A note on ‘sub-Tg relaxation processes in poly(cyclohexylmethacrylate)’

We have critically examined the various relaxation processes occurring in poly(cyclohexylmethacrylate) using dielectric spectroscopy. In addition to the α- and γ-processes found earlier by other workers, we have detected a secondary (β-)process in the temperature range of 293–353 K with an activation energy of about 73 ± 5 kJ/mol.
