The interpretation of the equilibrium mechanical properties of polyurethane model networks in the large elongation region has been performed within a theory of tube-like topological constraints. This theory describes the small-strain properties as well as the large-strain properties of the networks in terms of the number of elastically active network chains (EANCs) and structural features contained in the structural parameters T e (trapping factor) and w s (sol content).
