Swollen networks scatter more light than solutions of linear molecules of the same concentration. This occurs because of the concentration fluctuations associated with the variation of the local degree of swelling related to variations in the local crosslink density. Measurements are reported on model end-linked bimodal networks of controlled heterogeneity, and compared with theoretical estimates of the effect. The observed discrepancy is indicative of the need for an improvement in concepts of micro deformation of networks during swelling.
