Improved theoretical equations for infinite network structure

Abstract

In the former paper, the theory in which the perfect network chain structure was assumed as the pyramid type was dealt.
In this paper, the structure is assumed as the infinite network, and the assumptions that 2x-mer chains which appeared after the scissions of cross-link sites do not behave as the effective chains for stress, but behave as those after the scissions of neighbouring xmer chains was presented as the more real one and the improved theory taking these into account was derived.
Furthermore, the theory in which both scissions of main chains and that of cross-link sites nearby occurs at the same time was derived.
