Abstract : The propagation of ultrasonic waves through polyelectrolyte solutions gives rise to alternating potential differences (polyelectrolyte vibration potentials) within the solution. A theory for the effect is developed on the basis of the polymer bead model and the earlier theoretical treatment for ionic vibration potentials. Measurements of the polyelectrolyte vibration potentials at 220 kHz were carried out with polyacrylic acid and other polyelectrolytes as a function of concentration of polyelectrolyte, percent neutralization and the nature and concentration of added salts. The agreement between theory and experimental values is quantitative. Polyelectrolyte vibration potentials measurements appear capable of providing information concerning counterion bonding and the volumes of the monomer units within the polymer beads. (Author)
