Abstract
The dynamic mechanical properties of poly(benzyl methacrylate) (PBzMA), and poly(cyclohexylmethyl methacrylate) (PCHMMA) were studied. In order to show the beta relaxation in both polymers and the gamma 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 gamma relaxation spectra of PCHMMA in terms of activation free energy distribution was performed.
