摘要
This paper describes the use of power ultrasound to modify and control the molecular weight of polymers. The effect of experimental conditions on the degradation is illustrated using polystyrene as an example and they are interpreted in terms of a shear mechanism involving the movement of solvent molecules around collapsing cavitation bubbles. The application of the process during polymer synthesis is also illustrated.
