The elastic behavior (uniaxial compression measurements) of PDMS-networks swollen in pure solvents of different thermodynamic quality is described. The results are discussed in the framework of the model for phantom networks. It is shown that the calculated M(C) is a function of the swelling degree and that the corresponding curve consists of two different parts. The shape of the first part can be explained by a change of the microstructure factor A and the second by a change of the memory term eta.
