The molecular mechanism of real rubber vulcanizates, both unfilled and filled, is discussed in relation to the classical non-Gauss/an theory, in which the deviation from theory at large deformation seems to be attributable to the concept of fixed crosslinks in the theory. A new slider model that possesses the characteristic viscous property is introduced to represent physical crosslinks. The slider model is effectively available for interpreting the typical phenomena observed in real rubber vulcanizates, such as the crossing of the stress strain curves measured at different temperatures and the Mullins softening under cyclic deformation.
