  • Analysis of wide-angle X-ray and neutron diffraction data has shown that the crystal structures of nylon-6 in both α and γ forms, as well as the iodine complex, are composed of statistically disordered arrangements of molecular chains. This composition can alternatively be described as the disordered slippages of sheet planes. The notion of stacking disorder within these sheets enables a logical interpretation of the transition mechanism among the three crystalline phases.

  • The crystal structure of the nylon-6 α form has been established on the basis of wide-angle X-ray diffraction data analysis. We have believed it for the past 70 years. However, the combination of X-ray and neutron diffraction data has required us to introduce the statistical disorderliness to the chain-packing mode as well as revise the space group to that of a higher symmetry. The refined crystal structure makes it possible to perform a more reliable quantitative analysis of the structure‒property relationship of the α form.
