The author proposes a structure model of real cross-linked rubber to explain all phenomena discussed in this series of summary with the fundamentally universal concept. In cross-linked rubber, the cross-linked phase and uncross-linked phase are separated from each other to construct co-continuous structure and dispersed in-homogeneously over the system on the order of 1-5 μm. The uncross-linked phase deforms mainly under the extension of the system, and thus dynamic and fracture properties of cross-linked rubber depend greatly on the characters of uncrosslinked rubber.
