Interpolyelectrolyte reactions in solutions of Polycarboxybetaines

Potentiometry, turbidimetry, and fluorescence spectroscopy were used to reveal the utility of different polycarboxybetaines (PCB) as positively charged components of polyelectrolyte complexes. The results indicated that PCB interacts efficiently with sodium poly(styrenesulfonate) forming polyelectrolyte complex with pH-controlled solubility, and this could be important in the development of bioseparation techniques.
