Electron diffraction study of regenerated celluloses like viscose, cuprammonium. and polynosic rayons revealed the presence of cellulose I as an extraneous lattice in addition to the basic cellulose II lattice, hitherto shown by x-ray diffraction studies. This paper also investigates the possible causes for the highly unstable nature of the cellulose II lattice in the electron beam.
