The free energy of polymer chains connected by slip links has been investigated in this work. For the problem of two network chains connected by a single slip link a degeneracy of the free energy surface above the slip-link configuration space was obtained. The degeneracy depends on the lateral separation d of the chains. In the case of d > d(c), where d(c) is some critical distance, the degeneracy vanishes. The reason for this nontrivial free energy behavior is the concurrence of two entropic forces. One is the usual force against stretching of the chains parts and the other is the attempt by system to reduce the influence of the constraint caused by the slip link. For chain configurations with more than one slip link, a tendency for the slip links to form clusters to get a higher amount of entropy can be shown.
