A Theory of X-Ray Scattering by Disordered Polymer Crystals

A theory of X-ray diffractions from disordered crystals, which are composed of the polymer molecules of helical structures, is developed. This theory gives the relationships between various disorders in polymer crystals and the diffuse streak diffraction patterns on layer lines as well as Laue-Bragg reflections. The results derived here include those given by Clark and Muus in 1962.
