Abstract: Both theory and experiment suggest that reptation plays a minor role in the viscoelastic response of polymers in the glassy state. The time for reptation is so long that the entanglement network can be considered to be permanent, at least for deformation far below Tg. We have developed a network picture of a glassy polymer in which mechanical stresses and strains in the solid are represented in terms of forces and displacement in a harmonic lattice with nearest-neighbor interactions.
