Résumé :

The osmotic second virial coefficient A2(n) of athermal polymer solutions is discussed for a simple lattice model, each molecule (n - mer) corresponding to a self-avoiding walk of n - 1 steps on a simple cubic lattice. The exact evaluation of A2(n) by McKenzie and Domb (up to n = 7) is extended by a Monte-Carlo technique up to n = 40 and it is concluded that for n large A2(n) ≃ 0.58n-0.28.
