• A molecular theoretical investigation of the viscoelastic of amorphous polymeric substances in the range of long relaxation time has been made using the temporarily cross-linked network-structure-model. The origin of the energy dissipation is ascribed to the slipping of chains and the change of number of chains induced by deformation. when the network structure is deformed each chain will slip since the network structure does not return to its initial state when the deformation is taken off. As the chains slip the deformations of chains do not coinside with that of the network structure. The we introduce the two kinds of deformation tensor, one is the observable deformation tensor of the netwok structure and the other is the inner deformation tensor of each chin. Assuming that the deformation of all chains can be characterized by a single average inner deformation tensor, we obtain Eq. (7) which expresses the relation between the observable and the inner deformation tensors. We can also obtain Eq. (31) expressing the change of the number of chains which depends upon the time and the deformation. Eq. (31) has the same form to that of the chemical reaction as expected by the theory of rate process. The strain free energy of each chain is assumed to depend only on the end-to-end distance of each chain and the free energy depending on the density of segments which corresponds to the inner pressure of the system.
