摘要
The interaction of a cationic polymer of sulfonylpiperidinylmethylene hydroxide with anions of sulfophthalein dyes was studied. The formation of ion associates of the polycation with anionic forms of Bromophenol Blue, Phenol Red, and Pyrocatechol Violet of the stoichiometric compositions 1 : 1 and 1 : 2 was found. A procedure for determining this cation was developed with the aim of monitoring the process of Its synthesis.
