Abstract : By extending the theory of Flory and Rehner for the swelling of a crosslinked network which is inhomogeneously crosslinked, it is predicted that local fluctuation in degree of swelling will occur which will lead to fluctuations in refractive index. By utilizing the Debye-Bueche theory of scattering, it is shown that this will lead to enhanced scattering. The analysis of this scattering permits one to evaluate the mean squared fluctuation in crosslinked density as well as the size of the regions within which fluctuations occur. (Author)
