摘要：

The physical meaning of the effective relaxation time as a quantity characterizing the relaxation spectra of polymers is discussed. For monodisperse polymers and their mixtures, some theoretical models and the plots of the relaxational elastic modulus versus frequency are analyzed. A qualitative relationship between the weight-average and number-average relaxation times and their ratio, on the one hand, and the structural and dynamic characteristics of polymer systems, on the other hand, is shown.
