LONG-TIME RELAXATION OF POLYMER NETWORKS

A naive single-chain approximation of the topological constraint release of polymer network strands over the whole time region is discussed. In the long-time limit, the net relaxation of the whole network is predicted to follow the empirical Thirion-Chasset relation. A linear cross-link dependence of the characteristic relaxation time has been found. Further, some common features to random hopping models in disordered materials could be examined.
