• This research studied the mechanical effects of various frequencies by the degradation of Polyethylene oxide and Polystyrene at different solvents, concentration. In order to exclude the influence of sonochemical apparatus, different types were used. The power delivered into solution was set at the same (5W). In water solution, t-BuOH was used as a radical scavenger to suppress the chemical effects. The results showed that there is nearly the same trend in degradation of polymer despite of the type of polymer or the solvents: the mechanical effects decreases as the frequency increases. The maximum and minimum mechanical effects are at around 40 kHz and 500 kHz, respectively.
