The topological entanglements between subchains of two interpenetrating polymer networks are described in the simplest approximation supposing that the primitive path of each subchain is influenced due to the shift of one network relatively to the other. The entanglement contribution to the free energy of the networks is shown to behave as 1/ q 2 for the state with deviation from uniform densities with the wave vector of order q . This contribution is shown to cause the microphase type of segregation.
