Kinetics of sonodegradation of poly(acrylic acid co acrylamide) hydrogels by viscometry

Prolonged exposure to high-energy ultrasonic waves depolymerizes macromolecules in solutions and produces a permanent reduction in viscosity. Different factors affect theefficiency of this process[1-3]. A method of viscometry was used to study the degradation behavior of the hydrogel.Kinetic analysis of the polymer degradation process has been studied. A detailed degradation mechanism has been proposed including chain scission.
