## Abstract The internal friction and the dynamic modulus of isotactic polypropylene samples subject to varying degrees of pile irradiation have been studied at low audio frequencies and over the temperature range from 100ยฐK. to over 400ยฐK. The radiation dosages used varied from 5.4 ร 10^17^ to 14
