Abstract
A concept of the effective relaxation time was introduced to analyze the st ress relaxation curves for a series of monodisperse polymers. It is shown t hat the original reptation model cannot describe the time variation of the relaxation modulus. A model based on the notion of a network of physical bo nds is proposed to describe the relaxation of linear polymers. A quantitati ve agreement between experimental curves and this model is demonstrated.
