Investigating the Effects of Charge Arrangement in Stimuli-Responsive Polyelectrolytes

The transition from self-coacervation to complex coacervation of a series of charge-balanced polyampholyte (PA) and polyelectrolyte (PE) pairs based on the copolymers of methacrylic acid and N-(3-aminopropyl) methacrylamide hydrochloride is described, with focus on the effects of charge distribution on coacervate properties. Turbidimetric pH titration was used to compare the response of different charge-balanced coacervates to changes in pH. At …
