Abstract

The tube model was used to study the dynamic-mechanical response of the flexible polymer networks. The approach used Rayleighian dissipation function. The dynamic complex modulus was calculated from the analysis of network strand relaxation. The chain equilibrium was achieved by the sliding motion of polymer segments. The characteristic relaxation time of this motion separates the low frequency limit of the complex modulus. Polymer melts and crosslinked networks could be interpolated due to the dependence of storage and loss moduli on crosslink and entanglement densities. A first approximation description of polymer dynamics under small deformations were developed. The dissipative function was used for fluctuations, relaxation and constraints.
