Permutoid reaction

If experience gained from layer lattices is. applied to the chain lattices, which are also frequently named fiber lattices, it is to be expected that the cohesion of the primary valence chains will stamp the whole structure and that permutoid reaction will be present to a still higher degree than in layer lattices, because here the strong cohesion due to primary valence acts only in a single direction. We may further assume that the diffraction effects of such primary valence chains will exhibit certain similarities to diffraction phenomena in linear lattices.
