The effect of initial weight average chain length of addition polymers (polystyrene in benzene) on the degradation parameters is studied in the light of previously developed theories. Results obtained are compared with those of Jellinek and White. An alternative mechanism of ultrasonic degradation of high polymers is suggested. Its mathematical analysis shows that resonant vibration of polymer molecules is possible. Factors affecting mechanism are discussed to account for the discrepancy between theoretical and experimental results.
