✦ Synopsis

This paper presents part of a comprehensive study of the ultrasonic degradation of polystyrene solutions. The efficiency of the process with changing concentration was studied in toluene and methyl butyrate and was found to decrease at higher concentration. In addition, degradations were performed in 13 solvents and the variations correlated in terms of the volatility and thermodynamic parameters of the solvent. The results are explained in terms of a mechanism involving shear forces generated around collapsing cavitation bubbles.

Recent reports by Nakano and Minoura',\* have claimed that the mechanical degradation of high polymers in solution at low concentrations is enhanced if the polymer is dissolved in a thermodynamically "good" solvent. The minimum concentration used in their study (c = 0.04%) gave solutions
