弹性势完全由两个模量Gx和GN决定。它们的总和是平衡模量G，其可以从线性区域中的交联材料上的应力松弛测量获得。结果表明，GN是成比例的GN，同一聚合物的高分子量的非交联样品的平台模量。比例常数似乎是独立的交联密度和聚合物的性质。目前最好的估计是0.354。
Theproposed elastic potential is completely determined by two moduli, Gx and GN. Their sum is the equilibrium modulus, G, which can be obtained from stress relaxation measurements on the cross-linked material, in the linear region. It is shown that GN is proportional to GN, the plateau modulus of a high molecular weight un-cross-linked sample of the same polymer. The proportionality constant appears to be independent of the cross-link density and of the nature of the polymer. Its best current estimate is 0.354.
