Abstract
In this Rapid Communication we present a scaling theory for the elasti city of olympic gels, i.e., gels wherp the elasticity is a consequence of topology only. It is shown that two deformation regimes exist, The first is the nonaffine deformation regime where the free energy scale s linear with the deformation. In the large (affine) deformation regim e the free energy is shown to scale as F chi lambda(5/2) where lambda is the deformation ratio. Thus a highly non-Hookian stress-strain rela tion is predicted.
