Permeability measurements during the sol-gel transition: Direct determination of the nu exponent.

We study the variation of the permeability in the vicinity of the sol-gel transition observed during free-radical copolymerization of acrylamide and bisacrylamide at low concentrations. The main difficulty of the experiment arises from the low values of the elastic moduli which can lead to deformation effects; these have been carefully analyzed. For the first time, the exponent v and the prefactor ^0 of the correlation length have been determined experimentally. We find that v is equal to 0.9 ± 0.1 independently of the concentration while ^g decreases as the concentration is increased.
