Abstract
The effect of ultrasound in ethyl methacrylate polymerization and depo lymerization and the chain termination mechanism for ethyl methacrylat e have been studied. Polymerization conversion at 60 degrees C did not depend on energy (80 W) and frequency (35 kHz) of ultrasound applied. In ultrasound depolymerization studies at 20 degrees C the governing termination mechanism was found to be disproportionation and the lower limiting molecular weight was M(n) = 500000.
