"Catalytic" Effects of Electrically Charged Polymer Latices on Interionic Reactions

Article abstract of DOI:10.1021/j150601a012

Anionic latices, copolymers of styrene (St) and acrylic acid (AA), were sythesized, and their "catalytic" influences on interionic reactions between oppositely charged species, i.e., reaction between Co(NH3)5Br²⁺ and OH^- and between crystal violet and OH^-, were studied.The latices retarded the reactions, as was the case with anionic macroions.For the former reaction, the latices of higher AA content demonstrated greater retarding effects, indicating that the electrostatic interaction is important.For the latter reaction, on the other hand, there was no difference in the retarding effects of the latices, which implies that the hydrophobic interaction of the latices with the reactant ions plays a more important role than the electrostatic interaction.The activation parameters including the volume of activation were discussed in terms of these interactions.The "catalytic" influences of the latices and linear polymers (sodium polyacrylate and poly(styrenesulfonate)) were also compared.
