Polyelectrolyte complex characterization with isothermal titration calorimetry and colloid titration

Isothermal titration calorimetry (ITC) and colloid titration (CT) were used to characterize aqueous polyelectrolyte complex formation between strong polyelectrolytes, poly(diallyldimethylammonium chloride) and potassium poly(vinyl sulfate) and between weak polyelectrolytes, polyvinylamine (PVAm) and carboxymethyl cellulose (CMC). ITC gives information about the evolution of polyelectrolyte complex properties but does not give good measure of …
