摘要：

We discuss the case of gels prepared by statistical cross-linking of semidilute solutions. When swollen, such gels should show large-scale inhomogeneities related to the random distribution of tie points. We argue that, under uniaxial stretching, the concentration fluctuations spectra should exhibit an unusual anisotropy, which should be revealed by scattering experiments. We expect the scattering intensity in the direction parallel to the stretching to be stronger than in the perpendicular one. © 1990, American Chemical Society. All rights reserved.
