a maximum in the sedimentation volume‐polymer concentration curve. All suspensions appeared uniform except for the bismuth subnitrate, which exhibited coarse, unsightly floccules. This effect was attributed to an interaction between the anionic polymer and the cationic bismuth subnitrate particles.
