Abstract

Small-strain, equilibrium modulus data from 12 different studies on poly(dimethylsiloxane) networks are reviewed. For each network enough structural information is available to permit reasonably accurate calculations of the important network parameters: concentration of elastically active strands and junctions and the trapping factor. These are used to compare all the results. The agreement between the various workers is remarkably good. The results support the theoretical concept that topological interactions between PDMS chains contribute directly to the modulus but not greatly to suppression of junction fluctuation.
