N2 - The dynamic mechanical properties of poly(benzyl methacrylate) (PBzMA), and poly(cyclohexylmethyl methacrylate) (PCHMMA) were studied. In order to show the β relaxation in both polymers and the γ relaxation in PBzMA, the derivative of the real part of the complex modulus dE′ dT was calculated, which is proportional to T-2E″. A detailed study of the γ relaxation spectra of PCHMMA in terms of activation free energy distribution was performed.
