“…11 However, our spectrum is different from those predicted theoretically by Chompff, 3 ' 4 Hansen, 6 and Hong, et al 7 This is due to differences in the models and their approximate calculations. The result of eq 28, 7:max=AM 3 , agrees with theoretical predictions obtained by one of our group, 12 de Gennes 2 and Edwards, 3 although the respective molecular concepts differ from each other. However, this prediction of M 3 differs from M 3 • 4 as suggested by the mechanical data.…”

“…As a result, electrostatic repulsion force caused by negatively charged carboxylic groups among the gel strands decreased, and gel networks in the membrane rearranged and assembled into granular structures (Figure 3). The intermolecular force of alginate with lower molecular weight in solution is less 50 than that of alginate with higher molecular weight. Thus, when the former alginate was formed into calcium alginate gels, the number of cross-linking points between two alginate molecules was less.…”

“…to describe the entanglement effect. Bueche,2 Grasseley, 3 and Chikahisa 4 have treated the undiluted polymer solution case based upon the hypothesis that spheres of the macromolecules moving in the solvent exert some frictional forces on each other. Chompff, Duiser 5 and Prins, 6 Hayashi,7 and Yamamoto 8 considered the polymer chain in the undiluted solution as a Rouse chain having low-mobility points.…”
