Abstract:

A study is made of internal friction in commercial-grade polymethylmethacrylate after γ-ray irradiation with doses between 0 and 200 kGy. The influence of γ-radiation on the α and β relaxations is analyzed. Also, this investigation shows that the structural relaxation a is modified with the irradiation dose. Finally, the results obtained are discussed considering the changes in the molecular structure produced by γ-radiation. © 1996 Eisevier Science Ltd.
