The autocorrelation function of scattered light has been measured for polydimethylsiloxane-toluene gels formed either by swelling permanent networks or by dissolving linear macromolecules at moderate concentrations. In both cases, the cooperative diffusion constant varies with concentration according to a power law with an exponent larger than that obtained previously for polystyrene-benzene systems. On the other hand, it is shown that uniaxial compression moduli do not obey simple scaling laws with the equilibrium concentration for networks swollen by a diluent of less quality than the solvent in which the crosslinking has been made.La fonction d'autocorrélation de la lumière diffusée a été mesurée pour des gels de polydiméthylsiloxane-tol...
