膨胀的网络比相同浓度的线性分子溶液散射更多的光。这是因为与局部溶胀度的变化相关的浓度波动与局部交联剂密度的变化有关。报道了对受控异质性的模型末端连接双峰网络的测量结果，并与理论估计的效果进行了比较。观察到的差异表明，在膨胀过程中需要改进网络微观变形的概念。
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.
